                              Use the Energy Savings  Plus  Health  Guide
Purpose
The U.S. Environmental Protection Agency (EPA)
developed the Energy Savings Plus Health Guide
to protect and improve indoor air quality (IAQ) in
schools during building upgrades, particularly ener-
gy efficiency upgrades and building renovation ac-
tivities. Energy management and protection of IAQ
both should be critical priorities for school  facility
management. As school districts pursue energy cost
savings and occupant health-protection goals, there
can be a mistaken impression that the two  goals are
at odds with  each other. In fact, when energy effi-
ciency and IAQ protection goals are integrated and
addressed holistically, schools can achieve strong
results in both areas. Alternatively, if  careful atten-
tion is not paid to the interaction between energy
management and IAQ, occupant  health can suffer.

Background
A school's indoor environment can  have a significant
impact on health and learning. Children, in partic-
ular, are more vulnerable to the negative health and
performance effects of poor environmental  condi-
tions, including IAQ. Children often are more heavily
exposed to toxic substances in the environment than
adults because they spend more  time on the ground
and engage in more hand-to-mouth behavior.  Chil-
dren also breathe more air, drink more water,  and
eat  more food per pound of body weight than  adults
(American Academy of Pediatrics Council on  Environ-
mental Health, 2003). A child's respiratory, immune,
nervous, reproductive,  and skeletal systems continue
to develop throughout childhood. Exposures to envi-
ronmental contaminants that occur early in life can
cause adverse health impacts in children that can
have implications well  into adulthood (EPA Office
of Research and Development, 2007). Furthermore,
some children with  disabilities face unique challeng-
es that might make them particularly vulnerable to
the  effects of an  unhealthy school environment (EPA
State School Environmental Health Guidelines, 2012).
Examples of  symptoms caused by poor IAQ include
respiratory irritation, sore throat,  asthma attacks,
drowsiness, headaches and inability to concentrate.
Studies demonstrate associations between  IAQ and
the  health and performance of students and staff
members in U.S. schools. The research linking poor
IAQ to children's health problems and reduced ac-
ademic performance shows the critical role that a
school's indoor environment plays in student  achieve-
ment. For example, good physical conditions  in the
school and adequate outdoor air ventilation can
reduce absenteeism and  improve test scores.  For  more
information,  examples and supporting references,
see the section of this Guide entitled The Business
Case for Integrating Energy Efficiency and IAQ.
It is important to incorporate best practices for healthy
and sustainable schools into energy efficiency up-
grades and building renovation activities at schools.
Schools can benefit, from both fiscal  and facility
management standpoints, by taking advantage of the
complementary nature of many IAQ and energy-
efficient building practices. Integrating energy efficien-
cy and IAQ improvements—whether they involve the
building structure, equipment or ongoing maintenance
and operations—helps to streamline facility manage-
ment and saves staff members' time. Typically, many
of the same personnel are involved in planning and
implementing energy efficiency and IAQ  programs at
schools. School energy managers, facility managers
and IAQ coordinators should work together through-
out the entire building upgrade process, from the
design phases through construction and occupancy.
Energy management and protection of IAQ both should
be critical priorities for school facility management.
As school districts pursue energy cost savings and
occupant health-protection goals, there can be a
mistaken impression that the two goals are at odds
with one another. In fact, when energy efficiency and
IAQ protection goals are integrated and addressed
holistically, schools can  achieve strong results in both
areas. Alternatively, if careful attention is not paid to
the interaction between  energy management and IAQ,
occupant health can suffer. Energy management activi-
ties can disturb  hazardous materials,  such as asbestos,
lead and polychlorinated biphenyls (PCBs); create
dust; introduce new contaminants and contaminant
pathways;  create or aggravate moisture problems; and
result in inadequate ventilation in occupied spaces.
This Guide focuses primarily on opportunities to protect
and improve IAQ during building upgrades by  prevent-
ing and controlling exposure of occupants to contam-
inants that may be disturbed or introduced during
upgrade projects, controlling moisture, and ensuring
that occupants are provided with adequate ventilation
to promote health and comfort. This Guide does not
(1) set new EPA  regulatory requirements or in  any way
modify or supersede existing EPA regulatory require-
ments, (2) provide guidance on diagnosing occupant
health problems or building-related illness, (3) address
emerging issues that have not been linked to adverse
health effects, (4) make training or training documents
unnecessary, (5) provide detailed  implementation guid-
ance on how to achieve the intent of each recommen-
dation in all situations, (6) identify funding availability
or which programmatic funding sources should be used,
or (7) provide  guidance for prioritizing building-specific
projects during the upgrade process. Portions of this

  Important Basic Considerations for
  Protecting IAQ During Building Upgrades

  Several energy retrofit and building upgrade ac-
  tivities can cause or aggravate IAQ problems as
  described in detail throughout this publication;
  however,  these important basic considerations must
  always be kept in mind:
  • Occupants' and workers' exposure to airborne
    contaminants generated during and after energy
    retrofits and building upgrades activities should be
    minimized.
  Energy retrofits and other building upgrades can
  disturb existing contaminants known to cause
  health problems. Some of these contaminants
  have specific regulatory requirements (e.g., asbes-
  tos, lead) that must be followed.
  • Reducing air leakage across the  building envelope
    should not be performed without  ensuring that there
    will be adequate venting of combustion appliances
    and outdoor air ventilation to dilute and remove
    pollutants from within the building after the project
    is completed.
  Modifications that increase the airtightness of a
  building's envelope increase the potential for ele-
  vated levels of contaminants indoors. Care must al-
  ways be taken to ensure that these activities do not
  cause improper venting of combustion appliances
  and increase occupant exposure to combustion
  by-products, including carbon monoxide; introduce
  increased indoor exposures to  other pollutants, in-
  cluding radon; or introduce or exacerbate moisture
  and mold problems within the school.
Guide summarize certain regulatory requirements, but
the requirements themselves, not the summaries in this
Guide, govern.

Fundamental Principles of IAQ
The guidelines in this document are intended to en-
courage IAQ professionals to integrate health protec-
tions into energy efficiency and building renovation
projects by undertaking the following activities:
  • Integrating strong IAQ protections into the design,
    renovation and construction processes.
  • Commissioning key energy and IAQ systems to
    ensure that they operate as designed.
  • Controlling moisture in building assemblies,
    mechanical systems and occupied spaces.
  • Limiting entry of contaminants from outdoors.
  • Limiting contaminants from indoor sources.
  • Capturing and exhausting contaminants from
    building equipment and activities.
  • Providing adequate outdoor air ventilation.
  • Providing filtration and air cleaning to supplement
    pollutant source control and ventilation.
  • Protecting building elements,  occupants and work-
    ers during construction projects.
  • Ensuring that there is a strong communications
    plan  in place to share the project's IAQ goals with
    occupants and other stakeholders, with a clear
    process for addressing feedback and concerns.
    This  includes, for example,  ensuring that building
    occupants are aware of the  availability of the As-
    bestos Hazard Emergency Response Act (AH ERA)
    Management Plan,  Lead Safety Plan and Material
    Safety Data Sheets.
  • Educating building occupants about the actions
    they  can take to protect IAQ in their school.

States and school districts interested in advanc-
ing this Energy Savings Plus Health Guide for their
K-12 school systems can convene cross-disciplinary
work groups of education,  health,  environmental
and energy representatives to develop state-spe-
cific guidance, including available incentives or
reimbursements. A recent report published by the
Lawrence Berkeley National Laboratory, Financing
Energy Upgrades for K-12 School Districts: A Guide
to Tapping into Funding for Energy Efficiency and
Renewable Energy Improvements  (Borgeson and
Zimring,  2013),  can also be used  as a resource.

How the Energy Savings Plus Health Guide Is
Organized
The Energy Savings  Plus Health Guide covers
23 specific priority issues and addresses com-
mon contaminants associated with building  up-
grades  and critical building systems that affect
IAQ. Each topic is organized in three sections:
Energy Savings Plus Health I  INDOOR AIR QUALITY GUIDELINES FOR SCHOOL BUILDING UPGRADES

-------
Assessment Protocols: Measures to identify potential
IAQ concerns in schools undergoing building upgrades.
Minimum Actions: Critical actions intended to correct
deficiencies identified during the assessments, include
minimum IAQ protections, and ensure that work does
not cause or worsen  IAQ or safety problems for occu-
pants or workers (i.e., "Do No Harm"). Some of the
Minimum Actions identified  overlap with regulatory
requirements but not all regulatory requirements are
listed; others are recommendations for additional steps
to protect and improve IAQ during building upgrades.
Applicable regulatory requirements must be  followed
and the regulations,  not the  summaries  in this Guide,
establish the applicable requirements. Recommended
steps are not mandatory.
Expanded Actions: Additional actions to  promote
healthy indoor environments that can be taken during
building upgrades. EPA recommends considering
these improvements when feasible and  sufficient
resources exist.
The Assessment Protocols, Minimum Actions and
Expanded Actions are designed to incorporate good IAQ
practices into a variety of energy efficiency and other
building upgrade projects. To be effective, the recom-
mended protocols and actions should be  built into the
earliest stages of project conceptualization and design.
Working as a team, energy managers, facility  managers,
IAQ coordinators and risk managers can use the guide-
lines to better understand the interrelationships between
                              energy efficiency and IAQ goals and identify opportuni-
                              ties available during typical energy management tasks
                              to protect and promote healthy indoor environments.
                              Relevant standards and guidance documents for each
                              priority issue are provided in an abbreviated format.
                              More detailed information can be found in the Refer-

The Business Case for Integrating Energy
Efficiency and IAQ

In the coming decades, school districts are likely to
make substantial investments in renovating existing
school buildings and  performing equipment upgrades
(also called retrofits). Because U.S. schools spend
more than $7.5 billion annually on energy to maintain
functioning classrooms and buildings (EPA ENERGY
STARฎ, 2008), many  of the future improvements will
aim to reduce energy use, while providing adequate
ventilation and saving money. When-ever new school
design and construction, major renovations and/or
targeted  building retrofits occur, or whenever regular
operations and maintenance practices are  improved,
school officials have a well-timed opportunity to simul-
taneously protect IAQ, integrate healthy practices and
save money. Through  up-front planning, coordination
and open communication among all stakeholders,
schools can  make this integration work successfully.
                            Studies have demonstrated that increased classroom
                            ventilation rates are associated with improvements in
                            student health and performance. A European study
                            showed that a doubling of the ventilation rate from
                            about 7.5 cubic feet per minute per person
                            (cfm/person) to 15 cfm/person improved speed of
                            academic performance by about 8 percent (Wargocki
                            & Wyon, 2006). A U.S. study in fifth-grade classrooms
                            from 100 schools used student performance in standard
                            academic tests as the  measure of performance and esti-
                            mated that  there was nearly a 3-percent increase in the
                            proportion of students passing standardized math and
                            reading tests for each  2 cfm/person  increase in ventila-
                            tion rate across the range of 2 to 15 cfm/person
                            (Haverinen-Shaugnessy et al., 2011). A recent study
                            also demonstrated that for each 2.1 cfm/person in-
                            crease in  ventilation rate, on  average, the illness
                            absence of  students decreased by 1.6 percent (Men-
                            dell et al., 2013). In some school districts, income
                            from government sources is linked to days of student

attendance; thus, increased ventilation rates may
increase school district income. Indoor temperature
also can affect occupant performance. For example,
one study showed that the average speed of completing
academic work, based on monitoring of performance
of eight simulated school work tasks, decreased by
approximately 1 percent per each 1  ฐF as tempera-
tures increased from 68 ฐF to 77 ฐF (Wargocki & Wyon,
2006). A detailed  discussion of how
IAQ parameters can affect student
health and academic  performance,
with supporting references, can
also be located at the IAQ Sci-
entific Findings Resource Bank
website, hosted by the Lawrence
Berkeley  National  Laboratory.
Well-conceived and coordinated
school energy and IAQ manage-
ment programs can save money.
A report, Greening America's Schools: Costs and
Benefits, reviewed 30 green schools and concluded
that green schools cost on average 2 percent more
than conventional schools, but the financial benefits
derived  are about 20 times greater than the additional
costs (Kats, 2006). "Green" schools were defined as
new schools based on either the U.S. Green Building
Council's Leadership in Energy and Environmental
Design program,  the Massachusetts Collaborative for
High Performance Schools, or the Washington  State
Sustainable School Protocol for High Performance
Facilities. By understanding the relationship between
typical energy management activities and IAQ, and by
following the guidance recommended in this Energy
Saving Plus Health Guide, schools can potentially real-
ize substantial improvements in IAQ and cost savings.
Cost savings from energy efficiency and IAQ integration
can be significant and easy to achieve. For example,
the Blue Valley School District  in Overland Park,
Kansas, identified a leader for its IAQ team and began
with  "quick wins" that would improve IAQ with mini-
mal effort and cost.  Building on these small success-
es, the district moved on to larger and broader goals,
making  strategic connections between energy efficien-
cy and IAQ goals to combine resources and achieve
greater success. A new mechanical  system in one of its
schools  resulted  in not only increased outdoor  air ven-
tilation  but also cost savings of $23,000 annually from
the reduction in energy use. Blue Valley capitalizes
on energy savings and directs money into the operat-

ing budget, which provides resources for more energy
efficiency and  IAQ improvements. The district tracks
outcomes of bond-financed facility improvements
and demonstrates costs savings that then are applied
to IAQ management activities. This is an effective
strategy when the district does not have the budget
to make the initial investment in  improvements and
ultimately helps provide more resources for addition-
                 al projects.  In 2006,  Blue Valley
                 was the first school district in the
                 nation to  receive the IAQ Tools  for
                 Schools National Model of Sus-
                 tained Excellence Award from EPA.
                  Similarly, in Colorado Springs
                  School District 11, the integra-
                  tion of energy efficiency and IAQ
                  had remarkable benefits. The
                  district's energy management
                  program—built on the commit-
ment of the superintendent,  board of education, and
a full-time coordinator—has resulted  in an estimat-
ed annual energy savings of more than $928,000
and significant IAQ improvements. IAQ goals have
been accomplished through energy-efficient design,
proper maintenance and commissioning of HVAC
equipment, and the use of performance-based con-
tracting for improvements in existing  schools. Colo-
rado Springs School District  11 previously won the
ENERGY STARฎ Partner of the Year Award in 2005.
There are measurable costs for not promoting healthy
school environments.  The costs imposed by environ-
mentally  attributable diseases—such  as asthma—on
children,  families and schools are immense (Landrigan
et al., 2002). According to the Centers for Disease
Control and Prevention (CDC), the annual  economic
cost of asthma,  including direct medical costs from
hospital stays and indirect costs (e.g., lost school and
work days), amounts to more than $56 billion annually
(CDC, 2011). For states, a large percentage of these
costs can be attributed to health care expenditures,
lost school days and lost productivity  (e.g., parents
having to stay home to care for a sick child). Given
the amount of time that children spend in school
each day, high-quality school environments are criti-
cally important for ensuring that children are healthy
and able  to perform in the classroom  (EPA State
School Environmental  Health Guidelines, 2012).

An Integrated Approach to Energy Efficiency and  IAQ:
Case Studies of Demonstrated  Results
Blue Valley School District, Kansas:
•   Mechanical retrofit of a 260,000 square-foot (ft2) building resulted in energy cost savings of
    18-20 percent in the first year.
•   Replacement of a heat pump in one building with a new ventilation system resulted in a 30-percent drop
    in energy consumption at the same time as the outdoor air ventilation rates increased.
•   A districtwide environmental management system continually monitors, identifies and pinpoints potential
    energy and IAQ issues early, reducing the costs associated with maintenance staff diagnosing problems.
•   The maintenance of modern equipment is associated with lower costs.
•   There have been fewer IAQ complaints and associated repairs.
•   The long-term goal is  the mechanical upgrades of 100  percent of facilities to capture energy savings and
    improve  IAQ.
For more information, see http://epa.gov/iaq/schools/casestudies/Blue_Valley.pdf.

Colorado Springs School District 11, Colorado:
•   The district's energy program  realizes $1.8 million in annual energy cost savings in comparison with costs
    before the program was established.
•   $55.5 million in energy costs have been saved during the past 12 years as a  result of energy efficiency
    and IAQ  improvements.
•   All new facilities built have the following qualities:
    o  Low energy consumption: Energy use intensity of 25  kBtu/ft2 per year or less.
    o  Low energy use for lighting: 0.7 Watts/ft2 or less of artificial light.
    o  Bright  and well-lit classrooms:  Maintain 35 foot-candles in  classrooms.
•   Ongoing  commissioning keeps energy waste,  and therefore costs, down while ensuring IAQ problems are
    identified and remedied quickly.
•   In 2012, 32 of the district's buildings were certified  ENERGY STARฎ buildings, with low energy costs and
    healthier indoor environments.

Introductory Note for Priority Issues 1.0 Project
Planning/Integrated Design and 2.0 Commissioning
A wide range of school building upgrade projects is
possible, from small-scale retrofits of components/
systems to much  larger and more extensive projects
involving modifications to multiple building systems and
major renovations to the school building.  A project's
planning,  design and commissioning processes will
depend on its  magnitude and unique characteristics.
It is appropriate for  users of this Guide to tailor their
requirements for Priority Issues 1.0  Project Planning/
            Integrated Design and 2.0 Commissioning. For example,
            simpler projects with limited goals and funding may
            need a less formal design process and commissioning
            than larger-scale renovation projects. Project teams
            should be aware of the potential benefits associated
            with adequate project planning and  commissioning
            to ensure that buildings and systems are designed,
            installed and operating as intended  and  in line with the
            schools' expectations and requirements. Assessment
            Protocols, Minimum Actions and Expanded Actions
            related to contaminants and building systems begin
            with Priority Issue 3.0 Moisture Control and Mold.
                       PRIORITY ISSUE 1.0 PROJECT PLANNING/INTEGRATED DESIGN
         ASSESSMENT PROTOCOLS (AP)
 AP 1.1 Gather Feedback on IAQ Conditions in
 the School Building
 Gather feedback from the school's faculty and
 staff,  including the IAQ coordinator (if one
 exists), the custodian and the school nurse.
 Determine locations in the building with  IAQ
 concerns or complaints and gain an understand-
 ing of the current building status to inform the
 project team.
            Conduct stakeholder meetings early
            in the process to further identify
            IAQ concerns and ensure that the
 project meets its stated goals. Stakeholders
 could include, for example, teachers, adminis-
 trators, nurses, maintenance staff, community
 leaders, parents and/or students.
 Use the information gathered in this step to
 guide the IAQ walkthrough inspection of  AP 1.2.

 Notes
 •  A school's IAQ coordinator could be any
    of several professions typically found in a
    school, including a teacher, administrator,
    nurse or maintenance personnel.
 •  If data on school-specific health measures
    are available (e.g., asthma prevalence,
    absenteeism rates), they may help guide the
    IAQ assessment. Some states require schools
    to keep asthma and allergy incident reports,
    which also could be helpful.
               MINIMUM ACTIONS (MA)
MA 1.1 Conduct Collaborative Planning Meetings
Collaboration during renovation projects can allow project
teams to solve problems creatively and with better out-
comes for the building and occupants. These collaborative
meetings can help to identify synergies between building
systems that can significantly reduce energy consump-
tion, promote IAQ and provide cost savings. For best
results, establish cross-functional team meetings from the
very beginning of project planning and continue meetings
regularly through project completion.
For large projects, the first team meeting often is called
a Design Charrette. This is a meeting at which design
professionals meet with building owners, occupants and
other stakeholders to understand their goals and concerns
and brainstorm ways to achieve these goals within the
overall project scope. Include the school's  IAQ coordina-
tor, risk manager,  maintenance staff, nurses and teaching
staff in this process, as staff and other building occupants
often better understand a  building's IAQ issues.

MA 1.2 Formalize Project Goals
For improvement projects that include several building
systems, use the results of the collaborative team meet-
ings and/or Design Charrette to more formally document
IAQ goals for the project in an Owner's Project Require-
ments document, as outlined in MA 2.2. Formalize proj-
ect goals with IAQ considerations as early as possible in
the project planning/design process to allow early consid-
eration of alternative design concepts and avoid problems
that occur when IAQ is treated as an afterthought.

                MINIMUM ACTIONS (MA)
 AP 1.2 Perform an IAQ Walkthrough Inspection
 Perform a building walkthrough inspection to
 further understand IAQ and health concerns.
 Review each space that will potentially be
 included in the project. Conduct the IAQ
 walkthrough inspection during normal school
 operating hours and occupancy conditions.
 If a walkthrough energy audit is performed to
 determine energy conservation opportunities,
 include the IAQ walkthrough inspection as a
 concurrent, integrated process.
 Talk to the energy auditors and ask if they
 or other professionals with knowledge of the
 building can assist with the IAQ assessments.
 Ensure that the auditor/inspector determines
 whether the outdoor ventilation rates are
 sufficient and controls are functional.
 Ensure that the IAQ walkthrough inspection
 includes aspects of pest management to
 evaluate  pest-specific issues (e.g., evidence
 of infestations, pest populations, pesticide
 storage). See Priority Issue 11.0 Pests for
 additional information.
 Ensure that the IAQ walkthrough inspection also
 includes aspects of moisture control (see AP 3.1).
 For more information about IAQ walkthrough
 inspections,  refer to EPA's IAQ Tools for Schools
 Action Kit, which illustrates common  IAQ
 problems found in schools. The Building  Air
 Quality guide created by EPA and CDC may
 also be used as a resource for  IAQ walkthrough
 inspections.  Chapter 5 of the ENERGY STARฎ
 Building Upgrade Manual provides information
 on examining a building and its energy-
 consuming equipment.
MA 1.3 Finalize the Project Team
If a full project team was not selected during AP 1.3,
select the remaining team members. Refer to Appendix A
to assemble the appropriate project team. Make sure that
the design and construction teams include IAQ expertise
and that a representative from the building operation and
maintenance team  is included.
MA 1.4 Hold Regular Team Meetings and Communicate
With Stakeholders
           Hold regular meetings throughout design and
           construction to discuss progress, synergies
           and challenges. Include the project design
and construction teams regularly in  meetings, and ensure
that representatives from the school are present at each
meeting. Refer to the ASHRAE Indoor Air Quality Guide
Section 1.1 for more information on the benefits of
integrated meetings. Regularly communicate project plans
and progress with stakeholders (including staff, teachers
and parents), and promptly respond to concerns.
MA 1.5 Hold a Construction Kick-Off Meeting
           Before  construction begins, hold a
           construction kick-off meeting with the design
           team, general contractor and site  managers
for each trade. Use this meeting to review the overall
design goals related to IAQ and energy efficiency.
Specifically discuss methods the construction team will
use to meet each goal and any requirements for the
construction teams to document their compliance.
Continue integrated team meetings with the design team,
construction team and school  representative(s) regularly
throughout  construction to ensure that any concerns or
questions are addressed quickly, and continue to  provide
updates to staff, teachers and parents. Ensure that the
plan for protecting students and other occupants  during
the construction phases is adequately communicated
throughout  the school community and a formal process is
followed for responding to complaints and concerns.

                       ASSESSMENT PROTOCOLS (AP)
 AP 1.3 Define General Goals and Develop a Communications Plan
             Generally define the project scope, considering IAQ findings,
             energy efficiency goals and project budget. Determine whether
             the project will  be a major renovation or addition, which will
 require a larger project team, or if it will be a smaller system(s) upgrade.
 Ensure that the project's specifications and procurement documentation
 (e.g., Request for Proposals) include the specific IAQ and energy efficiency
 requirements. Develop a  communications plan to share the project's goals
 with occupants and other stakeholders, with a clear process for
 acknowledging and addressing their feedback and concerns.
 AP 1.4 Select a Project Team
 Based on the overall goals of the project, form a project team as outlined
 in Appendix A. When evaluating proposals, ensure that the  project's IAQ
 and energy efficiency requirements are adequately addressed, and ensure
 architects, engineers, commissioning agents and construction teams
 have experience with the type of projects being considered. Ensure that
 proposals include specific requirements for protecting students and other
 occupants during the construction phases, particularly if the building is
 occupied during construction. Make sure that the design and construction
 teams include IAQ expertise.
 Include a representative from each group of stakeholders in the building,
 for example, teachers,  administrators, nurses, maintenance staff, parents
 and students, if possible.
 Note
 Including school maintenance staff on the project team helps to ensure
 that design goals take maintenance challenges into account and that the
 maintenance team understands the design objectives of any new systems.
 School maintenance staff often can service facilities more effectively with
 simpler systems that are easily accessible.

        MINIMUM ACTIONS (MA)
         AP 2.1 Review Commissioning Options
         Commissioning is a quality-focused
         process intended to verify and
         document that buildings and building
         systems are constructed, installed,
         configured and performing in a manner
         consistent with the design  intent. There
         are several types of commissioning:
         •  Commissioning for new systems,
            performed as part of an  improvement
            or new construction project.

         •  Recommissioning, covering any
            previously commissioned systems
            and performed after an improvement
            project  is complete.

         •  Retro-commissioning, covering
            existing systems and performed as
            part of an improvement  project.

         Examples of school building systems
         that have significant potential to impact
         IAQ, and thus should be considered
         during commissioning, include the
         building envelope, HVAC systems and
         associated controls,  kitchen equipment,
         and fume hoods.
         More information about commissioning
         is in Appendix A.
MA 2.1 Designate a Commissioning
Agent
As appropriate for the project, designate
or hire a Commissioning Agent early
in the design process. For smaller
projects, it may be appropriate to
perform commissioning activities
with in-house staff or consultants.
Carefully select a professional with
experience installing, maintaining or
monitoring the types of  systems to  be
upgraded, as someone with extensive
HVAC commissioning experience may
not be an expert in building envelope
commissioning. Refer to the ASHRAE
Indoor Air Quality Guide, Strategy 1.2,
or EPA's IAQ Design Tools for Schools,
Commissioning Guidance, for further
guidance on selecting an appropriate
Commissioning Agent for larger projects.

MA 2.2 Develop the Owner's Project
Requirements Document
Clearly outline the IAQ and energy
efficiency goals of the project by
developing an Owner's Project
Requirements document. This
document will  be used throughout the
design, construction, inspection and
testing phases to ensure that overall
goals are met.
Use results from the following to
determine the  IAQ goals to be achieved
by the project:
•  AP 1.1 Gather Feedback on IAQ
   Conditions in the School Building
•  AP 1.2 Perform an IAQ Walkthrough
   Inspection
•  MA 1.1  Conduct Collaborative
   Planning Meetings
ASHRAE Indoor Air Quality Guide
Strategy 1.2 provides further guidance
on the importance of the Owner's
Project Requirements document.
EA 2.1 Design for Ongoing
Measurement and Verification
Design for ongoing measurement
and verification of IAQ parameters by
including measurement devices, such
as outdoor airflow measurement devices,
carbon dioxide sensors and humidity
sensors. These devices can help identify
IAQ problems caused by occupancy or
building operation and help to quickly
identify malfunctioning systems.

EA 2.2 Plan for Recommissioning

As systems age, operational guidelines
may not be followed, and systems
and their sequences of operation may
degrade.  If significant IAQ complaints
arise or energy consumption suddenly
increases, consider performing an
audit of the building HVAC systems
and hiring a Commissioning Agent to
recommission any systems that are no
longer calibrated  properly. Refer to the
ENERGY STARฎ Building Upgrade Manual,
Chapter 5.

EA 2.3 Conduct Follow-Up Operator
Training

Conduct follow-up training (e.g.,
6 months or 1 year after the initial
training). This will reinforce operator
skills and knowledge and provide
an opportunity for operators to ask
questions after they become familiar
with the upgraded building and systems.
Consider  recording training sessions for
future reference by operators.

                   Projects that include  modifications to the HVAC system, building envelope and
                   cooling towers and projects that  include "innovative" systems (e.g., energy
                   recovery ventilation, under-floor air distribution and displacement ventilation
                   systems) can have an impact on  IAQ and should be commissioned. Even
                   minor system upgrades should include a quality control process, even if full
                   commissioning is not performed.
                   For HVAC system commissioning, refer to ASHRAE's Guideline 0-2013,
                   The Commissioning Process,  and ASHRAE's Guideline 1.1-2007, HVAC&R
                   Technical  Requirements for the Commissioning Process.
                   For building envelope commissioning, refer to ASTM International's E2813-12,
                   Standard Practice for Building Enclosure Commissioning.
                   If existing systems will not be upgraded in the improvement project, but were
                   identified  in the building audit as malfunctioning or not working efficiently,
                   plan to perform retro-commissioning to correct operational deficiencies, control
                   sequences, setpoints and other needed calibrations. For more information, see
                   ENERGY STARฎ Building Upgrade Manual, Chapter 5.

                   MA 2.5 Commission Systems
                   If building envelope modifications or additions are included in the improvement
                   project, the Commissioning Agent should review the envelope design and perform
                   onsite  verification beginning during the early stages of construction.
                   The importance of timing the commissioning activities to protect IAQ is outlined
                   in detail in the ASHRAE Indoor Air Quality Guide, Strategy 1.2.
                   Two valuable aspects of commissioning are prefunctional checklists and
                   functional performance testing that have traditionally been used for
                   commissioning HVAC systems; these can be adapted to other building systems.
                   Prefunctional checklists verify the proper installation of equipment and help
                   identify deficiencies prior to functional performance testing. These checklists
                   are  intended to supplement, not replace, any manufacturer startup checklists or
                   documentation.
                   The goal of functional performance testing is to assess complete system operation
                   and evaluate the interaction of individual components. The scope of functional
                   performance testing includes automated controls, sequences of operation,
                   and equipment function during various modes of operation. Testing criteria
                   include the Owner's Project Requirements and Basis of Design documents,
                   manufacturers' requirements, and sequences of operation.

                        MA 2.6 Deliver a Commissioning Report
                        If a Commissioning Agent was hired to perform commissioning activities, a
                        commissioning report should be provided to the facility manager, the owner
                        or the owner's  representative. The report should include an overview of the
                        commissioning process, prefunctional checks and functional performance
                        testing methods and detailed results,  identified  deficiencies, resolved issues
                        and outstanding problems, including equipment installation and operation.
                        The report should include dates and times for all functional checks and
                        performance tests. The report should address the adequacy of the installed and
                        commissioned  equipment and systems in meeting the contract, Owner's Project
                        Requirements  and the Basis of Design documents. The report should be clearly
                        written and easily understood by all members of the project team.
                        MA 2.7 Post-Occupancy Commissioning
                        Depending on  the functional performance testing schedule and results, deferring
                        certain functional performance tests (or portions thereof) to the appropriate
                        season or weather conditions often is required. Seasonal or deferred testing
                        can capture system performance during times when IAQ may be more acutely
                        affected (e.g.,  when outdoor air ventilation rates are at design minimums during
                        seasonal design weather conditions). Also, performing additional commissioning
                        verification before system warranties expire may identify issues that could be
                        resolved under warranty.
                        MA 2.8 Operator Training
                        The Commissioning Agent should provide training to the facility manager and
                        other operations and maintenance staff on all commissioned systems, which
                        may require a significant time investment. Operations manuals can be  difficult
                        to understand  and may not provide all the information on the building's systems.
                        The Commissioning Agent may have unique insight  into system design and
                        correct operation and should provide thorough training and documentation to
                        facility staff at project completion. The ENERGY STARฎ Building Upgrade Manual's
                        Chapter 5 on retro-commissioning outlines the type of information that should be
                        provided during training. Document attendance  for future reference and potential
                        followup.

      ASSESSMENT PROTOCOLS (AP)
        MINIMUM ACTIONS (MA)
 AP 3.1 Inspect for Moisture Problems
 and Document Results
 Inspect the interior and exterior of the
 building and the building's mechanical
 systems for evidence of moisture
 problems.  Examples of moisture and
 mold problems include the following:
 • Water damage or stains (e.g., on
   walls or ceilings)
 • Foundation cracks that leak water
 • Signs of seepage or wicking (e.g.,
   efflorescence, peeling paint,
   delaminating materials)
 • Visible mold growth
 • Mold growth in duct work and
   plenums
 • Wet or damp spots
 • Musty odor
 • Groundwater, surface water and
   rainwater intrusion
 • Plumbing leaks
 • Condensation or moisture damage  on
   or around windows
 • Other condensation (consider
   surface  temperature, relative
   humidity and dew point temperature
   when evaluating the potential for
   condensation problems)
 Document the extent and locations of
 the problems and the proposed repairs.

 Notes

 • Building staff and occupants may
   be a source of information  regarding
   past and present moisture  problems.

 • The CDC-NIOSH Dampness and
   Mold Assessment Tool may be a
   useful resource for inspecting and
   documenting mold and moisture
   problems in the school.
MA 3.1 Repair Moisture Problems
Repair moisture problems identified
during the assessment (e.g., plumbing
leaks; rain leaks, including leaks around
windows and flashing; foundation
leaks). It is important to correct a
moisture problem at its source.

MA 3.2 Follow Professional Guidance
for Conducting Mold Remediation
                  Conduct any re-
                  quired mold reme-
                  diation following
professional guidance, such as EPA's
Mold Remediation in Schools and Com-
mercial Buildings and Institute of In-
spection, Cleaning and Restoration Cer-
tification (IICRC) Mold Remediation
Standard S520. Do not disturb mold
growth without following professional
guidelines.

Note
EPA does not recommend routine
sampling for mold.  If visible mold
is present, it is important  to correct
the source of the moisture problem
and clean up the mold. For more
information on mold sampling, see
EPA's Mold Remediation in Schools and
Commercial Buildings.

MA 3.3 Address Standing Water
Problems
Address standing water problems
(e.g., surface water pooling near
the foundation, water that does not
drain from flat roofs and gutters).
Ensure that there is adequate slope
and drainage away from the building.
Correct standing water problems  near
foundations and crawlspaces before
insulating and weatherizing.

MA 3.4 Manage Rainwater
Manage  rainwater in assemblies that
are included in the  scope  of work
(e.g., drainage planes and flashings).
Ensure that there is adequate slope
and drainage away from the building,
particularly for downspouts that carry
rainwater from the roof.

MA 3.5 Ensure Proper HVAC Drainage
Ensure that drain pans meet
the requirements of ASHRAE
Standard 62.1.
EA 3.1 Retrofit Crawlspaces
Retrofit crawlspaces so that they are
sealed, insulated, ventilated with
conditioned air,  properly drained
and waterproofed (see EPA Moisture
Control Guidance for Building Design,
Construction and Maintenance, and
the  2012 International Building Code,
Section 1203.3.2).  Install  a high-
capacity, energy-efficient dehumidifier
in the space if the climate  conditions
warrant.
EA 3.2 Perform Additional Mold
Remediation Activities
                   Perform additional
                   activities, beyond
                   those required for
the  building upgrade project, to
remediate any observed mold growth.
Follow EPA or other  professional
guidance.

EA 3.3 Consider Ventilation Approaches
That Provide Better Moisture  Control

Dedicated Outdoor Air Systems (DOAS)
Consider properly designed and
controlled DOAS to precondition the
outdoor air and address the ventilation
and dehumidification loads, with
separate cooling/heating units providing
temperature control  in the occupied
zones, as described  in the ASHRAE
Humidity Control Design Guide for
Commercial and Institutional Buildings,
Chapters 10 and 18.

Note
DOAS systems are typically designed
to provide air at a low dew  point
temperature during humid season
operation and can help control indoor
humidity. DOAS may not entirely
address low indoor humidity problems
during cold,  dry season  operation.

Variable-Air-Volume Systems

Consider properly designed and
controlled variable-air-volume systems
supplying air with a  low dew point
temperature (e.g., 53 to 57 ฐF) to
provide better indoor humidity control.

                 ASSESSMENT PROTOCOLS (AP)
         AP 3.2 Determine Whether Mold Remediation
         is Required
         Determine whether the project requires mold
         remediation and additional moisture control
         measures (e.g., as determined during the
         moisture inspection of AP 3.1 or the IAQ
         walkthrough inspection of AP 1.2).  Remember
         to identify the sources of moisture problems.
         Isolate and contain areas of significant
         mold contamination until these areas can
         be remediated (see MA 3.2; see EPA Mold
         Remediation in Schools and Commercial
         Buildings and IICRC Mold  Remediation
         Standard S520 for additional information).

         AP 3.3 Define Scope for Moisture
         Improvements
         Document which moisture  problems can be
         addressed as part of the building upgrade
         project and which must be repaired before
         certain, specific energy-conserving measures
         can  be implemented. Work with  a general
         contractor or other experienced building
         experts to make these  determinations.

         AP 3.4 Assess for Moisture Problems That Can
         Not  Be Resolved Under the Project
         Significant condensation or humidity problems
         (e.g., condensation on multiple windows,
         condensation in attics, or significant moisture
         or mold problems) may not be possible to
         resolve as part of an energy improvement
         project. In this case, do not start building
         upgrade projects that will reduce the school's
         air infiltration rate or exacerbate the moisture
         problems.
              MINIMUM ACTIONS (MA)
MA 3.6 Prevent Condensation in the Building
Enclosure
Air seal the enclosure and manage air pressure
relationships.
Note
Air sealing the interface between the ceiling and
attic also prevents ice dams on roofs in cold, snowy
climates.
Manage water vapor flow and condensing surface
temperatures to avoid dew point conditions within
the envelope or on other surfaces within the building
whose surface temperature is expected to fall  below
the surrounding dew point temperature (achieved by
selecting materials with the appropriate combination
of thermal resistance [known as the R-value] and vapor
permeability). Strictly follow all applicable building
codes for vapor barrier placement.
Ensure that all piping, valves and ductwork with
condensation potential are adequately insulated to
reduce moisture problems. Perform a quality control
review of insulation after it is installed to ensure
that all surfaces are covered with airtight, vapor-
impermeable insulation,  including surfaces that will
pass through unconditioned spaces.

Control humidity sources.
•  Provide adequate ventilation and air movement,
   paying particular attention to damp and wet areas.
•  Ensure that  existing exhaust fans in potentially wet
  areas (e.g., locker rooms,  toilet rooms, kitchens)
  are operating properly and vented to the outdoors.
   Ensure these exhaust fans are operated when
   needed.
• Cover earthen floors in basements and crawlspaces
  with sealed vapor barriers and seal sump covers.
•  Ensure proper crawlspace ventilation (e.g.,
  foundation wall vents), moisture and humidity
  control for the climate zone.
•  Ensure proper attic ventilation, unless sealed or
  conditioned.
                                                                                                             ACTIONS (EA)

                   MA 3.7 Use HVAC Systems to Manage Moisture
                   Use HVAC systems to manage moisture inside the building.
                   •  Ensure proper sizing when specifying new or replacement air conditioning
                      systems. Be sure to account for all moisture loads in the calculations,
                      including occupants, ventilation air and infiltration.
                   •  If the relative humidity or moisture in the indoor air is high, evaluate whether
                      the air conditioning unit has an oversized design-sensible capacity or an
                      undersized design-latent capacity. Design-latent (dehumidification) capacity
                      of the system should be based on design dehumidification conditions for
                      the location (design dew point temperature and mean coincident dry bulb
                      temperature) as described in the ASHRAE Humidity Control Design Guide for
                      Commercial and Institutional  Buildings, Chapter 10.
                   •  Schools in humid climates may need  dehumidification throughout  the entire
                      year. If constant-air-volume HVAC systems are used in classrooms, provide
                      continuous humidity control based on a scheme that provides dehumidification
                      in response to a humidistat, as described in ASHRAE Humidity Control Design
                      Guide for Commercial and Institutional Buildings, Chapter 18. Alternatively,
                      variable-air-volume systems often can provide better indoor humidity control
                      than  traditional constant-air-volume systems when the dew point at the cooling
                      coil  remains sufficiently low across a range of sensible load conditions.
                   Note
                   In humid climates, temperature  control for constant-air-volume HVAC systems is
                   unlikely to provide adequate humidity control because the ventilation air often
                   will introduce a significant moisture load when there is a very small or negligible
                   sensible heat load. Moisture problems occur when a thermostat controls sensible
                   capacity without regard to latent load (relative humidity or dew point).
                   •  Maintain indoor relative humidity below 60%, ideally between 30% and 50%,
                      if possible, except in spaces in which occupancy and functional requirements
                      dictate otherwise.
                   •  Ensure the regularly scheduled maintenance of humidification equipment
                      installed to maintain a low relative humidity limit, to avoid microbiological
                      problems.
                   •  Ensure proper indoor moisture control during all summer months. Schools
                      are not necessarily vacant during summer months, as some schools have
                      year-round activities (e.g., summer classes, summer day camps). If there is a
                      summer shutdown program for the school building, control indoor moisture by
                      monitoring temperature, relative humidity and condensation and specifying
                      HVAC operation to maintain indoor conditions that prevent moisture/mold
                      problems and maintain the  indoor relative humidity within acceptable limits.
                      Consider incorporating an alarm to alert for an excessive indoor relative
                      humidity or dew point condition.
                   Note
                   Gymnasium floors constructed of maple  typically require an indoor humidity range
                   of 35% to 50% relative humidity to prevent damage. Although brief excursions
                   outside this range (e.g., less than 8 hours) are typically allowed, it is  an important
                   consideration for school building summer shutdown programs.
                   For mechanically ventilated buildings, ensure that building meets the exfiltration
                   requirements of ASHRAE Standard 62.1, such that the minimum outdoor
                   air  intake equals or exceeds the  maximum exhaust airflow, allowing for the
                   exceptions provided in the  standard.

                        as areas around drinking fountains.  If possible, use seamless and slip-resistant
                        materials.
                        Note
                        Floor-covering manufacturers specify the maximum water vapor emission rate of
                        concrete over which coverings such  as tile and carpet can be installed. Installing
                        a covering on concrete that exceeds the maximum emission rate may cause the
                        covering to fail, promote mold growth, and void the manufacturer's warranty. It is
                        recommended that the water vapor emission rate of a floor be measured before
                        coverings are installed (even when the installation occurs long after the building

                        Take precautions to control moisture during roofing modifications.  For example:
                        •  Protect open roof areas from  rain during construction.
                        •  Design and construct roofing systems and flashing details to ensure proper
                           moisture barriers.
                        •  Repair roof leaks before air sealing or insulating the attic.
                        MA 3.10 Protect Onsite Materials From  Moisture
                        Protect materials onsite from moisture damage. Do not  install materials that
                        show visible signs  of biological growth resulting from the presence of moisture.
                        Store and install all building products, systems and components in strict
                        accordance with the manufacturers' printed instructions.

Hazardous  Materials1
             ASSESSMENT PROTOCOLS (AP)
 AP 4.1 Review School's AHERA Asbestos
 Management Plan
 Review the school's AHERA asbestos management
 plan to determine areas of the school that already
 have been identified as containing asbestos. A copy
 of the asbestos management plan can be obtained by
 contacting the school district's AHERA Designated
 Person. The  AHERA asbestos management plan is
 required to be housed in the school's administrative
 office. If an AHERA asbestos management plan is not
 available, see AP 4.2.

 Note
 If a school is subject to AHERA and an asbestos
 management plan is not available, the school is in
 violation of the Toxic Substances Control Act (TSCA).

 AP 4.2 Inspect Building for Asbestos-Containing
 Material
 Verify that a  trained and  accredited asbestos building
 inspector has inspected the building for asbestos-
 containing material (ACM) or, for new construction,
 verify that it  was determined that no asbestos was
 used in the building materials. For schools built
 without asbestos, the Asbestos-Containing Materials in
 Schools Rule pursuant to AHERA (40 CFR Part 763,
 Subpart E) does not require inspections if the building
 architect, project engineer or inspector signs a
 statement to be included in the asbestos management
 plan that no  asbestos was used in the construction of
 the  school building.
 Care must be taken around all building materials that
 may potentially contain asbestos. All school buildings
 have the potential to contain ACM. As required under
 the  Asbestos-Containing Materials in Schools Rule
 pursuant to AHERA (40 CFR Part 763, Subpart E)
 be sure that  any building material that may contain
 asbestos was tested for asbestos or was assumed to
 contain asbestos. This information will help inform
 occupants and construction crews of any ACM present
 before work  is performed.

             MINIMUM ACTIONS (MA)
MA 4.1 Evaluate Condition of ACM and Use
Properly Trained and Accredited Personnel for
Abatement or Repair
Suspected ACM in good condition can be
managed in place, but take caution not to disturb
it. If suspected ACM is damaged (e.g., unraveling,
frayed, breaking apart), immediately isolate the
area(s) and consult a trained and accredited
asbestos professional to determine what corrective
measures should be taken. Trained and accredited
asbestos professionals must separate the work
area in question from occupied portions of the
building using appropriate containment practices.
For suspected  ACM that must be disturbed
as part of the project, contact an accredited
and properly trained asbestos professional for
abatement or repair, in accordance with federal,
state or local requirements. Only a trained and
accredited asbestos professional  may abate,
repair or remove ACM. Contact your state asbestos
regulatory agency for information on how to find
an accredited asbestos professional.

Notes
•  Most states require a license.  In some states,
   however, a training certificate  from an Asbestos
   Model Accreditation Plan course may suffice.
•  Typically, trained and accredited professionals
   can  repair asbestos by—
    o  Sealing or Encapsulating:  Treating the ma-
       terial with a sealant that binds the asbestos
       fibers together or coats the material so
       fibers are not released. Pipe, furnace and
       boiler insulation often can be repaired in
       this  manner.
    o  Covering or  Enclosing:  Placing a protective
       layer over or around the ACM to prevent
       release  of fibers. Exposed  insulated piping
       may be  covered with a  protective wrap or
       jacket.
    o  Removing:  Removing ACM may be advan-
       tageous when remodeling  or making major
       changes to a building that will disturb
       ACM or if ACM  is damaged extensively and
       cannot be otherwise repaired (by covering,
       enclosing, sealing or encapsulating).

                     ASSESSMENT PROTOCOLS (AP)
         AP 4.2 Inspect Building for Asbestos-Containing
         Material (continued)
         Persons who assess ACM must be specifically trained
         under the Asbestos Model Accreditation Plan, in
         addition to those who inspect and perform response
         actions. Refer to the EPA Asbestos: School Buildings
         Web page for a discussion of the AHERA regulatory
         requirements.
         If ACM is present in the school building and there
         is not an asbestos  management plan for the school,
         prepare an asbestos management plan to  prevent or
         reduce asbestos hazards.

         Note
         It is a significant violation of TSCA if an asbestos
         management plan  was not prepared for the school
         building prior to occupancy.
         Contact a trained and accredited asbestos professional
         to perform the asbestos inspection and prepare the
         asbestos management plan. For schools, the asbestos
         management plan  shall satisfy the requirements under
         the implementing rules of AHERA, as published in
         40CFR, Part  763, Subpart E.

         Note
         Possible sources of asbestos include the following:
         • Insulation in attics and attic-like spaces
            (e.g., vermiculite)
         • Wall insulation (e.g., vermiculite, insulation blocks)
         • Hot water and steam pipes coated with asbestos
            material or covered with an asbestos blanket or tape
         • Oil and coal furnaces and door gaskets with
            asbestos insulation
         • Vinyl flooring (including 9 "by-9" or 12 "-by-12" floor
            tiles, vinyl sheet flooring, and the mastics and other
            adhesives used  to secure the flooring)
         • Cement sheet, millboard and paper used as
            insulation around furnaces and wood- or coal-
            burning appliances
         • Soundproofing or decorative surface materials
            sprayed on walls or ceilings, including  popcorn
            ceilings
         • Patching, joint compounds, and textured paints on
            walls and ceilings
         • Roofing, shingles and siding (including cement or
            adhesives)
         • Transite (cement and asbestos) combustion vent or
            transite flue
         • Plaster that is old enough to potentially contain
            asbestos
         • Heat-resistant fabrics
            MINIMUM ACTIONS (MA)
MA 4.2 Precautions for Working Around ACM
When working around ACM, do not—
•  Dust, sweep or vacuum ACM debris.
•  Saw, sand, scrape or drill holes in the material.
•  Use abrasive pads or brushes to strip materials.

MA 4.3 Ensure  Insulation Is Asbestos-Free Before
Disturbing
Do not remove or disturb insulation  that appears
to be vermiculite (e.g., attic or wall  insulation).
The EPA Asbestos website provides information
on vermiculate insulation and how to identify it.
Since confirming whether vermiculite contains
asbestos by testing is unreliable, EPA recommends
assuming it contains asbestos and managing
accordingly. Specifically, EPA recommends that
building owners take the following precautions:
•  Leave vermiculite insulation undisturbed in
   attic or walls.
•  Do not store boxes or other items in  the attic if
   it contains vermiculite insulation.
•  Hire a professional asbestos contractor  if there
   are plans to remodel or conduct renovations
   that would disturb the vermiculite in the attic
   or walls to  make sure that the material is safely
   handled and/or removed.

MA 4.4 Conduct Asbestos Abatement Before
Blower Door Testing
Any asbestos  abatement or repair work should
be completed by properly trained and accredited
asbestos professionals prior to blower door testing.
Exercise appropriate caution  when conducting
blower door testing where friable asbestos or
vermiculite attic insulation is present to avoid
drawing asbestos fibers into occupied spaces
(e.g., positively  pressurized blower door testing).

     ASSESSMENT PROTOCOLS (AP)
                    If unsure
                    whether
                    material
 contains asbestos, contact a qualified
 asbestos professional to assess the
 material.
                     MINIMUM ACTIONS (MA)
MA 4.5 Asbestos Clearance Air Monitoring
Following an asbestos response action in the school (asbestos
abatement corrective action) pursuant to 40 CFR Part 763.90,
asbestos air testing (so called "clearance" testing)  must be
performed to ensure that the response action was properly
conducted. Contact your state asbestos regulatory agency for
information on how to find a trained and accredited asbestos
professional to perform this work.

Notes:
                   Appropriate identification of ACM is necessary
                   to ensure the continued safety of the occupants
                   and the safety of workers, who may not be
aware of asbestos hazards. If ACM may be disturbed during a
planned project, a properly trained and accredited person needs to
conduct an initial asbestos assessment to determine potential
worker exposures and required exposure controls. Asbestos
awareness training is required for custodians and school
maintenance personnel when ACM is present in the school building
(see EPA's Asbestos: School Buildings Web page for more
information).

            ASSESSMENT PROTOCOLS (AP)
         AP 5.1 Assume Lead-Based Paint
         Is Used in Schools Built Before
         1978
         Assume there is lead-based paint
         in schools built before 1978
         unless testing shows otherwise.
         Recognize, however, that lead-
         based paint may be present in any
         school. Determine whether paint
         will be  disturbed by the work or
         the assessment.

         AP 5.2 Test Suspect Surfaces
         That Will  Be Disturbed
         Three methods may be used.
         Paint samples may be taken and
         analyzed  by an EPA-accredited
         laboratory. In addition, a certified
         risk assessor or inspector may
         test paint via X-ray fluorescence
         testing. Finally, in  certain
         circumstances, a certified
         individual may use an EPA-
         recognized test kit to determine
         whether the paint  is lead-based.
         The lead-safe work practices (see
         Minimum and Expanded Actions)
         apply unless paint is tested and
         found not to be lead-based.

         Note
         If there are concerns about lead in
         drinking water, see EPA's Drinking
         Water in Schools & Child Care
         Facilities website.
          MINIMUM ACTIONS (MA)
MA 5.1 Comply With EPA's Renovation,
Repair and Painting (RRP) Program Rule
Among the rule's key elements are the
following:
•  Use a trained and certified renovator
   employed by a lead-safe certified firm.
•  Follow lead-safe work practices if
   disturbing greater than 6 ft2 of interior or
   20 ft2 of exterior  painted surfaces.
•  Contain the work area to avoid occupant
   exposure.
•  Minimize lead dust and leave no dust or
   debris behind.
•  Clean according to specified protocol and
   satisfactorily perform cleaning verification
   or clearance testing.

Note
Compliance with EPA's RRP Program Rule is
required in schools, or portions of schools,
where children younger than 6 years of age
are present. This Energy Savings Plus Health
Guide recommends RRP Program Rule
compliance for all schools, regardless of the
age of the students  or the school.

MA 5.2 Comply With Local and State Lead
Regulations
Comply with local and state regulations that
may be  applicable to lead hazard-reduction
activities and may require additional certified
personnel.

Note
This is not a complete summary of the
regulatory requirements. The intent of
this Guide is to promote the most health-
protective steps that are feasible and
practical. The  minimum action recommended
in this Guide is to comply with whatever the
most current version of the RRP Program
Rule prescribes and with all local and state
regulations that may apply.
EA 5.1 Follow Additional Lead-Safe
Rehabilitation Practices
Follow additional lead-safe
rehabilitation practices, such as the
U.S. Department of Housing and Urban
Development's (HUD) practices outlined
below. In addition to EPA's RRP
Program Rule, adhere to the following:
• Lower the thresholds for interior
  painted surface area from 6 ft2 to 2 ft2.
• Require repair of painted surfaces
  that are disturbed when using lead-
  safe work practices.
• Require meeting lead dust clearance
  testing  standards (as tested  by an
  EPA-certified risk assessor) if more
  than 2 ft2 of paint is disturbed.

Note
Lead dust clearance testing includes
measuring for lead dust on floors,
windowsills and window troughs.

EA 5.2 Replace Windows Containing
Lead-Based  Paint
Replace windows that test positive for
lead-based paint, complying with EPA's
RRP Program Rule and other regulations
that may be  applicable to lead  hazard
reduction activities.

EA 5.3 Ensure All Paint Used in the
Future Is Lead-Free
Some coatings are  exempt from
lead-containing paint regulations.
These include coatings for industrial
equipment and those used for building
and equipment maintenance coatings.
Ensure that all future paint applications
in the school are lead-free. See
Consumer Product  Safety Commission
(CPSC) FAQs: Lead  In Paint (And Other
Surface Coatings).

     ASSESSMENT PROTOCOLS (AP)
AP 6.1 Determine Whether Fluorescent
Light Ballasts Containing PCBs Are
Present
Some schools may contain fluorescent
light fixtures with  ballasts manufactured
before  1979 that contain PCBs.
Ballasts manufactured between 1978
and 1998 that do not contain  PCBs
were required to be labeled "No PCBs."
Newer fluorescent lighting typically uses
electronic ballasts that do not  contain
PCBs and should be clearly marked as
electronic.
If fluorescent light ballasts do  not have
the statement "No PCBs" or are not
marked as electronic, assume  that the
ballasts contain PCBs or contact the
manufacturer to determine whether
the ballasts contain PCBs. If the
manufacturer is not sure whether the
ballasts contain PCBs, assume that they
do.

AP 6.2 Assess Caulk That Will Be
Disturbed
Assess  whether caulk will be disturbed
during  upgrade activities. Many school
buildings built or renovated between
1950 and 1978 have been found to
contain PCBs in caulk. Typical locations
include around windows, door  frames,
masonry columns  and other masonry
materials.
Note
PCBs were not added to caulk after
1978;  however, caulk containing PCBs
manufactured before 1978 could have
been used in buildings after that time.
        MINIMUM ACTIONS (MA)
MA 6.1 Replace PCB-Containing Light
Ballasts
Whether PCBs are confirmed or
assumed to be present, new lighting
fixtures can be used to replace the
existing fixtures. PCB-containing
light ballasts that are leaking must
be replaced and properly disposed of
pursuant to EPA regulations. Any oil
and stains leaked from PCB-containing
ballasts must also be properly cleaned
up or disposed of in accordance with
the PCB decontamination or disposal
regulations. EPA recommends that
nonleaking PCB-containing light ballasts
also be replaced because of their
increased likelihood to fail and leak
and because of the increased energy
efficiency of new ballasts.

MA 6.2 Properly Dispose of PCB-
Containing Light Ballasts
When removing PCB-containing light
ballasts, specific  notification, packing,
reporting, storage, transportation and
disposal requirements apply. The EPA
PCB-Containing Fluorescent Light
Ballasts (FLBs) in School Buildings
Web page provides details on managing
and disposing of both leaking and
nonleaking ballasts, including detailed
federal requirements in 40 CFR Part
761 that must be adhered to (disposal,
use of containers, proper storage,  etc).
Ensure that waste management also
meets local and state requirements.

Note
Fluorescent light bulbs contain small
amounts of mercury. Ensure that the
bulbs are handled properly to avoid
breakage and release of contaminants.
More information on fluorescent bulb
disposal requirements may be obtained
from your state solid and hazardous
waste agencies. See also MA 21.4
Prevent Mercury Exposure.

EA 6.1 Conduct an Assessment for
PCBs in Indoor Air and Mitigate as
Appropriate
If there are additional concerns about
PCBs, consider conducting an IAQ
assessment for PCBs following EPA's
Compendium Method TO-4A (high air
volume) or Compendium Method
TO-10A (low air volume). If the air
quality test indicates concentrations
above EPA's  Public Health Levels for
PCBs in Indoor School Air,  identify
potential sources of  PCBs and
mitigation options. Examples of key
mitigation options include ballast and
caulk removal, proper ventilation and
proper cleaning.
Disposal of caulk or  other building
products contaminated by PCB-
bearing caulk must follow regulatory
requirements for PCB waste, as
described  in 40 CFR Part 761
Subpart D.
Document and store copies of all test
results. Include documentation of
all sampling locations and disposal
measures, including disposal companies
used and final destination of waste
materials.

Outdoor Contaminants and Sources
          ASSESSMENT PROTOCOLS (AP)
 AP 7.1 Select a Radon-Testing Professional
 Qualified measurement professionals are
 individuals who have demonstrated a minimum
 degree of appropriate technical knowledge
 and skills specific to radon testing in large
 buildings (1) as established  in certification
 requirements of the National Radon
 Proficiency Program (director@aarst.org) or the
 National Radon Safety Board (info@nrsb.org)
 and (2) as required by statute, state licensure
 or certification program, where applicable.

 AP 7.2 Perform Radon Testing Before School
 Building Modifications

 Perform radon testing for the school in accor-
 dance with  the current applicable standard
 of practice; such as "Radon Measurement for
 Schools and Large Buildings" (American Na-
 tional Standards Institute [ANSI]/American As-
 sociation of Radon Scientists & Technologists,
 Inc. [AARST] MALB), and state or federal re-
 quirements. The standard includes information
 on which rooms of the school to test, and how
 and when to conduct testing. Assess the HVAC
 systems for proper operation  prior to and while
 conducting the initial radon measurements
 (e.g., ensure that systems are operating as de-
 signed with the design minimum amounts of
 outdoor air  ventilation).
 The current applicable standard of practice,
 such as in ANSI/AARST MALB, lays out testing
 options, which are generally dependent upon
 the device used.

 Option 1: Short-Term Test
 Because radon levels vary from day-to-day and
 season-to-season, a short-term test is  less likely
 than a  long-term test to provide an average
 radon level  for a school year.  A short-term test
 is the quickest way to test for radon, requiring
 a period between 2 and 90 days, depending
 on the  device. Short-term testing should be
 conducted as described in the  most current
 standard of practice.
                                                        PRIORITY ISSUE 7.0 RADON
               MINIMUM ACTIONS (MA)
MA 7.1 Mitigate High Radon Levels
If the results of radon testing (before or after building
modifications) indicate that the average radon levels in
parts or all of the school are >4 picocuries per liter (pCi/L),
take actions to reduce the radon levels, as described
in the current version of "Radon Mitigation in Schools
and Large Buildings" (ANSI/AARST RMS-LB). Active
soil depressurization is the first mitigation method to be
considered. Ensure that radon mitigation professionals meet
state certification requirements, as applicable, and are
certified by either of the groups listed in AP 7.1.

MA 7.2 Ensure  HVAC Systems Are Operating Properly
School ventilation systems play a critical role  in
building performance and must be operating with
no less than design minimum outdoor air ventilation
rates whenever school rooms are occupied (even if at
reduced occupancy) to ensure radon levels are not
adversely affected. Decreasing outdoor air ventilation
rates will tend to increase radon levels. Thus,  a room
with radon test results below 4 pCi/L and the  HVAC
system operating with the design minimum amount of
outdoor air ventilation could have elevated radon levels
if ventilation is decreased. This is particularly critical
for schools without active soil depressurization radon
mitigation systems. Outdoor air ventilation should not be
decreased below design minimum values when spaces
have reduced occupancy,  unless radon testing shows that
radon levels do  not increase above 4 pCi/L when less
ventilation is provided.

MA 7.3 Advise Periodic Retesting of Areas That Have
Been Mitigated  for Radon
Advise  school personnel that retesting should  be
performed according to AP 7.2 and AP 7.3, and ensure
that a long-term risk management plan is provided by
the mitigation professional in accordance with ANSI/
AARST RMS-LB. The plan should contain the essential
information that the school needs to conduct  basic
maintenance and risk management.
Ensure that this is included in the written documentation
for the  renovation project. Retesting should be
performed at least every 2 years or according to the risk
management plan.

                            ASSESSMENT PROTOCOLS (AP)
         Option 2: Long-Term Test
         A long-term test remains in place for more than 90 days, and
         preferably during the entire school year to give an accurate
         representation of radon levels at all times of the school year.

         Notes
         •  Identifying elevated radon levels in a school prior to other building
            upgrades or renovations will allow radon  mitigation systems
            to be considered and installed as part of the overall building
            modifications.
         •  If a school has previously been tested for radon using appropriate
            testing protocols as required by the state where the measurements
            were conducted,  or in absence of state requirements, in accordance
            with the applicable ANSI-approved standard and with no building
            modifications since the testing, the results may be used for the
            purposes of this assessment.
         •  ANSI/AARST MALB provides a table of steps to take during a radon-
            testing program,  along with detailed descriptions and guidance.
         •  Spaces served by demand-controlled ventilation systems may
            require special attention during radon testing, as these systems
            allow ventilation rates to vary with occupancy. For radon testing in
            these spaces, assume a minimum outdoor air ventilation rate based
            on the minimum expected occupancy.

         AP 7.3 Retest for Radon After School Building Modifications
         Retest for radon after all building upgrades and renovations that affect
         building envelope leakage and airflows are completed, as changes to
         the building envelope and  mechanical systems can affect indoor radon
         levels.

         ASSESSMENT PROTOCOLS (AP)
 AP 8.1 Evaluate Potential Sources and Odors
 Visually evaluate potential sources and check
 for odors of gasoline, sewer  gas or fuel oil.
 AP 8.2 Evaluate the Sewer Vent System
 Visually evaluate the integrity of the sewer
 vent system (e.g., ensure that drain traps have
 water  in them, inspect drain lines for breaks
 or leaks, check for apparent blockages),
 particularly if there is sewer gas odor in the
 school (e.g., during the initial assessment or a
 fan  depressurization test).

 AP 8.3 Take Proper Actions if the Odor Source
 Cannot Be Identified
 If an odor is detected but its source cannot be
 identified, and the school is in a  known area of
 contamination, notify local or state  authorities
 and/or pursue additional assessments before
 continuing project work.

 AP 8.4 Conduct  Further Assessment if
 Contamination Is Suspected
 If soil  or groundwater contamination is
 suspected on or near the building site (e.g.,
 former industrial site), volatile contaminants
 or breakdown products may pose an IAQ risk
 through soil gas intrusion. In such cases, EPA
 recommends further assessment  before air
 sealing. Consult your state or tribal  voluntary
 Brownfields cleanup  program or environmental
 regulatory agency for information on the  risks
 of vapor intrusion in your area. EPA's School
 Siting Guidelines provide information for
 assessing prior uses of the site and screening
 for potential environmental  hazards, including
 vapor  intrusion. ASTM E2600 describes a
 tiered approach for screening properties for
 vapor  intrusion and Table X5.1 of the standard
 provides a list  of state vapor-intrusion
 guidance websites.

 Note
 A records search of the property and surrounding
 properties may provide information regarding
 past uses and spill reports.
          MINIMUM ACTIONS (MA)
MA 8.1 Repair Unattached Sewer Vent
System Components
Repair or replace failed or unattached sewer
vent system components before proceeding
with building upgrade projects.

MA 8.2 Address Drain Traps Prone to Drying
Out
If the  assessments reveal sewer gas odors
from drain traps that are dry because of
infrequent use,  develop a maintenance
plan to periodically add water to the traps
to maintain a seal against sewer gases.
Consider installing inline drain trap seals to
floor drains prone to drying out.

Note
Because of their continuous usage, drain
traps  in sinks, toilets or drinking fountains
seldom are a  problem. Usually it is a floor
drain  in an obscure location, such as the
mechanical room, shop area or janitor's
closet. Dry drain traps in mechanical rooms
are especially problematic because the
mechanical rooms often contain heating,
cooling and ventilation systems that can
quickly spread the gases and odors to other
parts  of the building. Unitary equipment
(e.g.,  heat pumps) can have dry drain traps,
which often results in the undesirable odors
being limited to one room.

MA 8.3 Assess and Mitigate Soil Gas Vapor
Intrusion
If soil  gas vapor  intrusion is suspected,
assess and  mitigate in compliance with
local or state  standards. Table X5.1 of
ASTM E2600 provides a list of state vapor-
intrusion guidance websites. If there are no
such standards, follow the EPA guidance
referenced  below for vapor-intrusion
evaluation and mitigation.
Note
The causes or sources of contaminants
must  be identified and corrected before  air
sealing or other weatherization actions are
performed to  ensure that the problem is not
exacerbated.
   EXPANDED ACTIONS (EA)
EA 8.1 Install Floor Drain
Seals to Untrapped Floor
Drains
If there are untrapped
floor drains, install inline
floor drain seals to provide
protection against sewer
gases.

EA 8.2 Install Automatic
Drain Trap Primers
Install automatic drain trap
primers, available from
several major manufacturers,
in drain traps that are
susceptible to drying out to
ensure that a small amount
of water is periodically
delivered to the trap.

EA 8.3 Take Proper Measures
for Brownfields Sites During
New Construction or Building
Expansion
Projects located on
Brownfields sites (as
classified by a federal, state

 AP9.1 Investigate Complaints
 About Motor Vehicle Exhaust
 Emissions
 Ask the school nurse, facilities staff
 and the school's IAQ coordinator
 whether there have been occupant
 complaints regarding vehicle
 exhaust entering the building. If
 complaints have been recorded,
 obtain  more information as to when
 and where complaints originated.

 AP 9.2 Identify Air Leaks From
 Parking Structures
 If there are attached or enclosed
 parking structures, identify the
 location of air leaks from the
 parking structures to occupied
 spaces that might provide
 pathways for hazardous or  irritating
 emissions to enter occupied
 spaces. For example, look for
 doors; overlooking windows;
 and leaks around walls, doors,
 windows, ceilings, duct work, air
 conditioners, and electrical and
 pipe penetrations.

 AP 9.3 Identify and Assess Outdoor
 Air Intakes
 If there are loading docks or vehicle
 loading/unloading zones (e.g.,
 school  bus and  parental pick-up
 areas), identify the location of
 outdoor air  intakes and  assess
 whether they are located an
 adequate distance away from areas
 where vehicles may idle. Determine
 whether these separation distances
 meet the requirements specified in
 ASHRAE Standard 62.1,
 Table 5.5.1.
MA 9.1 Restrict Idling at School Bus Loading/
Unloading Zones, Other Student Pick-Up Areas and
Loading Docks
Some local and state governments already have
anti-idling laws or policies that must be followed.
Otherwise, require engines be shut off (no-idle zone)
at school bus loading/unloading zones, parental pick-
up areas, loading docks, and other vehicle loading
and unloading zones. Provide signage to designate the
limits of no idle zones.

MA 9.2 Seal Locations That Separate Parking
Structures from Occupied Spaces
Minimize the movement of vehicle exhaust pollutants
into the building by air sealing the walls and/or ceilings
that separate parking structures from occupied  spaces.
At a minimum, air seal these  locations (if present):
• Leaks into ceiling cavities
    o  First-floor soffits at ceiling level
    o  Single- or two-story roof-wall joints
• Windows: Ensure tight closure and install weather-
  stripping. If windows currently provide make-up air
  for corridor or toilet exhaust, new make-up air must
  be  provided to those rooms.
• Doors: Ensure tight closure and install weather-
  stripping.
• Electrical, plumbing and duct penetrations
• Cracks between masonry or concrete walls and
  unsealed  penetrations
• Leaks in the duct work or air-handler platforms
  and gaps around  the duct work penetrating to the
  occupied space

MA 9.3 Maintain Positive Pressure in Occupied Spaces
Near Parking Structures
Maintain occupied spaces and vestibules at a positive
pressure relative to adjacent parking structures.
Pressure differentials are typically achieved  by using
outdoor air; however, to effectively protect IAQ, outdoor
air intakes must be  located a sufficient distance
from potential sources of vehicle exhaust, emergency
generator exhaust and other combustion exhausts (see
MA 9.6).
A system that uses transfer air from other portions
of the building to provide pressurization in spaces
near parking structures can be designed, as long
as ASHRAE  Standard 62.1 outdoor air ventilation
requirements also are achieved.
EA 9.1 Relocate Existing
Outdoor Air Intakes
If feasible, relocate existing
outdoor air intakes away from
vehicle exhaust sources to
avoid entrainment (see
MA 9.7).

EA 9.2 Install Filtration and
Air Cleaning for Outdoor
Pollutants
Install particle filtration
and, in extreme cases, gas-
phase air cleaning to treat
ventilation air for outdoor
pollutants (see EA  18.2 and
EA 18.3).

EA 9.3 Add Pressurized
Vestibules at  All Doorways
Connected to Parking Areas
Add  a positive-pressure
vestibule at each doorway
connecting occupied spaces
to a  parking structure, to
provide an airlock.

EA 9.4 Install or Upgrade
Exhaust Systems for Vehicle
Parking Areas
Install or upgrade exhaust
systems for enclosed parking
areas:
• Provide adequate exhaust
  for all localized sources of
  contamination.
• Maintain sealed  exhaust
  ductwork under a negative
  pressure in plenum
  spaces.
• Exhaust to the outdoors,
  meeting the minimum
  separation distance
  requirements of  ASHRAE
  Standard 62.1,

            MINIMUM ACTIONS (MA)
MA 10.1 Meet Outdoor Air Filtration and
Air-Cleaning Requirements of ASHRAE
Standard 62.1
When the school building is located in an area
where the outdoor air exceeds the national
standards for particulate matter (PM25or PM10)
or ozone, ensure that the outdoor air treatment
requirements of ASHRAE Standard 62.1,
Section 6.2.1 are met for mechanical ventilation
systems. This includes the following:
•  Particulate-matter filters or air-cleaning
   devices with a Minimum Efficiency  Reporting
  Value (MERV) of at least 6 shall be  used in
  areas where the national standard for PM10 is
  exceeded.
•  Particulate-matter filters or air-cleaning devices
  with a MERV of at least 11 shall be used in
  areas where the national standard for PM25 is
  exceeded.
• Air-cleaning devices to remove ozone shall be
   used in areas where the most  recent EPA design
  value exceeds 0.107 ppm. The devices  shall
   have a volumetric ozone-removal efficiency of
  at least 40% and be operated whenever the
  outdoor ozone levels are expected to exceed
   0.107 ppm.

Note
At the time ASHRAE Standard 62.1-2013 was
published, it identified only four counties in the
United States with 8-hour ozone design values
exceeding 0.107 ppm, as of July 31, 2013.
Ensure that any increased level of filtration or
air cleaning does not create too much static
pressure within the HVAC system, which could
cause inefficiencies, an increase in energy use
or reduced equipment life. For existing systems,
check with the manufacturer to determine  whether
filters with higher MERV ratings can be installed,
and install filters with the highest rating that can
be accommodated by the equipment.
        EXPANDED ACTIONS (EA)

from a professional who ensures IPM practices
with his or her pest management services (some
examples may include Greenpro, Greenshield or
equivalently certified IPM professionals).
Determine whether pesticides will need to
be used and follow the school district's Pest
Management  Plan/Policy for pest control.
Whenever pesticides are applied, the pesticide
label must be followed, as it is the law.
Consider providing signage to  communicate when
pesticide applications will occur. The signage
should be posted  prior to  the application (e.g.,
1 week) and include dates when the application
will take place. Encourage scheduling pesticide
applications when school  is not in session.
Do not begin work in pest-infested zones until
infested materials are  properly removed. In some
cases, professional assistance may be needed to
remove  infested materials.

Note
Many states require that pest  management
professionals be licensed.

MA 11.2 Patch Openings in Areas of Rodent
Infestation
In areas with evidence of  rodent infestation,  patch
and seal exterior holes that are larger than 1/4"
by 3/8"  with pest-resistant materials (e.g., copper
mesh, hardware cloth, sheet metal,  concrete)
before applying weatherization materials that may
be susceptible to  gnawing by rodents (e.g., caulk,
foam or insulation).

MA 11.3 Reduce  Potential for Pest Entry
Block, seal and eliminate pest entry points
around the building envelope. Examples include
gaps around doors and windows; between the
foundation and the upper portion of the building;
and around utility pipes, conduits and wires.

MINIMUM ACTIONS (MA)
                MA 11.4 Block Pest Movement Through Building
                Reduce risk of pest dispersal throughout the building by sealing and blocking passageways that pests
                can use to move freely to obtain food, water and harborage. This includes gaps around floor and
                ceiling joists;  penetrations in walls, floors and ceilings; and openings around shafts and chutes.

                MA 11.5 Protect Outdoor Air Intakes and Exhausts
                Protect air intakes from bird and pest entry (e.g., cover openings with corrosion-resistant Vfc-inch
                screen or galvanized mesh). Similarly, protect exhaust vents from rodent, bird and  pest entry
                (e.g., cover openings with  louvers). Avoid creating conditions that can clog exhaust vents. Advise
                facility managers to regularly inspect, clean and repair screens or louvers over air intakes and
                exhausts (e.g., at  least semi-annually or  when replacing HVAC filters). Make sure that rooftop air
                handlers are air sealed to their roof curbs to reduce pest entry.

                MA 11.6 Maintain Existing Pest Protections
                Do not disturb or eliminate any building-related materials that are in place to exclude pests.

                MA 11.7 Keep Vegetation  and Clutter Away From Building and Mechanical Systems Components
                Remove clutter, eliminate wood  piles and waste near the building, and remove any bushes, trees or
                other vegetation within 2 feet  of the structure.  Keep vegetation away from outdoor air intakes and
                outdoor mechanical equipment. Do not pile soil or mulch against the building's exterior walls.

                MA 11.8 School IPM Plan
                Ensure that the school has an IPM plan. Refer to EPA's Integrated Pest Management in Schools
                brochure and website for more information. The IPM checklist provided  in EPA's IAQ Tools
                for Schools Action Kit also can  be used as an  example. Preventive IPM measures are easy
                to implement  and often improve the overall maintenance of  the school. These measures can
                include the following:
                •  Maintaining good sanitation practices
                •  Installing high-density door sweeps
                •  Restricting areas in which  food is eaten
                •  Moving dumpsters and food disposal containers away from the school, and maintaining the
                   containers in good condition
                •  Pressure-cleaning food service areas
                •  Sealing cracks and crevices
                •  Cleaning gutters and directing water flow away from building to prevent saturation
                A successful  IPM  program takes advantage of all pest management strategies, including
                prevention, inspection, communication,  biopesticide use, and  judicious and careful use of
                pesticides when necessary.
                Follow IPM guidelines for roach control and consider  using baits over  broadcast applications
                when possible, to reduce possible pesticide exposure.

When installing new products and
materials, use the least toxic product
or material feasible to effectively do
the job. For example, use products and
materials that indicate they have (or are
certified as having) low-VOC content
or low-VOC emissions and follow
manufacturers' printed  instructions for
use.

Specify products and materials that
meet independent certification and
testing protocols, such as the following:

• California Department of Public
  Health, Emission Testing Method
  for California Specification
  01350, complying with the limit
  requirements for classrooms,
  regardless of space type
• Carpet and Rug Institute Green Label

EA 13.1 Air Out New Materials
Where possible, air out new materials in
a well-ventilated, clean and dry space
prior to installation. Off-site opening of
wrapped or tightly packaged materials
to facilitate this conditioning step is
also acceptable.

EA 13.2 Seal Composite Wood Products
Seal  composite wood  products (e.g.,
particle board, pressed wood) that
are not compliant with California
Title  17 Airborne Toxic Control Measures
(ATCM) or that do not meet Section 6.1
of EPA's Indoor airPLUS Construction
Specifications with a sealant intended
to reduce VOC emissions. Seal all
exposed surfaces and holes, as
appropriate. Check with vendors for
recommendations on sealing their
engineered wood products.

EA 13.3 Investigate and  Correct
Contaminant Source Problems After
Building Modifications
If odors or complaints indicate VOCs
or other airborne contaminants after
work has been completed,  remove any
potential sources (e.g., arts and crafts
materials,  fiberglass that may contain
formaldehyde) from the room or area.
If removal is not feasible, consider
installing local exhaust ventilation for
sources that are isolated  to a specific
room or area,  at least on  a  temporary
basis until materials off-gassing has
subsided.  If these actions do not
solve the problem (e.g., persistent
odors, occupant complaints), hiring an
environmental professional and testing
may be necessary.

               MA 13.2 Use Low-Emitting Wood and Composite-Wood Products
               When installing structural plywood or pressed or composite wood products,
               select those that are certified compliant with California Title 17 ATCM
               to reduce formaldehyde emissions from composite wood products.  If
               California Title 17 ATCM compliant materials are not available, use wood
               products that meet Section 6.1 of EPA's Indoor airPLUS Construction
               Specifications or composite wood products that contain no added
               formaldehyde.

               Notes
               •  California Title 17 ATCM regulations require reduced formaldehyde
                 emissions from composite wood products and finished goods that
                 contain composite wood products sold,  offered for sale, supplied,  used
                 or manufactured for sale in California.
               •  Title VI of TSCA sets national formaldehyde emission standards  for
                 composite wood products that are identical to California's Phase II
                 emission standards. EPA currently is developing the regulations to
                 implement these standards nationally.

               MA 13.3 Provide Adequate Ventilation
               Ensure that the school meets the Minimum Actions in  Priority Issues
               19.0 Outdoor Air Ventilation and 20.0 Exhaust Ventilation.

               MA 13.4 Post-Construction Flush-Out With Outdoor Air
               After construction is completed, ventilate the renovated building/spaces
               with the design outdoor air ventilation rates before occupancy resumes.
               Ensure that HVAC systems are operational and capable of adequately
               controlling indoor humidity levels during the flush out. Do not conduct
               a "bake-out" in an attempt to reduce VOC emissions after the building
               is occupied, because it may cause VOCs to be absorbed by other interior
               materials and may damage building components.
               If possible, follow the post-construction flush-out requirements specified
               in ASHRAE Standard 189.1, Section 10.3.1.4(b), which requires a total
               number of air changes corresponding to the ventilation system operating at
               its design outdoor air flow rate continuously, 24 hours  per day for 14 days.
               A longer flush-out period can be used if there are concerns or complaints
               about IAQ after the  initial flush out. Additional, periodic flush out may also
               be needed for spaces that have intermittent or infrequent occupancy and
               are not ventilated for extended  periods.

               MA 13.5 Limit VOC Absorption During Construction
               Follow guidance outlined in MA 22.3 to protect absorptive materials during
               construction.

               MA 13.6 Limit Children's and Other Occupants' Exposure
               Follow Priority Issue 22.0 Protecting IAQ During  Construction to protect

 Evaluate the condition of the existing
 HVAC system components in accordance
 with minimum  inspection standards of
 ASHRAE/ACCA Standard 180, ASHRAE
 handbooks, or other equivalent standards
 and guidelines.
 The HVAC assessment is to include
 an evaluation of whether the system is
 functioning properly,  based on ASHRAE
 and ACCA standards appropriate for
 the type of equipment. Determine
 whether the  HVAC system is properly
 sized  in accordance with ASHRAE  load
 calculation manuals and handbooks
 or other equivalent standardized
 guidelines. Evaluate building heating
 and cooling loads after planned
 modifications and HVAC equipment
 capacities for sensible and latent loads.
 If HVAC replacement  or modification is
 anticipated,  base sizing calculations on
 post-upgrade conditions.
 The assessment shall include the
 following:
 •  Inspect the air filters and
   filtration system for overall filter
   condition, filter efficiency, particle
   accumulation, filter blowout, and air
    leakage around filters.
 •  Inspect air plenums and ductwork for
    indications of  mold growth, excess
   dirt or obstructions. Determine
   whether components and systems
    installed in plenums (e.g., cables)
   are rated for use in plenum spaces.
 •  Inspect exhaust system for proper
   direction of fan rotation, corrosion,
   excessive vibration, blockage, or
   pressure differentials that can lead to
    leakage or flow reversals.
        MINIMUM ACTIONS (MA)
MA 18.1 Ensure Existing Systems Oper-
ate Properly
Based on an assessment of equipment
condition and sizing, repair, modify or
replace equipment to ensure proper HVAC
function and correct related deficiencies.
The ability to modify and adjust the
existing HVAC system may be limited
by its initial design. Review the original
equipment specifications and seek
outside engineering assistance as needed.
If maintenance, cleaning or repairs
are needed to restore the HVAC to
proper  functioning, perform them
in  accordance with ASHRAE/ACCA
Standard 180, ACCA Standard 6,
or  other equivalent standards and
guidelines. Ensure that there is a
scheduled inspection and maintenance
program for HVAC systems in
accordance with ASHRAE/ACCA
Standard 180.
For units with filter status pressure
switches, ensure that switches are
operating properly and scheduled for
regular calibrations.
When adjusting existing HVAC systems,
refer to Priority  Issues 19.0 Outdoor Air
Ventilation and  20.0 Exhaust Ventilation
for guidance on ventilation and exhaust
requirements.

of all cooling coils or other devices
with wetted surfaces (e.g., MERV 11 or
higher), if the new equipment is capable
of physically accommodating the
filters and has adequate fan capacity
to overcome the high-efficiency filters'
pressure drop.

EA 18.2 Increase Filter Efficiencies in
Existing HVAC Systems
For existing systems, check with the
manufacturer to determine whether
filters with higher MERV ratings can
be installed without introducing an
unacceptable increase in airflow
resistance. Install filters with the
highest MERV rating that can be
accommodated by the equipment.

cleaning strategies,  if appropriate, to
supplement pollutant source control
strategies  and  the performance of
the outdoor air ventilation system
in removing pollutants. Maintain
the prescribed minimum outdoor air
ventilation rates if this approach is
used (see  Priority Issue 19.0). Consider
the limitations of the air handling
system, the amount and severity of
contaminants, and  the features of the
filtration and air cleaning equipment.
Filtration and air cleaning strategies
may be advisable in the following
conditions:
• Outdoor air  often is polluted (e.g.,
  schools located near roadways) or
  consistently/seasonally burdened with
  high heat or humidity.
• Source  control tactics are insufficient
  or occupant activities generate high
  contaminant loads.
• Occupants require enhanced
  protection from contaminants.

      ASSESSMENT PROTOCOLS (AP)
 AP 19.1 Determine Compliance With
 ASHRAE Standard 62.1 Ventilation
 Requirements
 Based on existing design documents
 and balancing reports, or building
 audit results, determine whether the
 school complies with the ventilation
 requirements of ASHRAE Standard 62.1.
 This will require measuring airflows
 onsite.

 Note
 Some existing ventilation systems may
 not be capable of meeting the minimum
 outdoor air ventilation requirements
 of ASHRAE Standard 62.1 because
 of capacity limitations, whereas other
 existing ventilation systems may have
 sufficient capacity to meet or exceed
 the standard.
 ASHRAE Standard 62.1, Table 6.2.2.1
 provides minimum breathing zone
 ventilation requirements for various
 space types. The Ventilation Rate
 Procedure  requires that zone and
 system ventilation rates be calculated
 based on these minimum rates. Each
 ventilation zone and each system must
 meet the ASHRAE requirements for the
 building to be in compliance.
 Determine whether the ventilation
 system satisfies the requirements of
 ASHRAE Standard 62.1, Section 5 for
 Systems and Equipment.
        MINIMUM ACTIONS (MA)
MA 19.1 Adjust Existing Systems To
Meet ASHRAE Standard 62.1 Where
Possible
Adjust the ventilation rates of existing
systems to meet the requirements
of ASHRAE Standard 62.1, where
possible, using the Ventilation  Rate
Procedure.
If it is not possible to increase venti-
lation rates to meet the requirements
of ASHRAE Standard 62.1  because of
equipment capacity  limitations, building
space limitations,  budgetary constraints
or other reasons, the ventilation system
shall be adjusted to  provide the maxi-
mum outdoor airflow possible. The con-
ditions (e.g., heating and cooling loads)
for which the systems cannot meet
the ASHRAE Standard 62.1 require-
ments should be identified, and the
systems should be operated to meet the
ASHRAE Standard 62.1 requirements
whenever load conditions permit.

Note
ASHRAE Standard 62.1 also allows
a Natural Ventilation Procedure
in conjunction with mechanical
ventilation systems,  with a  few specified
exceptions. When natural ventilation
is provided, efforts should be made
to ensure that windows and other
ventilation openings are operated
appropriately.
Ensure compliance with Section 5
of ASHRAE Standard 62.1  wherever
possible.

MA 19.2 Consider Impacts of Building
Envelope Air Sealing on Ventilation
Avoid tightening the building
envelope to reduce air exchange
rates if mechanical ventilation  rates
are deficient. Ensure that school
buildings relying on  natural ventilation
will have adequate ventilation after
weatherization activities.
        EXPANDED ACTIONS (EA)
EA 19.1 Replace/Upgrade Existing Sys-
tems To Meet ASHRAE Standard 62.1
If existing systems cannot meet
ASHRAE Standard 62.1, upgrade HVAC
systems to obtain compliance or create

operable windows and other ventilation
openings are operated appropriately to
ensure adequate ventilation. This may
include monitoring indoor and outdoor
carbon dioxide levels and providing
visual feedback to building operators
and occupants.

EA 19.3 Apply Advanced Ventilation
Approaches
Apply advanced ventilation approaches
that have the  potential to reduce energy
use and  improve IAQ, including the
following methods:

•  Dedicated outdoor air systems
  (DOAS)

•  Demand-controlled ventilation
•  Displacement ventilation

•  Economizers

•  Energy recovery ventilation

• Variable-air-volume systems
If any of these ventilation strategies
are used, ASHRAE Standard 62.1
Ventilation Rate Procedure requirements
must be met under all  loads and
occupancy conditions.

MA 20.1 Provide Local Exhaust Where Needed and Meet
ASHRAE Standard 62.1 Exhaust Rates
Ensure exhaust is provided for rooms or areas with local-
ized indoor contaminant sources as identified in AP 20.1.
If ASHRAE Standard 62.1 exhaust requirements are not
met, repair, replace or install local exhaust ventilation to
meet the requirements, ensuring that ducts are sized, in-
stalled and vented properly to the outdoors. Seal exhaust
ductwork to improve performance and maintain  negative

Inadequate Exhaust
If there are occupant complaints related to inadequate ex-
haust (e.g., odors, moisture), ensure that the following are
operating properly:
•  Mechanical equipment, ducts and combustion flues are
   in good condition. Ducts are not subject to corrosion,
   blockage or excessive leakage.
•  There is no back draft from combustion flues under
   worst-case conditions.
•  Exhaust fans are drawing air and the air is coming out
   of exhaust vents on the roof at  the intended airflow
   rates.
•  Exhaust draws contaminants away from, rather than
   toward, occupants.
•  Exhausted room is under negative pressure relative to
   the surrounding spaces.
•  Exhaust system is turned on, outdoor air grilles and air
   dampers are operating properly, and adequate make-up
   air is provided.
•  Outdoor air dilutes contaminants from all sources. The
   ventilation system should provide sufficient outdoor air
   to all occupied spaces during all operating modes. See
   Priority Issue 19.0 Outdoor Air Ventilation.
•  Airflow patterns provide proper air mixing.
•  The exhaust system  is not subject to excessive vibration.

 ASSESSMENT PROTOCOLS
           (AP)
AP 22.1 Assess Occupan-
cy During Construction
Periods
Determine the nature
of building occupancy
during construction
periods. Identify the areas
of the building that will
be occupied. Identify
any special needs of
the building occupants
(e.g., elderly faculty,
young students, disabled
students and faculty).
Identify specific times
of occupancy. Identify
occupant complaints or
concerns.

AP 22.2 Identify Contami-
nants and Pathways
Identify potential
contaminant sources
from building upgrades
(e.g., activities, materials
and equipment that
have the potential to
cause IAQ problems) and
pathways through which
contaminants could affect
the air quality for the
building occupants.
                   MINIMUM ACTIONS (MA)
MA 22.1 Minimize Children's and Other Occupants' Exposures
During Upgrade Activities
When conducting activities that may result in exposure to
airborne contaminants (e.g.,  cutting or grinding materials,
painting, installing insulation) comply with local laws and adhere
to the Sheet Metal and Air Conditioning Contractors' National
Association's (SMACNA) Indoor Air  Quality Guidelines for
Occupied Buildings Under Construction.  Minimize children's and
other occupants' exposures to VOCs, particles or other airborne
contaminants by the following procedures:
•  Restrict building occupants and  workers without the personal
   protective equipment  needed for the work being performed
   from the construction area.
•  Separate construction areas from occupied portions of the
   building using appropriate containment and ventilation
   practices. Ensure that work areas are properly isolated (e.g., by
   constructing a sealed, rigid-wall  air barrier with a lockable door
   separating the work area from occupants or  isolating smaller
   work areas with a plastic sheeting air barrier). Ensure that work
   areas are ventilated with exhaust to the outdoors to protect
   workers and occupants. Contaminants should be captured as
   close as possible to the source of the emissions. Work areas
   should be under a negative pressure relative to surrounding
   spaces. Ensure that exhausted construction contaminants do
   not re-enter the building.
   Note
   If negative pressurization  in the  work areas  is not possible, use
   an exhausted double  wall buffer zone to separate work areas
   from surrounding areas.


•  Ensure fire egress requirements from occupied portions of the
   building are maintained when isolating work areas.
•  Do not conduct dry-sanding without implementing containment
   measures for the dust generated.
•  Ensure sufficient ventilation and cure time of wet-applied
   materials to protect occupants before re-entry into work area.
•  Establish vehicle staging areas for loading and unloading
   materials and equipment at  least 100 feet away from outdoor
   air intakes, operable windows and entryways to the building.
•  Clean the area thoroughly  before re-entry of unprotected
   workers or occupants to ensure removal of any dusts that may
   contain pollutants. Use sealed, HEPA-rated  vacuums.
•  Follow all manufacturers'  printed instructions, which  may
   indicate the need to evacuate building occupants and other
   unprotected individuals from work areas during and for some
   period after the use of a product.
•  Create specific plans to contain particulate matter during
   demolition activities.
•  Limit IAQ impact of airborne contaminants released  by roofing
   materials during installation (e.g., hot mop asphalt, seam
   sealing on EPDM, polyvinyl chloride or modified bitumen
   roofing).  Establish isolation barriers and keep roofing materials
   away from outdoor air intakes or  conduct pollutant-generating
   roofing activities during unoccupied periods.
•  Promptly respond to any occupant complaints or concerns.
    IPANDED ACTII
EA 22.1 Consider and
Implement Additional
Protections As Appropriate
For situations that the
assessment process
classified as relatively high
risk, consider implementing
the following options:
•  Require rigid-wall  air
   barriers with sealed,
   lockable entries between
  work areas and occupied
  spaces and  provide
   negative pressurization to
  contain contaminants.
• Create a buffer zone
  around work sites.
•  Restrict construction
  activities to off-hours
  when feasible.
• Conduct temporary air
  cleaning.
• Stage construction
  activities in controllable
  sizes.
• Control  pressurization
  and the indoor
  environment with
  temporary HVAC
  equipment.
• Vacate the entire
   building, when feasible.

                              Protect HVAC systems from contaminants during work activities.
                              • Seal openings in existing ducts located in work areas to avoid infiltration by dust
                                and debris.
                              • New HVAC equipment, ducts, diffusers and return registers should be stored in a
                                clean, dry place and should be covered to prevent dust accumulation.
                              • If operating an  HVAC system that interfaces with the work areas, ensure that the
                                system does not pull return air from the work area and  install air filters with a
                                MERV 8 rating or  higher during construction activities.
                              • Visually inspect duct work after construction activities have been completed and
                                clean internal surfaces as needed to remove dust and debris.
                              • Ensure that all filters used during work activities have been removed and that
                                new filters are properly installed before operating the HVAC system during
                                occupancy.

                              MA 22.3 Protect Highly Absorptive Materials
                              Protect any existing absorptive materials  in place by fully  covering with plastic
                              sheeting. Fully secure all edges of the sheeting to protect materials from airborne
                              contaminants and emissions caused by construction.

                              Schedule the  installation of absorbent materials—such as ceiling tiles, fabrics,
                              furnishings and carpet—after major dust  and  pollutant-generating activities are
                              completed. Ensure that materials have not been exposed to moisture and are  dry
                              before installation.

                              MA 22.4 Safely Install Spray Foam Insulation
                              Employ safe work  practices to avoid exposure to spray polyurethane foam (SPF).
                              Follow the manufacturers' printed instructions for vacating building occupants and
                              other unprotected individuals not involved in the application of the SPF products
                              from the premises during and for some period after SPF application. Require  and
                              confirm  SPF to be installed in strict accordance with manufacturer's requirements.

                              Note
                              The curing time (complete reaction) of SPF insulation varies depending on the type
                              of product, application technique, temperature, humidity and other factors. While
                              the SPF is curing it still contains unreacted chemicals, which include isocyanates
                              and proprietary chemicals. Manufacturers estimate that it can take approximately
                              1 to 3 days after application for the two-component high pressure "professional"
                              SPF system to fully cure and approximately 8 to 24 hours for the one-component
                              foam to  cure.  Exposure to isocyanates may cause skin, eye and lung irritation,
                              asthma, and sensitization. Exposures to isocyanates should be minimized. See
                              EPA's Spray Polyurethane Foam Web page for more information.

Project Planning
There are key steps during the building upgrade
process that can provide opportunities to reduce
costs and leverage synergies or,  if not addressed
adequately, can increase costs and lead  to future
challenges. These steps are outlined in Table Al:
                                 Project Planning, and are detailed in Section 2:
                                 Assessment Protocols and Recommended Actions
                                 of the Energy Savings Plus Health Guide. These key
                                 planning steps can dramatically influence a  project's
                                 direction, cost and outcomes and help maximize the
                                 impact of the Guide to help ensure a smooth project
                                 delivery.
Table Al: Project Planning
 Integrated Design
                                           Table A1: Project Planning
Collaboration during building improvement projects can allow teams to solve problems creatively
and with better outcomes for the building and for occupants than the traditional design and
construction process.
In an integrated process, project teams define the goals from the earliest stages of the project
planning and carry these goals through to building occupancy and the operations and maintenance
phases. Early engagement of all responsible parties avoids problems that occur when IAQ is treated
as an afterthought and allows for consideration of alternative design concepts that improve IAQ and
energy performance. Include an integrated design approach in the contract requirements for all
design, construction and commissioning  teams.
Refer to Priority Issue 1.0 Project Planning/Integrated Design for more information.
 Develop a Project Team
Create a strong project team that is committed to protecting IAQ throughout all phases of the
project, from pre-design through building occupancy and use.  Establishing a multidisciplinary team
at the beginning is important to reduce design errors and provide opportunities for collaboration.
A collaborative team will save the project time and money,  as well as ensuring that energy
consumption and  IAQ goals are addressed from the beginning.
Schedule regular full-team meetings to review design goals and collaboratively discuss challenges.
Ensure that a school representative is always present during project  meetings to ensure the overall
project goals are guiding factors in discussion and to answer any operations and maintenance
questions of the project team.
Refer to Table A2: Developing a Project Team for more details.
 Conceptualize the
 Project
As outlined in the Introduction of this Guide, IAQ is a critical component of school building
upgrades because air quality can seriously affect the health of building occupants, especially
children. During each energy upgrade or building renovation project, consider ways IAQ can be
improved and ways that the upgrades under consideration could positively or negatively affect IAQ.

                                               Table A1: Project Planning
 Complete Energy and
 IAQ Audits
An energy audit identifies ways to improve energy efficiency in a building. An IAQ audit, sometimes
referred to as an IAQ walkthrough inspection, identifies IAQ issues in a building that affect
occupant health and safety. Sometimes, when equipment upgrades or operational changes are
completed to improve energy efficiency, IAQ can be negatively affected. For example, performing
energy upgrade activities without considering building ventilation can  lead to decreased air quality,
condensation problems, or elevated humidity levels that can cause mold growth. The resulting
tradeoff for reduced operating cost from energy savings is decreased occupant health and safety.
By performing both energy and IAQ audits and including IAQ planning in energy improvement
projects, these potential negative effects can be mitigated while also taking advantage of the
synergies of energy efficiency and IAQ.
When planning for energy and IAQ audits, ask whether the energy auditor can assist an IAQ
professional, such as the school's IAQ coordinator, with an  IAQ assessment. Additionally, ask
the energy auditor whether the outdoor ventilation rates are sufficient and if the controls are
functioning properly, as ventilation plays a large role in both energy efficiency and IAQ.
Refer to AP 1.2 for more information on IAQ walkthroughs. Any final decisions regarding the
project scope and plan should be made after the walkthrough and should ensure that major IAQ
issues are accounted for and addressed.
 Identify Hazardous
 Materials
Hazardous materials such as lead, polychlorinated biphenyls (PCBs), asbestos and mold all pose
significant health and  safety issues to building occupants in old or even previously renovated
buildings. These materials must be identified prior to starting work to ensure safe construction
practices are used and that the materials are safely removed from the building as necessary.
Removing these  hazardous materials can be expensive, and any associated costs should be built
into the project budget during the initial planning stages.
Refer to the following Priority Issues for specific information regarding potential locations of these
materials within the building and for remediation guidance:
3.0 Moisture Control and Mold
4.0 Asbestos
5.0 Lead
6.0 Polychlorinated Biphenyls (PCBs)
 Test for Radon
Radon is a cancer-causing radioactive gas. It is odorless, colorless and tasteless, and it is a serious
health and safety issue that must be addressed early in  project planning. Measuring radon levels in
schools is a relatively easy and straightforward process compared to many other important building
upkeep activities. Mitigation of elevated radon levels can be more expensive, and any associated
costs should be built into the project budget during the  initial planning stages.
Refer to Priority Issue 7.0 Radon for testing and mitigation guidance.
 Design Charrette
Overall project goals, scope and systems-level strategy should be discussed during the
Design Charrette or planning meeting. During this meeting, designers, engineers, and school
representatives and decision makers should discuss strategy and synergies between IAQ and energy
efficiency that can be implemented to achieve overall project goals. The Charrette should be
concluded by outlining a defined project strategy. This strategy may include some "wish list"  items
that may later be ruled out based on cost; however, the goal of this meeting is to strategize tangible
methods to achieve a school's desires so that the facility manager and other school  decision
makers can make informed final decisions about project scope.
Refer to MA 1.1 for more information on the Design Charrette process.

 Owner's Project
 Requirements (OPR)
The OPR is a formalized document that describes the school "owner's" project goals and functional
requirements for how a building is designed and built. The OPR is a key document because design
and construction teams will refer to it to ensure that project requirements and goals are achieved
by design and construction decisions. In addition to the project design and construction team, the
Commissioning Agent also will use the OPR as a foundation for the commissioning process, which
also makes it integral to the quality assurance process.
Refer to MA 2.2 for more guidance and reference documents regarding the OPR.
 Commissioning
 Design Review/Quality
 Assurance During
 Design
Quality assurance checks are important to conduct during any building improvement project. Often,
quality assurance is completed through the commissioning process. Although small improvement
projects (e.g., minor system upgrades) may not warrant the cost of a full commissioning process
completed by an outside firm, large multisystem  projects (or projects providing improvements
throughout the building) can achieve great value from following a formalized commissioning
process. For these projects, a commissioning agent should be hired during the project's design
phase, and the agent should see the project through to completion to ensure that all systems
operate and  function according to their design intent and/or optimum performance level. For
small improvement projects, the system design and installation should at least be reviewed by a
competent party, such as a facility manager  or a  building engineer.
If a commissioning agent is hired, include contract requirements for at least one design review,
including drawings and specifications, to ensure  that quality assurance and commissioning
considerations are implemented during design. For small projects, the facility manager or other
qualified, unbiased party should perform this review.
Refer to MA 2.4 for more information on creating a commissioning plan.
 Construction Kick-Off
 Meeting
Prior to construction, conduct a kick-off meeting with the full team to discuss the OPR and all
applicable Priority Issues that will need to be considered for the project. Unifying the project team
prior to construction ensures that all team members have the same understanding of project goals,
requirements, priorities and expectations.
 Construction Planning:
 Protecting Occupied
 Areas From
 Construction Pollutants
If parts of the building will be occupied during the improvement project, ensure that the areas
under construction are isolated with appropriate pressure control to limit construction  dust and
other pollutants from impacting occupants. Even small improvement activities, such as wall
penetrations and touch-up painting, can generate indoor pollutants that lead to IAQ issues and
health concerns. Before beginning any demolition or improvement project, create a plan to
minimize contaminants from entering occupied buildings.
Refer to Priority Issue 22.0 Protecting IAQ During Construction. Additionally, refer to Appendix B:
Communication and Education, which includes information to communicate with occupants to
promote safety during construction.
 Retro-Commissioning
Retro-commissioning is a process of restoring existing systems to operate in accordance with their
design intent and/or at the highest performance level possible. Generally, retro-commissioning
focuses on energy-related systems, such as adjusting HVAC equipment and thermostat set points,
adjusting direct digital controls and/or building automation systems, reprogramming automatic
lighting controls, realigning daylight or occupancy sensors, rebalancing refrigerant levels,  and
recalibrating ventilation levels in each room. Repairing any operational issues and fine-tuning
system functionality will improve IAQ and occupant comfort, as well as energy and resource
efficiency. The need for retro-commissioning will be identified during a building energy audit, and
retro-commissioning activities can be performed  by an experienced commissioning agent.
For more information on building energy audits and retro-commissioning, refer to Priority Issue 2.0
Commissioning.
 Implementing Jobsite
 Safety
Assessing and implementing Jobsite safety is important to protect visitors to the site and those
performing work on the building. To minimize exposure to health and safety risks on the Jobsite,
see Appendix C: Worker Protection.

Table Al: Project Planning (continued)
                                             Table A1:  Project Planning
 Testing and
 Balancing and Onsite
 Commissioning
On completion of building construction and systems installations, onsite commissioning
takes place to test, verify and fine-tune the performance of the newly installed systems.
Onsite commissioning typically takes from one to several days. Often, the commissioning
agent conducting the tests will  find installation issues to address. Make sure to work with
the commissioning agent to build time and resources into the project schedule for onsite
commissioning and for addressing any issues found by the commissioning agent's inspection.
Fixing systems outlined in the commissioning agent's issues log can delay projects,  but taking
action to fix any  problems prior to occupancy will improve cost-effectiveness, reliability and
long-term performance.
 Building Flush-Out
To flush out all workspaces properly with outdoor air prior to occupancy, build additional time into
the project completion schedule. The total recommended flush-out time varies depending on the
project size and often ranges from 2 weeks to a full month to complete. Some period of flush-out
time  is better than none.
Refer to MA 13.4 and EA 13.4 for more information.
 Project Turnover and
 Systems Training
Working with a commissioning agent from the early planning phases can help to ensure that the
building operates at the highest possible level of energy performance while meeting IAQ goals. In
the commissioning agent's contract, require the development of comprehensive operations and
maintenance training and systems manuals so that building operations and maintenance staff can
keep the building functioning at the highest performance level.
Refer to MA 2.8 and EA 2.3 for more information.
 Solicit Continuous
 Feedback
Building occupants (e.g., school administrators, building planning management teams, teachers,
health and safety staff, custodial staff, and students) are a great resource for identifying IAQ and
energy efficiency concerns because they use and work in the building every day. These activities
can promote occupant satisfaction in the long term:
•  Educate building occupants about the types of issues that could affect IAQ.
•  Create a clear process for building occupants to submit feedback and concerns.
•  Encourage schools to implement EPA's "IAQ Tools for Schools" program actions, if they are not
   already doing so.
See Appendix B: Communication and Education.
Developing a Project Team

An integrated design approach  is a drastic change
from traditional design and construction practices.
Traditionally, each discipline—such as the architect;
mechanical,  electrical, plumbing and civil engineers;
and the construction team—would work independently.
During planning and design, the architect often would
lead the work by creating the overall building layout
and then pass the design on to the engineers, who
would all work independently. This type of process can
create major design errors that  go unchecked until
the construction team tries to implement the design.
A traditionally organized design team does not nec-
essarily have a meeting with the construction team
                                  to review the project goals. Even  if the design team
                                  understands that energy efficiency is extremely import-
                                  ant to the school, this information may not be relayed
                                  to the construction team,  which may make installation
                                  or purchasing decisions that  it thinks are equivalent
                                  to the design but in the end do not meet the project's
                                  goals. Table A2: Developing a Project Team outlines
                                  who should be involved during each phase of the proj-
                                  ect to maximize collaboration, reduce the potential for
                                  misunderstandings and meet the goals of the project,
                                  which first and foremost prioritizes a healthy and pro-
                                  ductive indoor environment for children, teachers and
                                  all who use the school  building.

                           Appendix B:  Communication  and  Education
Renovation and construction projects in a school create
unique challenges that affect the design and construc-
tion processes and the occupancy phase after work is
complete. This appendix provides strategies for effec-
tive, proactive and responsive communications to help
maintain a healthy and productive school indoor envi-
ronment before, during and after a building upgrade.
It also is vital to ensure staff receive adequate training
on operations, maintenance and repair after energy
retrofits and  building upgrades. Providing education
to school faculty, staff and students about the IAQ
goals of each project and information related to proper
operation and occupancy can help to ensure that the
renovated building and its systems continue to work
as intended.  This education reduces costs and risks
to the overall project and the design and renovation/
construction  teams. This appendix outlines information
about the project that should be provided to school
facility managers, staff and students.

Effective Communications
Effective communications can help to prevent IAQ
problems and allay unnecessary fears. In addition,
schools should respond  promptly and effectively to
any IAQ issues that may arise. Effective, proactive
and responsive communications are a critical, ongo-
ing process for maintaining IAQ in the school. Com-
munication can help school occupants understand
how their activities affect IAQ, which will enable
them to improve their  indoor environment through
proper choices and actions.

Proactive Communication
Schools and  school  districts can reap many benefits
from taking a proactive approach to addressing IAQ is-
sues. The positive public relations that can result from
this approach can lead to a better understanding of
IAQ by school occupants and the community. Commu-
nicating effectively, both  internally and externally, is a
key element.
Build rapport with the local media now. An informed
media aware of your efforts to prevent IAQ problems
and that understands the basics of IAQ in schools can
be an  asset instead  of a liability during an IAQ crisis.
Communicating the goals of the IAQ Management
Plan to those within the school—teachers, custodians,
administrators, support staff, the school nurse,
students—is  key. The following steps can help develop
good communication between you  and the school
occupants:
1.  Provide accurate information about factors that are
    affecting IAQ.
2.  Clarify the responsibilities and activities of the IAQ
    coordinator.
3.  Clarify the responsibilities and activities of each
    occupant.
4.  Notify occupants and parents of planned activities
    that may affect IAQ.
5.  Employ good listening skills.
The necessary level of communication often depends
on the severity of the IAQ complaint. If the complaint
can be resolved quickly (e.g., an annoying but harm-
less odor from an easily identified source) and involves
a small number of people, communication can be
handled in a straightforward manner without risking
confusion and bad feelings among school occupants.
Communication  becomes a more critical issue when
there are delays in identifying and resolving the prob-
lem and when serious health concerns are involved.
Step 4 deals with informing occupants  and parents
before the start of significant planned activities
that produce odors or contaminants. If occupants
and parents are uninformed, they may become
concerned about unknown air contaminants, such
as strange odors or excessive levels of dust, and
register an IAQ complaint. Examples of planned
activities include pest control,  painting, roofing and
installation of new flooring. Notification of planned
activities also can prevent problems from arising
with students and staff with special needs. For
example, an asthmatic student  may wish to avoid
certain areas within a school, or use alternative
classrooms, during times when a major renovation
project will produce higher levels of dust. A sample
notification letter is provided in the model painting
policy on the EPA IAQ Tools for Schools website.
Step 5 involves effective listening. School occu-
pants often can provide  information that helps
prevent problems, and being "heard" may help
defuse negative reactions by occupants if indoor air
problems develop.

Responsive Communication
When an IAQ problem occurs, you can be assured
that the school  community will  learn about it quick-
ly. Without open communication, any IAQ problem
can become complicated by anxiety, frustration and
distrust. These complications can increase both the
time and money needed to resolve the problem.
               Energy Savings Plus Health I  INDOOR AIR QUALITY GUIDELINES FOR SCHOOL BUILDING UPGRADES

-------
Immediate communication is vital and is easiest if a
few strategic steps are taken before an IAQ problem
arises.  First, ensure that a spokesperson is ready by
having  a working understanding of the communica-
tion guidance found in this section and a background
knowledge of IAQ as outlined in EPA's IAQ Tools for
Schools IAQ Reference Guide. This  person should also
have complete access to information as the investi-
gation  progresses. Because of these qualifications,
the school's IAQ coordinator may be a good choice for
spokesperson. Second, establish a plan for how you
will communicate to the school community. The school
community includes all occupants of the school,
parents, the school district administration  and school
board,  the local union, and the local news media.
Paying attention to communication when solving a
problem helps to ensure the support and cooperation
of school occupants as the problem  is investigated and
resolved. There are basic,  yet important, messages to
convey:
  • School administrators are committed to providing
    a healthy and safe school.
  • Good IAQ is an essential component of a healthy
    indoor environment.
  • IAQ complaints are taken seriously.
When a problem arises, communication should begin
immediately. You should not wait until an investigation
is nearly completed or until final data are available
before  providing some basic elements of information.
Communications,  whether in conversations or in writ-
ing, should include the following elements in a factual
and concise manner:
  • The general nature of  the problem, the types of
    complaints that  have been received, and the loca-
    tions that are affected;
  • The administration's policy in regard to providing a
    healthy and safe environment;
  • What has been done to address the problems or
    complaints, including the types of information that
    are being gathered;
  • What is currently being done, including factors
    that have been evaluated and found not to be
    causing or contributing to the problem;
  • How the school community can help;
  • Attempts that are being made to  improve  IAQ;
  • Work that remains to be done and the expected
    schedule for its completion;
  • The name and telephone number of the IAQ coor-
    dinator, who can be contacted for further  informa-
    tion or to register complaints; and
  • When the school will provide the next update.
Productive relations will be enhanced if the school
community is given basic progress reports during the
process  of diagnosing and solving problems. It is advis-
able to explain the nature of investigative activities, so
that rumors and suspicions can be countered  with  fac-
tual information. Notices or memoranda can be posted
in general use areas and delivered directly to parents,
the school board, the local union, and other interested
constituents of the school community. Newsletter arti-
cles, the school website or other established commu-
nication channels also can be used to keep the school
community up to date.
Problems can arise from saying either too little or too
much. Premature release of information when  da-
ta-gathering still  is incomplete can cause confusion,
frustration and future mistrust. Similar problems can
result from incorrect representation of risk—improperly
assuming the worst case or the best.  If even simple

Energy Savings Plus Health I  INDOOR AIR QUALITY GUIDELINES FOR SCHOOL BUILDING UPGRADES

-------
progress reports are not given, however, people will
think either that nothing is being done or that some-
thing terrible is happening.
Even after the  problem  is correctly diagnosed and a
proper mitigation strategy is in place, it may take days
or weeks for contaminants to dissipate and symptoms
to disappear. If building occupants are informed that
their symptoms may persist for some time after solving
the problem, the inability to bring instant relief is less
likely to be seen as a failure.
Remember to communicate after problem-solving;
although you may know that the problem has been
resolved, the school community may not know, so be
sure to provide a summary status report. The figure
below summarizes the main steps for responsive com-
munications.
  Communication Principles
  • Be honest, frank and open. Once trust and
    credibility are lost, they are almost impossible
    to regain. If you do not know  an answer or are
    uncertain, say so. Admit mistakes. Get back to
    people with answers. Discuss data uncertainties,
    strengths and weaknesses.
  • Respect your audience. Keep explanations
    simple, avoiding technical language and jargon
    as much as possible. Use concrete images that
    communicate on a personal level. People in the
    community often are more concerned about such
    issues as credibility,  competence, fairness and
    compassion than about statistics and details;
    however, provide sufficient information to audi-
    ences that are capable of understanding more
    technical explanations.
  • Employ your best listening skills. Take time to
    find out what people are thinking, rather than
    assuming that you already know.
  • Tailor communication strategies to your
    audience. Use mass  media for providing informa-
    tion and interpersonal techniques for changing
    attitudes.
  • Involve school employees. An informed staff is
    likely to  be a supportive staff.
  • Involve parents. Inform parents about what is
    being  done and  why, as well as what will happen
    if problems  are detected.
  • Involve the school board. Encourage board mem-
    bers to observe the process (e.g., taking a walk
    through the school with the IAQ coordinator).
 • Involve businesses that provide services to the
   school (e.g., exterminators, bus fleet administra-
   tors/operators) and businesses located around the
   school, which may also negatively affect IAQ.
 • Emphasize action. Always try to include a discus-
   sion of actions that are underway or that can be
   taken.
 • Encourage feedback. Accentuate the positive and
   learn from your mistakes.
 • Strive for an informed public. The goal  is for the
   public to  be involved, interested, reasonable,
   thoughtful, solution-oriented and collaborative.
 • Be prepared for questions. Provide background
   material on complex issues. Avoid public conflicts
   or disagreements among credible sources.
 • Be responsive. Acknowledge the emotions that
   people express and respond in words and actions.
   When in doubt, lean toward sharing more infor-
   mation, not less,  or people may think you are
   hiding something.
 • Combat rumors with facts. For example, set up a
   chalkboard in the teachers' lounge or in anoth-
   er general use area for recording what is heard.
   Record rumors as they arise and add responses.
   Then pass out copies to the staff.
 • Do not overpromise. Promise only what  you can
   do and follow through with each promise.
 • Work with the media. Be accessible to reporters
   and respect deadlines.  Try to establish long-term
   relationships of trust with  editors and reporters.
   Remember that the media are frequently more
   interested in  politics than  in science, more in-
   terested in simplicity than complexity, and more
   interested in  danger than  safety.

Priority IAQ Concerns and IAQ Considerations
After the Building Upgrade

This section is organized by IAQ concerns (e.g., mois-
ture control, asbestos, lead), in the same order as in
the Assessment Protocols and  Recommended Actions
of Section  2 of this Energy Savings Plus Health Guide.
Each IAQ concern is  broken down  into two columns:

  • Health Effects and Potential Exposure Locations:
    This column explains how each IAQ concern can
    negatively affect  health and identifies common
    locations within schools where the priority IAQ
    concern may be found. It also points to the appro-
    priate Priority Issue(s) for further reading.

       Exposure Locations
Health Effects
Mold exposure can both cause
and exacerbate respiratory-related
health issues, such as allergic re-
actions and asthma.

Potential Exposure Locations
Mold can grow in any area with
long-term moisture exposure,
including exposure from large
spills, equipment overflows or
plumbing leaks; leakage through
roofs, windows or openings in the
building envelope; seepage from
improperly sloped sites; or spaces
with high humidity, such as locker
rooms, crawlspaces and basement
storage areas.

                Considerations After the Building Upgr
Regular Inspections
School staff should regularly inspect bathrooms, locker rooms, science
laboratories and other rooms with high humidity levels or potential for
condensation or plumbing leaks.

System and Building Operations
Operate the HVAC system and use additional dehumidification if neces-
sary to keep relative humidity levels below 60%, ideally between 30%
and 50%, if possible. Relative humidity levels above 60% can create
an environment conducive to mold growth.
Indoor air can become too dry for occupant comfort and health during
the heating season, particularly in northern and high-altitude locations.
Ensure the regularly scheduled maintenance of humidification equip-
ment and controls installed  to maintain a low relative humidity limit
(e.g., 30%). Improperly maintained humidification equipment can lead
to microbiological  problems.

Administrator and Staff Education
The EPA course  "Introduction to Mold and Mold Remediation for En-
vironmental and Public Health Professionals" provides an overview of
mold prevention and  mold remediation. It is based on EPA's voluntary
guidance document "Mold Remediation in Schools and Commercial
Buildings."  Public health and environmental health professionals who
are involved with mold issues may be interested in this course. Building
managers, custodians, remediators, contractors and other professionals
who respond to mold problems also may want to refer to this course.

Occupant Feedback
Ensure that school administrators, staff and students know whom to
notify if they see spills, leaks, condensation, or other signs of standing
moisture or moisture damage.
Complaints of musty odors also may indicate moisture or condensation
issues and should  be investigated.

Student Education Opportunities for Teachers
Teach students about the link between mold and moisture and the as-
sociated health risks.  See EPA's Teacher Resources and Lesson Plans
website for a link to the educational material, "Hold the Mold."

Health Effects

PCBs have been shown to cause a
variety of adverse health effects,
including effects on the immune
system, reproductive system, ner-
vous system  and endocrine sys-
tem in animals. PCBs also have
been shown  to cause cancer in
animals. Studies in  humans pro-
vide supportive evidence for the
potential carcinogenic and non-
carcinogenic effects of  PCBs.c

Potential Exposure Locations

PCBs were manufactured domes-
tically from 1929 until  1979,
when  EPA banned the processing
or use of PCBs, except  in totally
enclosed equipment.11

PCBs can  be found  in older build-
ings in fluorescent light ballast
capacitors and potting material,
electrical transformers, window
caulking, rubberized paint formu-
lations, and  soil near the building.

Regular Inspections
If PCB-containing ballasts were not replaced as part of the building
improvement project, inspect them regularly for any signs of wear or
damage.
System  and  Building Operations
Intact, operational  ballasts may not pose a health risk or environmen-
tal hazard; however, given that PCB-containing ballasts have not been
manufactured domestically since 1979, the typical life expectancy of
magnetic fluorescent light ballasts (10 to 15 years) has been well
exceeded.6
Also, PCB-containing ballasts may lack thermal overload protection,  in-
creasing the possibility of fires or leaks. The hazard can be worsened if
the ballasts are mishandled by personnel who are unaware of the pres-
ence of  PCBs in the lighting ballasts.
Administrator and Staff Education
Ensure that teachers and administrators understand where PCB-
containing ballasts are  located so they can warn the facility manager of
damage.
Student Education Opportunities for Teachers
Educate students about PCBs. See EPA Fact Sheets for Schools and
Teachers About PCB-Contaminated Caulk. Also see EPA's
PCB-Containing Light Ballasts Web page.

Health Effects
In the United States, radon is
the  leading cause of lung cancer
among nonsmokers and the sec-
ond-leading cause of lung cancer
overall (after smoking), account-
ing  for 21,000 deaths annually.'
Potential Exposure Locations
Radon is a naturally occurring,
radioactive component in soil
gas that enters buildings through
floors and walls that are in con-
tact with the ground. For schools,
EPA recommends radon testing
for all frequently occupied rooms
in contact with the ground.
Further Reading
Priority Issue 7.0 Radon
Regular Inspections
The only way to determine whether schools have elevated radon levels
is to perform radon testing.
If radon mitigation strategies were implemented for the school, periodi-
cally check to ensure that radon mitigation systems are operating prop-
erly and that ventilation systems are providing the required amount of
outdoor ventilation air. Biennial retestingfor radon should be performed
in all areas of the schools that have been mitigated.
Student Education Opportunities for Teachers
Educate students about the health effects of  radon. See EPA's Teacher

Volatile Organic Compounds
(VOCs) from gasoline compo-
nents (benzene); dry cleaning
and degreasing solvents, such as
perchloroethylene and trichloro-

cause cancer in animals; some
are suspected or known to cause
cancer in humans and have been
associated with birth defects.8
Petroleum hydrocarbons in soils
can be caused by spills or leaks
from oil and fuel storage tanks
commonly associated with gas
stations or fuel storage tank sys-
tems and piping.

Petroleum hydrocarbons include
many compounds, each having
different  health effects. Health ef-
fects can include headaches and
dizziness from airborne exposure;
numbness in the feet and legs;
and various effects on the blood,
immune system, lungs, skin and
eyes."
Metals: Although low background
levels of  metals may not repre-
sent a health concern, elevated
levels of some metals in soil are
frequently encountered across the
country, particularly in urban ar-
eas, and  some (such as mercury)
can form a hazardous vapor.
Potential Exposure Locations

Belowground contaminants can af-
fect soil and groundwater, both of
which can allow contaminants to
enter buildings via direct seepage
or vapor migration through build-

Vehicle
Exhaust
    Health Effects and Potential
       Exposure Locations
Health Effects
With sufficient concentrations and
duration, pollutants from vehicle
exhaust may increase the chance
of cancer or other serious health
effects. Diesel exhaust specifically
can aggravate respiratory and car-
diovascular disease and  existing
asthma. It also can cause acute
respiratory symptoms, chronic
bronchitis and decreased lung
function, all of which children are
more susceptible to.
Potential Exposure Locations
Exhaust emissions come from
vehicles such as school buses,
cars, delivery trucks, and motor-
cycles, as well as from equipment
used for construction and grounds
maintenance.
Vehicle exhaust emissions can
affect indoor health when these
outdoor contaminants migrate in-
doors, as may occur when vehicles
idle during student drop-off and
pick-up or when HVAC outdoor air
intakes are  located near vehicle
idling zones, drawing exhaust
emissions into the building.1

             IAQ Considerations After the Building Upgrad
System and Building Operations
Consider strategies to reduce exhaust emissions (e.g., purchase clean-
ing equipment that does not have gas-powered engines).
Consider no- and low-cost adjustments to limit exhaust emissions
exposure:

•  Institute anti-idling policies for school buses and parents.

•  Consider the way buses currently queue for pick-up and drop-off to
   determine whether engine runtime can be reduced while buses wait
   for students to board.

•  Do not open windows near loading and unloading zones and consid-
   er moving loading zones so they are at least 25 feet from windows,
   doors and outdoor air intakes.
Administrator and Staff Education
Promote alternative transportation options outlined in IAQ Tools for
Schools.  For example, "school-pooling"  programs encourage carpools,
bike  partners or "walking school buses" that reduce the number of vehi-
cles on school grounds. Public transit buses may also be an appropriate
option for some students or staff.
Student and Parent  Education
       Signage Opportunity: Remind parents that vehicle emissions
       can affect their children's health.
       Example Text: "Vehicle exhaust can trigger asthma attacks and
       other respiratory symptoms. Please, do not idle your vehicle
       while waiting."
       Sign Locations: Within sight of drop-off  and pick-up zones.
       Signage Opportunity: Remind students where it is safe to wait
       for buses and other rides home.
       Example Text: "Waiting Zone. Please wait here for your ride so
       you don't breathe in harmful vehicle exhaust."
       Sign Locations: Locate in a safe waiting zone, at least 25 feet
       from areas with operating vehicles.

should be followed.
Administrator and Staff Education
Ensure that teachers, staff and school nurses are aware of air quality
advisory days. During air quality advisories, children should  not play
outside and may experience respiratory symptoms. The AirNow  School
Flag Program also can be used to alert school  staff to the local air qual-
ity forecast and help them to take actions to protect students' health,
especially those with asthma. School staff also can  become  involved
with local ozone "watchdog" groups and review school  practices to help

Pests           Health Effects

                Risks arise from pests and ex-
                posure to pesticides in school
                settings. Diseases may be trans-
                mitted by biting insects. Asthma
                attacks may occur from allergens
                or triggers from cockroach and
                rodent infestations. Staff and
                students may be unnecessarily ex-
                posed to pests and pesticides.

                Potential Exposure Locations

                Rodents, cockroaches, termites,
                birds, bats and other pests can  be
                found in school buildings. Pests
                prefer warm, dry spaces with easy
                access to food and water.

Regular Inspections
Many tactics that prevent pest problems and pest-conducive conditions
also contribute to water and energy conservation, indoor air quality, cost
reduction and  asset preservation. For example, effective door sweeps
can reduce pest complaints by 65%, reduce infiltration of dirt and
prevent escape of heat and conditioned air. Repairing leaking pipes
prevents pest access to moisture and also reduces water consumption
and costs.
In-house or contracted professional pest manager should conduct a
comprehensive inspection of all buildings for defects, including cracks,
crevices and other pest entryways; food, moisture and shelter resources
available to pests;  moisture, pest or other damage  to structural  ele-
ments; termite earthen tunnels, pest  fecal  matter or other signs of pest
activity; and so forth. The report of all defects should identify corrective
actions. The inspection should be mapped on the site and floor plan.
Use a written Integrated Pest  Management (IPM) inspection checklist
or form for periodic inspections, listing each building feature (e.g.,
foundation, eaves) and room to be inspected, including specific loca-
tions within features or rooms (e.g., vents,  storage closets) to be includ-
ed in the inspection, and specific conditions to be noted  (e.g., repair,
cleaning needs).
Maintain legible records of inspection results, pest management actions
and evaluations of results; keep these records for at least 3 years.
Establish a timeline for completing corrective actions and evaluating
results.
System and  Building Operations
Schools should implement IPM tactics that include prevention, inspec-
tion, communication,  biopesticide use, and judicious and careful use
of pesticides when necessary. When a pest professional is needed, your
school or school district may choose to have its IPM program certified
or recognized.  When seeking IPM certification, look for a widely rec-
ognized program that provides assistance in developing, maintaining,
sustaining and evaluating your IPM program. Educate facility managers
about IPM through training, brochures and other appropriate guidance.
Occupant Education
       Ensure that all school  occupants are notified well in advance of
       pesticide applications on school grounds and in the local area.
       Signage Opportunity: Post signs prior to pesticide use to notify
       school  occupants.
Note
Many states have notification  laws when pesticides are used.
Example Text:  "Pesticides will be used in this area on [date]. Do not
walk in this area between [application date] and [safe contact date, per
manufacturer printed directions]."
Sign Locations: Space signs at regular intervals around pesticide appli-
cation  area.  Before applying pesticide, mark off entire application area
with yellow caution tape. Unless absolutely necessary, pesticides should
not be applied when students are present on campus.
Occupant Feedback
Provide a simple process for school administrators, staff and students
to notify the facility manager if they see signs of pest infestations. Many
schools use pest logs to record pest sightings; these logs often are
located in the  teachers' lounge.
Student Education Opportunities for Teachers
Educate students about IPM.  See EPA's Teacher Resources and Lesson
Plans Web page for links to resources on IPM.

    Health Effects and Potential
       Exposure Locations
Health Effects
Combustion pollutants result from
the burning of fuels and other
materials. Common combustion
pollutants include carbon monox-
ide (CO), nitrogen dioxide (N02)
and respirable particulate matter
(PM).
CO is a colorless, odorless gas.
Symptoms of  CO exposure may
mimic influenza and include
fatigue,  headache, dizziness,
nausea and vomiting, cognitive
impairment, and tachycardia. At
high concentrations CO exposure
can be fatal.
N02 is a colorless, odorless gas
that causes eye, nose and throat
irritation; shortness of breath; and
an increased risk of respiratory
infection.
Health effects of respirable PM
include eye, nose, and throat
irritation; respiratory infections
and bronchitis; asthma; and lung
cancer.
Potential Exposure Locations
CO results from incomplete oxi-
dation of carbon  in combustion
processes. Potential CO sources
include  improperly vented fur-
naces or combustion applianc-
es, malfunctioning gas ranges,
and exhaust fumes that have
been drawn back into the build-
ing. Worn, improperly adjusted
or poorly maintained combustion
devices (e.g.,  boilers, furnaces),
or a flue that  is improperly sized,
blocked, disconnected or  leaking,
can be significant sources. Auto,
truck or bus exhaust from at-
tached garages, nearby  roads or
idling vehicles in parking areas
can also be sources.
Sources of N02 and respirable PM
include  unvented or improperly
vented combustion equipment,
fireplaces, wood stoves and kero-
sene heaters,  and diesel exhaust.

Regular Inspections
Maintenance staff should perform regular inspections of combustion
appliances and associated venting systems, as well as of carbon mon-
oxide detection and warning equipment, to ensure that equipment is in
good condition and operating properly.
System and Building Operations
Combustion equipment must be maintained to ensure that there are no
blockages, and air and fuel mixtures must be  properly adjusted to en-
sure complete combustion.
If the school has carbon monoxide detection and warning equipment,
follow manufacturer calibration recommendations to make sure that
they are working properly. Additional ventilation  can be used as a tem-
porary measure when elevated levels of CO are experienced for short
periods of time.
Occupant Education
       Signage Opportunity:  Educate occupants on the importance of
       CO detection and warning equipment.
       Example  Language: "Carbon monoxide (CO) is a colorless, odor-
       less gas that can cause headaches, dizziness, disorientation,
       nausea and fatigue at low levels of exposure. At higher concen-
       trations, CO exposure can be fatal. If this CO alarm provides
       a warning for a high CO level, vacate the room and notify the
       facility manager and school  nurse immediately."

Administrator and Staff Education
Federal regulations (20 USC Section 6083) prohibit smoking within any
indoor facility owned or leased or contracted for and used for provision
of routine or regular kindergarten, elementary or secondary education or
library services to children. State or local laws may be more restrictive.
Urge teachers, administrators and staff to make the school's tobac-
co-use policy a priority. The policy must be consistent with local and
state laws and should include prohibitions against tobacco use  by stu-
dents,  all school staff, parents and visitors on school property; in school
vehicles; and at school-sponsored functions away from school property.
Occupant Education
       Signage Opportunity: Remind occupants and visitors of  the

    Health Effects and Potential
       Exposure Locations
Health Effects
Poorly designed or maintained
HVAC systems can exacerbate IAQ
problems. For example, moisture
can accumulate in ducts leading
to mold growth, incorrectly in-
stalled or maintained filters can
allow particulates to be spread
throughout the building, and sys-
tems that do not provide enough
outdoor air ventilation can result
in high levels of indoor pollutants,
often  as indicated by elevated in-
door carbon dioxide  levels, which
is considered a surrogate for other
indoor pollutants. This will con-
tribute to occupant dissatisfaction
and can cause headaches, dizzi-
ness,  nausea, poor concentration,
lethargy and reduced student
performance. Inadequate indoor
thermal control also can negative-
ly affect student performance.
HVAC Opportunities
Among the main purposes of an
HVAC system are to  help main-
tain good IAQ through adequate
ventilation and filtration and
to provide thermal comfort and
indoor moisture control. HVAC
systems are among the largest
energy consumers in schools. The
choice and design of the HVAC
system can also affect many other
high-performance goals, including
water consumption (water-cooled
air conditioning equipment) and
acoustics.
Engineers can design a quality
system that is cost-competitive
with traditional ventilation de-
signs  while successfully providing
an appropriate quantity and qual-
ity of  outdoor air, lowering energy
costs, allowing for easier main-
tenance, and  improving student
performance.

Create a maintenance schedule for the HVAC system to ensure that fil-
ters are changed regularly and any calibration requirements are met.
System and Building Operations
If HVAC systems are upgraded or improved during the construction
project, the contracting team must provide thorough, onsite training
to the facility management staff to ensure systems can be operated
properly. Facility managers are encouraged to pay special attention to
the sequence of operations, any direct digital controls or building auto-
mation systems, and  the outdoor air ventilation rates that the system is
designed to provide to each room. When natural ventilation  is provided,
efforts should be made to ensure that windows and other ventilation
openings are operated appropriately to ensure adequate ventilation.
Occupant Feedback
Provide a system for school  occupants to comment on perceived indoor
air quality, thermal comfort, humidity levels, standing water or leaks,
and air speed, as these issues can be indicators of HVAC calibration or
operational problems.

Mercury        Health Effects
               Mercury is a neurotoxic substance
               that can produce a wide range of
               health effects in children depend-
               ing on the amount and timing of
               exposure. Elemental (metallic)
               mercury primarily causes health
               effects when it is inhaled as a va-
               por and absorbed into the lungs.
               Potential Exposure Locations
               Mercury is used in many items

Appendix  C:  Worker Protection

Priority Issue 23.0 Jobsite Safety of the Energy
Savings Plus Health Guide refers to this appendix for
worker protection. This appendix contains information
to help those performing and supervising the building
upgrade assess the risks to workers; it recommends
actions to minimize risks to workers' health and safety
and identifies resources for additional information.
Worker protection is especially important in older
buildings. Areas  undergoing construction may con-
tain remnants of legacy contaminants, such  as lead
and asbestos. Although these materials often are not
considered harmful  if left undisturbed or covered, they
can become a concern when disturbed. Therefore,  it is
essential that the contractors review available informa-
 tion about the existence of such materials before be-
 ginning any modifications to the building.  If existence
 of hazardous materials is suspected, a review must
 be commissioned by the school authorities. In some
 situations, only certified personnel can  perform certain
 activities  outlined in this Guide.
 By law, employers and supervisors are required to
 provide workers with a workplace that is free from
 recognized hazards  that are causing or are likely to
 cause death or serious physical harm, as required in
 Section 5(a)(l) of the Occupational Safety and Health
 Act of 1970. Employers and supervisors must ensure
 the following:
1. Work site operations are conducted in compliance with Occupational Safety and Health Administration (OSHA) reg
  ulatory requirements. OSHA regulatory requirements identify the following construction hazards to be addressed:
 Asbestos-Containing Materials

 Chemical Hazards

 Confined Spaces

 Electrical

 Falls

 Ladders

 Lead

 Personal Protective Equipment
29 CFR Part 1926.1101 and 40 CFR Part 763, Subpart G

29 CFR Part 1926.1053

29 CFR Part 1926.62 and 40 CFR 745

29 CFR Part 1926.28
2. Workers are trained in the hazards of their job and the methods to protect themselves.
3. Workers are provided the protective equipment needed to reduce site exposures.  Employers are required to
   perform a Personal Protective Equipment Hazard Assessment for each employee.
Table 01 provides a list of recommended assessments
and actions for worker safety concerns.  Project contract
documents (drawings or specifications)  and site plans
should include precautions to address these issues.
Table 01 also includes measures an employer needs to
take to evaluate existing and potential health concerns
and recommended actions to ensure worker safety.
Assistance with  developing these worker protection
plans often is available from state or federal training
programs. OSHA offers training courses and educational
programs to help broaden worker and employer knowl-
edge on the recognition, avoidance, and prevention of
safety and health hazards in their workplaces. OSHA
also offers training and educational materials that help
businesses train their workers and comply with the Oc-
cupational Safety and Health Act (see http://www.osha.
gov/dte/i ndex.html).
 When known pollutants are being produced or disturbed
 during retrofit activities, follow appropriate standards
 (including OSHA, National Institute for Occupation-
 al Safety and Health [NIOSH] and EPA standards) to
 minimize worker and occupant exposure. The document
 "IAQ Guidelines for Occupied Buildings Under Con-
 struction" published by the Sheet Metal and Air Con-
 ditioning Contractors' National Association (SMACNA)
 also can be  used as a best-practices manual for main-
 taining  IAQ  in occupied buildings undergoing renovation
 or construction. The SMACNA document covers how to
 manage the source of air pollutants, control measures,
 quality control and documentation, and  communication
 with occupants.

Table Cl:  Recommended Assessments and Actions for Worker Safety Concerns
                        Asbestos
 Assessment: Determine whether workers will be exposed to
 ACM. Because of the predominant use of ACM, construc-
 tion and renovation activities in older schools may expose
 workers to this hazard. The Asbestos Hazard  Emergency
 Response Act (AHERA), a provision of the Toxic Substanc-
 es Control Act, became law in  1986. AHERA requires
 local education agencies to inspect their schools for ACMs
 and prepare management plans to prevent or reduce
 asbestos hazards, often known as an AHERA asbestos
 management plan.
 Actions
 •  Comply with the ACM  in Schools Rule at 40 CFR
    Part 763, Subpart E and the OSHA rule at 29 CFR
    Part 1926.1101, which provides the required protec-
    tion measures for work involving ACMs.
 •  See OSHA's website on asbestos for additional
    information and resources.
                    Chemical Hazards
 Assessment: Determine whether workers will be exposed to
 chemical hazards' by chemicals in use, accidentally
 released by actions taken (e.g., spills from mercury-
 containing lamps or ballasts), or contact with pre-existing
 chemically contaminated building materials, subsoils or
 vapors.
 Actions
 •  Comply with the OSHA rule at 29 CFR Part
    1910.1200, which includes the following requirements
    (not an exhaustive list):
     o that chemical content  information be made
       available for all chemicals in use;
     o that containers be properly labeled; and
     o that workers handling chemicals be properly
       informed and trained.
 •  Use chemicals that are best-in-class for the  particular
    application in terms of having low toxic content and/
    or low contaminant emissions. Examples include
    paints,  adhesives, sealants and coatings that meet the
    emissions criteria of California Department of Public
    Health Specification 01350.
 •  Proper health and safety precautions should be
    employed by workers who use or may come in contact
    with pesticides or chemical contaminants in building
    materials, subsoils or vapors.
 •  For pesticides, comply with EPA's 40  Code of Federal
    Regulations  Part  170—Current Agricultural Worker
    Protection Standard (includes all amendments as of
    Octobers, 1997).
 •  See OSHA's website on chemical hazards

   Ensure the work space is cleaned regularly and has ad-
   equate ventilation and exhaust and that construction is
   phased properly to protect workers and occupants from
   construction activities that are considered high risk,
   as outlined in SMACNA "IAQ Guidelines for Occupied
   Buildings Under Construction," 2nd Edition.
   Under OSHA rule at 29 CFR Part 1926.21 (b)(6)(i),
   inform all employees required to enter confined or
   enclosed spaces about the following:
    o the nature  of the hazards involved;
    o the necessary precautions to be taken;  and
    o the use of required protective and emergency
      equipment.
   See OSHA's website on confined spaces for additional
   resources on confined space hazards in general industry.

   Poisoning" Quick Card for additional information on
   sources of CO and recommended actions for preventing
   CO exposure.
   See Priority Issue 13.0 Building Products/Materials
   Emissions and  EPA's Design for the Environment
   Program website for more information on selecting
   less toxic  products and materials that may be used in
   confined spaces.
Assessment: Determine whether the work will generate
dust. Use best-practice measures to manage and control
air quality contaminants in areas of work.
Actions
•  Educate workers about dust containment procedures
   and  how to control dust and debris created by equip-
   ment used in construction activities.
•  Use work methods that minimize dust and prevent dust
   from spreading to other areas of the school.
•  Isolate areas where work is being performed (e.g.,
   sealed with plastic sheeting) to contain any dust that is
   generated during construction activities.
•  Remove all classroom furniture from the work area or
   cover furniture with plastic sheeting to prevent dust
   contamination.
•  Turn off forced-air, central heating and air-conditioning
   systems (including local, window air conditioning units)
   while work that creates dust is being completed.
•  Collect and remove all construction  debris.
•  Conduct a careful cleanup routinely and at the end of
   the project.
•  See  OSHA's websites on wood dust, combustible dust,
   and  permissible exposure limits for additional  informa-
   tion  and resources.
I. Based on 29 CFR Part 1926.59, a chemical hazard is a chemical that is either a physical hazard or a health hazard. "Physical hazard" refers to a chemi-
  cal for which there is scientifically valid evidence that it is a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer,
  pyrophoric, unstable (reactive) or water-reactive. "Health hazard" refers to a chemical for which there is statistically significant evidence based on at least
  one study conducted in accordance with established scientific principles that acute or chronic health effects may occur in exposed employees.

Table Cl: Recommended Assessments and Actions for Worker Safety Concerns (continued)
                        Electrical
 Assessment: Determine whether workers will be exposed to
 electrical hazards.
 Actions
 •  Follow OSHA rule 29 CFR Part 1926, Subpart K
    requirements for protecting workers from electrical haz-
    ards (not an exhaustive list):
     o Employers must make sure that all non-double-
       insulated electric equipment is equipped with a
       grounding conductor (three-wire type).
     o Worn or frayed electric cords must not be used.
     o Employers must provide either ground-fault circuit
       interrupters or an assured equipment grounding
       conductor program (which includes the regular
       testing of all equipment grounding conductors) to
       protect employees from ground faults.
 •  See OSHA's Electrical Incidents E-Tool for additional
    information  on electrical safety.
 Assessment: Determine whether workers will be required to
 work at heights of 6 feet or more.
 Actions
 •  If work is required at heights of 6 feet or more, protect
    workers with guard rails or by properly securing to pre-
    vent falls.
 •  See OSHA rule at 29 CFR Part 1926.501 for additional
    information on requirements.
 •  See OSHA's Web page on fall  protection and OSHA's
    Falls E-Tool for additional  information on protecting
    workers from fall hazards.
 Assessment: Determine whether workers will be using ladders.
 Actions:
 •  Follow OSHA rule at 29 CFR Part 1926.1053, which
    includes the following requirements (not an exhaustive
    list):
    o  Portable  ladders must be able to support at least
       four times the maximum intended load.
    o  Ladders that must lean against a wall are to be
       positioned at a 4:1 angle.
    o  Ladders are to be kept free of oil, grease, wet paint
       and other slipping hazards.
    o  The area around the top and bottom of the  ladder
       must be kept clear.
    o  Ladders must not be tied or fastened together to
       provide longer sections.
    o  Metal ladders must not be used while working on
       electrical equipment and electrical wiring.
 •  See the OSHA rule at 29 CFR Part  1926.1053 for
    additional information on requirements.
 •  See OSHA's publication, "Stairways and  Ladders: A
    Guide to OSHA Rules," for additional resources on
    ladder safety.
Assessment: Determine whether project activities will ex-
pose workers to lead dust according to the Assessment
Protocols outlined in the Priority Issue 5.0 Lead. The most
common lead hazards in schools are lead-based paint
(especially in  pre-1978 buildings), lead dust and con-
taminated soil. Other sources of lead hazards are older
plumbing fixtures, vinyl miniblinds, painted toys and furni-
ture made before 1978, lead smelters, or other  industrial
sources.
Actions
•  If the facility was built before 1978, the existing
   paint is assumed to contain lead, and retrofitting
   or renovation activities must comply with EPA's
   Renovation, Repair and Painting Program  Rule (40 CFR
   Part 745) and the OSHA rule at 29 CFR Part 1926.62.
   See EPA's EPA Renovation, Repair and Painting
   Program  Rule website for additional information.
•  See OSHA's publication, "Lead in Construction," for
   information on OSHA requirements to protect workers
   from lead hazards in the construction industry.
Assessment: Determine whether workers will be exposed to
mold.
Actions
•  All suspected moldy areas should be remediated
   by properly trained individuals. Moisture problems
   need to be identified and fixed or mold will return.
   If mold is expected to be disturbed during activities,
   immediately bring this to the attention of the site
   manager and refer to OSHA's "A Brief Guide to Mold
   in the Workplace," NIOSH's "Recommendations for
   Cleaning and Remediation of Flood-Contaminated HVAC
   Systems: A Guide for Building Owners and  Managers,"
   EPA's "Mold Remediation in Schools and Commercial
   Buildings," the American Conference of Government
   Industrial Hygienists' "Bioaerosols Assessment and
   Control," the American Industrial Hygiene Association's
   "Recognition, Evaluation, and Control of Indoor Mold,"
   or the Institute  of Inspection,  Cleaning and Restoration
   Certification's S520 "Standard and Reference Guide for
   Professional Mold Remediation."
•  See EPA's Molds and Moisture website for additional
   information on  mold and mold remediation.

Table Cl: Recommended Assessments and Actions for Worker Safety Concerns (continued)
             Polychlorinated Biphenyls (PCBs)
 Assessment: Determine whether workers may be handling
 PCB-containingor PCB-contaminated building materials,
 including fluorescent light ballasts and caulk.
 Actions
 •  See EPA's PCB-Containing Fluorescent Light Ballasts
    in School Buildings Web page for information on
    proper maintenance, removal and disposal of PCB-
    containing fluorescent light ballasts. If leaking ballasts
    are discovered, wear protective clothing including
    chemical-resistant (nitrile) gloves, boots and disposable
    overalls.
 •  See EPA's PCBs in Caulk—Steps to Safe Renovation
    and Abatement of Buildings That Have PCB-Containing
    Caulk website for information on this topic. Work
    practices to help ensure worker and occupant safety
    include employing protective measures (both interior
    and exterior), complying with occupational protective
    regulations, communicating with building occupants/
    third parties, setting up the work area to prevent the
    spread of dust, using appropriate tools that minimize
    the generation of dust/heat, and leaving the work area
    clean.
            Spray Polyurethane Foam (SPF)
Assessment: Determine whether workers will be using SPF,
which may contain chemicals such as isocyanates (e.g.,
methylene diphenyl diisocyanate), amines, flame retar-
dants and/or other additives. There are three main types
of SPF products (two-component high pressure, two-
component low pressure, and one-component foam), each
of which has different applications.  Determine which of
the three main types of SPF products will be used.
Actions
• Applicators, crew and building occupants in the work
  area are required to use protective equipment to pre-
  vent exposure to isocyanates and other SPF chemicals.
   Protective equipment requirements vary depending on
  the type of SPF product.
•  Review label and product information for ingredients,
   hazards, directions, safe work practices and precau-
  tions.
•  Ensure  health and  safety training is completed and safe
  work practices are  followed to prevent eye, skin and in-
   halation exposures during and after SPF installation.
•  Exercise caution when determining a safe re-entry time
  for unprotected occupants and workers based on the
   manufacturer's printed recommendation. If you experi-
  ence breathing problems or other adverse health effects
  from weatherizing with SPF, seek immediate medical
  attention.
• See OSHA's Green  Job Hazards website for additional
   information on the hazards associated with SPF.
• See EPA's SPF website for additional information.
• See the American Chemistry Council's SPF Health and
  Safety website for additional information.

                                 Section 4:  Master Verification  Checklist
The core technical component of Energy Savings Plus
Health: IAQ Guidelines for School Building Upgrades is:
Section 2: Assessment Protocols and Recommended
Actions.
Section 3 contains appendices that are referenced
throughout the Guide.
Section 4 contains a Master Verification Checklist
to help verify that the assessment protocols in Sec-
tion 2 have been applied and that the appropriate
actions to protect or enhance IAQ have been taken
during the building upgrades. The checklist is a
valuable tool  for keeping track of progress during
the  building upgrade, including accomplish-
ments and upcoming issues to be addressed.
Alternatively,  the "Energy Saving Plus Health Check-
list Generator" tool can be used to develop a cus-
tom verification checklist, along with the  specific
assessment protocols and recommended  actions,
tailored to the building upgrade project. When using
the Energy Saving Plus Health Checklist Generator
it may be necessary to enable macros for function-
ality, depending on the users' Excel settings.
  Use the "Energy Saving Plus Health
  Checklist Generator"' To Create Your  Custom
  Verification Checklist, Assessment Protocols
  and Recommended Actions
Note
All checklists are complementary to the material pre-
sented in Section 2 and should be used in conjunc-
tion with the assessment protocols and recommended
actions. Section 2 should be thoroughly reviewed be-
fore verifying the protocols and recommended actions
on the checklists.
