1.1 Home Improvement Expert

The DOE launched the Home Improvement Expert (HIE), an easy way for homeowners to get a quality
job for energy equipment replacement and other retrofit projects. Homeowners can leverage expert
recommendations from the Department of Energy to help ensure quality installations by attaching HIE
checklists to vendor contracts and only accepting the work after vendors complete and sign the
checklists. The HIE has five new fact sheets for homeowner indoor air quality (IAQ) upgrades: three
whole-house ventilation strategies, bath exhaust fan, and kitchen exhaust fan. Approximately 40
manufacturing, big box, and financing partners have joined the program to promote this content to
consumers. Here is the website: basc.pnnl.gov/home4mprovement-expert.

Building America Program New Home IAQ Study continues. Broadly, the study seeks to characterize
IAQ and factors that impact IAQ in new homes built to current codes, including those with and without
mechanical ventilation.

The University of Central Florida presented details of the internal moisture generation moisture balance
approach to the ASHRAE 160 (Criteria for Moisture-Control Design Analysis in Buildings) project
committee at the ASHRAE annual meeting in Kansas City, Missouri, in June. The University made a
presentation with preliminary IAQ results for the Florida Environmental Health Association conference
in July and did again at the Energy and Environmental Building Alliance conference in October.

1.5 A DOE demonstration project by enVeried Won the Product of the Year award at the 2019 Air-
Conditioning, Heating, Refrigerating (AHR) Expo

The 2019 AHR Exp is the world's largest, most comprehensive gathering of over 70,000 HVAC industry
professionals from around the globe each year. Legacy commercial HVAC designs rely on massive
volumes of outside airflow to maintain indoor air quality, resulting in oversized equipment and often a
30-50 percent waste in HVAC energy consumption. To eliminate this waste, enVerid's HVAC load
reduction technology cleans a building's indoor air at a nanoscopic molecular level, enabling the building
to use far less outside air ventilation while improving indoor air quality. Buildings can then invest in
smaller, less expensive HVAC systems and realize immediate capital cost savings while enjoying 20-
30 percent ongoing annual energy savings for the life of the building. The key to the approach is low-
cost scrubbing of all gas contaminants from indoor air using novel, efficient and regenerable sorbent
materials to scrub the air.

This paper provides meta-analyses of the published findings relating the respiratory health of occupants
of schools with visible dampness, water damage, visible mold, and/or mold odor. Eleven studies, all with
cross-sectional designs, were included in the meta-analyses; however, analyses for some health
outcomes were based on as few as four studies. These meta-analyses and the published literature not
included in the meta-analyses suggest that dampness and mold in schools are associated with adverse
respiratory health effects.

This study is intended to demonstrate the potential for energy savings while providing acceptable IAQ
for zero net energy homes. It uses the concept of smart ventilation, where ventilation systems are
designed and controlled to produce the same, or better, IAQ compared to simple, continuously
operated ventilation systems. The key energy saving principle for smart ventilation is that ventilation is
shifted in time to when the energy required to condition the air is lower. A variety of smart ventilation

controls based on outdoor temperature, occupancy and auxiliary fan sensing were developed and
assessed across homes built to the 2016 Title 24 Prescriptive standards in California climate regions.
Computer simulations were used. On average, the smart controls reduced occupant pollutant exposure
by 0-10 percent, and they increased ventilation rates by roughly 20 percent. Occupancy-based controls
that accounted for contaminants released by building materials and furnishings during unoccupied times
were generally ineffective, with very low energy savings. Performance was improved somewhat through
use of a 1-hour pre-occupancy flush out period, though savings were still marginal compared to
temperature-based controls.

The following text is adapted from the article cited below:

LBNL developed and simulated the energy performance of smart ventilation controls based on outdoor
temperature in homes located in California climate regions, designed to comply with the 2016 Title 24,
Part 6 California Energy Code prescriptive requirements. The smart controls shift ventilation rates in
time, but ensure an annual occupant pollutant exposure equal to, or less than, what would be
experienced in a home with a constant ventilation rate. Computer simulations were conducted.
Controller performance varied substantially by climate zone, airtightness and house prototype. The best
controls averaged about one-third of ventilation-related energy savings that increased to about 48-55
percent. The vast majority of site energy savings were for heating end-uses (>90% of total savings).
Whole house ventilation rates increased between 0 and 42 percent, with typical increases in the 15-20
percent range.

NIST Net-Zero House

Project Contact: Lisa Ng, 301-975-4853, lisa.na@nist.gov

The NIST Net-Zero Energy Research Test Facility (NZERTF) is a two-story, four-bedroom house
incorporating energy-efficient construction, space conditioning systems and appliances, as well as solar
water heating and solar photovoltaics to meet the house's energy needs. For general information on the
house, view the following video: www.youtube.com/watch?v=xSzu83fyQaCl. All publications can be
found at the NIST NZERTF web page: www.nist.gov/el/nzertf/. Studies on thermal performance of the
small duct, high velocity distribution system as compared to a conventional air-to-air heat pump have
been completed in collaboration with Hyojin Kim, Ph.D., at The Catholic University of America. A report
on that work will be released this fall. Presentations will also be submitted to Indoor Air 2020 to be held
in Seoul, Korea, from July 20-24. A tracer gas system that measures both SF6 and C02 has been installed
in the home in order to obtain continuous air change rate measurements and conduct C02 injections for

investigation of demand-controlled ventilation and other control approaches. Plans for installing a C02
heat pump water heater and a geothermal heat pump are underway.

Do-lt-Yourself (DIY) Spray Polyurethane Foam (SPF) Application

Project Contact: Dustin Poppendieck, 301-975-8423, dustin.poppendieck@nist.gov

A DIY SPF application was performed in the NZERTF to replace removed SPF during system upgrades. A
study was performed to determine if EPA SPF ventilation guidelines are applicable to a DIY SPF
application event. Airborne and settled flame retardant concentration data showed that polyethylene
sheet enclosures may not completely isolate the SPF application area, but in this application with
adequate exhaust ventilation, they did protect the rest of the building from the flame retardant. A
summary of this work was recently published in Building and Environment
(doi.org/10. lQ16/i.buildeny.2Q19.Q4.Q33).

Cigarette Butt Emissions

Project Contact: Dustin Poppendieck, 301-975-8423, dustin.ooooendieck^nist.gov

Globally, around five trillion cigarette butts are disposed of per year. The U.S. Food and Drug
Administration (FDA) has regulatory authority over cigarettes and associated waste. FDA funded an
interagency agreement with the National Institute of Standards and Technology (NIST) to conduct an
investigation into airborne emission of non-smoldering cigarette butts. The FDA-funded effort examined
over 1,600 butts to determine (1) the initial distributions of emitted target chemicals in the cigarette
butt and (2) the influence of environmental parameters (temperature, relative humidity, aqueous
saturation, UV, and airflow rate) on airborne emissions. Further work examining 500 butts (funded by
NIST) was done to determine airborne emission rates for target chemicals from cigarette butts in a
simulated indoor environment. Both efforts demonstrated non-smoldering butts can be a significant
source of airborne chemicals, including nicotine. Two journal papers that summarize this work have
been submitted.

Real-Time Outdoor Air Infiltration Rates

Project Contact: Lisa Ng, 301-975-4853, lisg.ng@nist.gov

NIST has completed a Cooperative Research and Development Agreement (CRADA) with the National
Center for Healthy Housing, and Beetle Management, Inc., titled "Determination of real-time infiltration
rates in homes using low-cost sensors." The objective of this collaboration was to investigate the use of
air pressure sensors to estimate real-time infiltration rates in a home, in part to control mechanical
ventilation systems. The development of such a method is intended to overcome some of the challenges
and limitations that exist with tracer gas methods for determining infiltration rates. NIST conducted a
series of tracer gas tests at the Indoor Air Quality Test House and the NZERTF on the NIST campus. Using
the data and a detailed multizone airflow model of the home, NIST and the CRADA partners developed a
simplified model of the house that can be used to estimate real-time air infiltration rates. The report can
be found here: doi.org/10.6Q28/NlST.TN.2Q46.

ASHRAE Standard 189.1

Project Contact: Andrew Persily, 301-975-6418, andvD@nist.gov

The 2017 version of ASHRAE/ICC/IESUSGBC SSPC 189.1, Standard for High-Performance Green Buildings
Except Low-Rise Residential Buildings, was approved for publication late last year and includes 75
individual revisions to the 2014 version. The standard constitutes the technical content of the 2018
International Green Construction Code, which was just published late in 2018 and is available from the
International Code Council and ASHRAE. Standard 189.1-2017 itself will only be available outside of the
U.S. and Canada per an agreement between AIA, ASHRAE, ICC, IES and USGBC. In the area of indoor
environmental quality, revisions that have been incorporated into the 2017 standard (and therefore the
2018 IgCC) include a restriction on the indoor use of unvented combustion devices, a requirement for
occupant surveys to assess satisfaction with indoor environmental quality, and improvements to lighting
quality through daylighting and glare control.

The committee holds monthly web meetings, which are open to all interested parties. More information
on the 189.1 committee activities can be found on the ASHRAE website, where you can sign up for
notifications of public reviews and other information at www.ashrae.org/resources-publications/free-

sector, general public). A variety of federal agencies and departments (EPA, CPSC, DOE, National
Institute for Occupational Safety and Health (NIOSH), Occupational Safety and Health Administration
(OSHA), others) co-chair CIAQ, which holds public meetings roughly every 6 months to exchange
information on air quality-related issues and projects. Some recent federal updates have included
emerging technologies (additive manufacturing), occupancy and air quality-related sensor technologies,
smart ventilation, building for energy efficiency and good IAQ, the home microbiome and IAQ, school
IAQ, and IAQ policies (including those for radon). CIAQ participants respond to stakeholder questions
and provide updates on issues. Agency updates and notes are posted on the EPA website after each
meeting.

Participating in CIAQ allows CPSC the benefit of interacting with other federal agencies and
stakeholders. In addition, CPSC can communicate with other federal agencies on ongoing projects, such
as 3D printers, nanomaterials, mold and wearable technology. The CIAQ also enables the coordination
of efforts to address subject matter that multiple federal agencies oversee that is of interest to CPS.
Examples include—

1. Working with the NIST and NIOSH on several projects on nano and 3D printers.

2. Cosponsoring with stakeholders through the National Nanotechnology Coordination Office
(NNCO) a series of conferences on "Quantifying Exposure to Engineered Nanomaterials (QEEN)
from Manufactured Products."

3. Working with EPA to complete the evaluation of nanomaterial release from engineered
nanomaterial.

4. Contracting with the University of Cincinnati on nano and mold projects.

Nano Materials

Project Contact: Joanna Matheson, 301-987-2564, jmatheson(Sicpsc.gov

The University of Cincinnati is performing a follow-up study to the TERA literature review on three
nanomaterials of interest. The University of Cincinnati is reviewing recent literature (2016-2019), filling
in data gaps, and determining the appropriate dose metrics for in vivo and in vitro studies for nano
silver, nano titanium dioxide, and carbon nanotubes. The University of Cincinnati is also performing a
literature review on the emerging nanomaterials nano alumina, nano cellulose, and graphene. Final
reports are expected by September 2020. The University of Cincinnati is also starting a literature review
on the applications and uses of Fire-Retardant (FR) nanomaterials in consumer products and the
potential for consumer exposure.

We continue to work on projects with NIOSH, EPA and NIST:

• NIOSH is—

o Completing the evaluation of nanomaterials in and released from laser printers and the
potential toxicity of the released materials. Multiple publications have been produced from
these studies, including www.ncbi.nlm.nih.gov/pmc/articles/PMC4791579 and
www.ncbi.nlm.nih.gov/pmc/articles/PMC4749083.

o Continuing a multiyear project that will assess toxicological responses to aerosolized emissions
from Fused Deposition Modeling (FDM) 3D printers.

¦	The Phase 1 study consisted of characterizing emissions from ABS, PLA, and polycarbonate
filaments with and without multiwalled carbon nanotubes (MWCNTs); designing and
constructing a 3D printer exposure system for in vitro and in vivo exposure studies; and
performance of the in vitro studies. A manuscript was recently accepted for publication for
the in vitro results; these studies consisted of exposing human small airway epithelial cells
to 3D printer emissions to investigate cytotoxicity, apoptosis, and oxidative stress and
inflammatory markers.

¦	The Phase 2 studies are continuing with a focus on characterizing emissions from ABS and
PLA filaments with other types of engineered nanoparticles (other than MWCNTs);
developing a high-throughput emission generation method for toxicology studies, optimized
for inhalation exposure; investigating pulmonary and microvascular responses, liver toxicity,
neurotoxicity, as well as the biodistribution and biopersistence of emissions, after inhalation
of PC filament emissions in rats; evaluating responses in a murine experimental model of
asthma; and, evaluating the toxicological effects on the reproductive system after exposure
to PC filament emissions in vitro using commercially available human placental cells.
Initiating a project in collaboration with the EPA that evaluates several 3-D printers during
operation and during feedstock recycling tasks to understand factors that influence release
of emissions. Specifically, the aims of this project are to evaluate the influence of FFF 3-D
printer design, FFF feedstock filament; and recycling plastics to make filament and FFF 3-D
printing with recycled filaments.

• EPA is—

o Completing the evaluation of nanomaterial released from engineered nanomaterial (ENM)

surface coatings applied to outdoor surfaces and assessing the effect that aging may have on the
release of nanomaterials from the treated surfaces. Publications on this work include

www.ncbi.nlm.nih.gov/pubmed/30903905.www.ncbi.nlm.nih.gov/pubmed/28938214 and

o Continuing a multiyear collaborative project with NIOSH on characterizing commercially
available and commonly purchased FDM filament materials and quantifying the composition
and release of organic and inorganic chemicals and materials from FDM printer filaments, waste
and printed objects.

¦	The Phase 1 work involved compositional characterization of commercially available FDM
filament materials; the compositional characterization of particulate and gaseous/aerosol
elements released during the FDM printing process (e.g., identifying the size distribution,
agglomeration, chemical content, metal content, nanoparticles/nanotube content-
identifying VOCs and SVOCs and emission rates); and, the accumulation and composition of
particulate matter in areas adjacent to the FDM printer during and after operation will also
be assessed.

¦	The Phase 2 studies are commencing that will include identification of post-print processing
procedures for various FDM filament materials; compositional characterization of products
and/or waste materials created from the printing process as well as substances released

New Updates

There are no new updates since the last update (delivered August 15, 2018). We continue to work on
the projects with a plan for evaluating the effectiveness of PGMA and UL voluntary standards.

Previous Update (August 15, 2018)

In November 2016, the CPSC voted to approve a notice of proposed rulemaking (NPR) to reduce the risk
of carbon monoxide (CO) poisoning deaths and injuries associated with portable generators.

• The proposed rule limits portable generators' CO emission rates.

• The proposed rule's CO emission rates, which are technically achievable using existing and proven
emission control technologies that are already in the marketplace, are expected to lower the CO
emission rate from that of current generators by nominally 90 percent.

• The Federal Register (FR) notice with information about the proposed rule is available at

www.federalregister.gov/documents/2016/ll/21/2016-26962/safetv-standard-for-portable-
generators.

• The comment period closed April 24, 2017.

• The comments can be viewed by going to www.regulatioiis.gov and typing CPSC-2006-0057 on the
search line.

Staff also have been participating in development of voluntary standards to address the hazard:

• On January 24, 2018, UL announced that UL 2201 has received ANSI approval,
o This standard has requirements for—

•	On April 20, 2018, in a separate voluntary standard by the PGMA, G300 standard Safety and
Performance of Portable Generators also received ANSI approval.

o This standard has a requirement for a CO-sensing shutoff system that will shut the generator off
when CO concentrations around the generator reach either of the following at a location l"-2"
above the approximate center of the top surface of the portable generator

¦	Instantaneous reading of 800 ppm

¦	Rolling 10-minute average of 400 ppm

•	Staff has an interagency agreement with NIST to estimate the effectiveness of the CO hazard
mitigation requirements in these standards. The plan for this evaluation is published in NIST TN 2048
(available online at dx.doi.org/10.6028/NIST.TN.2048). It was open for public comment from July 9
to Sept 9, 2019. CPSC and NIST are evaluating the comments and will revise the plan as appropriate
before executing the plan. An additional report was published the same time as the plan, NIST TN
2049 (available online at dx.doi.org/10.6Q28/NlST.TN.2Q49). This report documents testing that was
done on generators that were shutoff using the shutoff criteria in both voluntary standards.

approximately $6.4 million was awarded under the Healthy Homes Technical Studies Grant Program to
seven institutions (see abstracts below).

1. Healthy Homes Technical Studies Grant Awards

1.1 The George Washington University researchers will study the impact of federal housing assistance
on residential environmental exposures. Prior research from the study team suggests housing assistance
programs are important social and health policy tools since housing assistance is associated with
improved physical and mental health for children and adults. However, it is unclear which attributes of
housing assistance are contributing to improved health. This study investigates the impact of HUD
housing assistance on exposure to indoor environmental contaminants such as lead, secondhand
tobacco smoke, and pesticides. This will be accomplished through extensive analysis of a unique dataset
that links HUD administrative data (1999-2016) with those from the National Health and Nutrition
Examination Survey (1999-2016). The research also includes the development of a housing
environmental quality index using American Housing Survey data.

Principal Investigator: AmiZota, Sc.D.

HUD Contact: Veronica Helms, Veronica.E.Helms(a)hud.gov

1.2 The National Center for Healthy Housing, partnering with the University of Illinois Indoor Climate
Research and Training Institute, will study the effectiveness of the installation of kitchen range hoods to
reduce moisture and gas stove generated levels of N02 and other contaminants compared with the
effectiveness of bath fans, the latter being the more common approach to achieving compliance with
ASHRAE Ventilation Standard 62.2, in 120 single-family homes undergoing weatherization. The main
objective of the study is to offer evidence-based guidance to homeowners, energy and housing
programs, and policy makers on how to improve indoor air quality in homes with gas stoves in a cost-
effective manner. The researchers will use information about building tightness to control for the effects
of energy efficiency measures, which could affect infiltration rates and contaminant levels. The study
will also track the costs of the bathroom ventilation systems as compared to the kitchen exhaust hoods.

Principal Investigator: Jonathan Wilson, iwilson(a)nchh.org
HUD Contact: J. Kofi Berko, J.Kofi.Berko(a)hud.gov

1.3 The University of Massachusetts Lowell researchers will study the effectiveness of portable high-
efficiency air filtration units in improving indoor air quality and reducing asthma symptoms and
healthcare utilization among 100 older adults (age 55+) with asthma living in smoke-free public or other
federally assisted housing. The research will be conducted in units with gas stoves, which are known to
emit contaminants that can trigger asthma. Using a stepped wedge design to evaluate the impact of this
intervention separately and in combination with the improvements seen with the typical multifaceted
educational and environmental interventions, the study will fill a major knowledge gap by measuring
both PM and N02 concentrations in homes that cook with gas stoves and document the reductions in
both pollutants when using HEPA/activated charcoal air purifiers. The study will gather data on the
effectiveness of air purifiers, as well as document changes in respiratory health measures following the
air purifier intervention. The potential benefit of adding subsequent standard multifaceted
environmental and educational interventions will also be assessed.

1.4	The University of Illinois Chicago researchers will (1) identify predictors of water lead levels in tap
water of homes with private wells, and (2) characterize the cost and efficacy of interventions to reduce
tap water lead in homes with private wells. Few states have any regulations to test well water for lead
content. UIC will generate information to inform prioritization of homes with private wells for water
lead testing. A pilot study suggests that age of home, water corrosivity, plumbing composition, and well
composition and condition may be predictors of lead in the tap water of homes with private water wells.
They will also generate information on the costs and efficacy of three different approaches to removing
lead from tap water of homes with private wells. Partner organizations include the Illinois Association of
Groundwater Professionals, Illinois Department of Public Health, Champaign-Urbana Public Health
District, Jackson County Health Department, Kane County Health Department, Peoria City/County Health
Department and the Whiteside County Health Department.

1.5	The Illinois Institute of Technology researchers will investigate the effectiveness of stand-alone air
filtration for improving indoor air quality (IAQ) and chronic obstructive pulmonary disease (COPD)
outcomes in a high-risk urban cohort of 80 U.S. military veterans with COPD. Additional secondary goals
of the study are to (1) investigate housing-related factors that may contribute to COPD exacerbation,
(2) investigate the utility of using low-cost sensors for indoor air pollution epidemiology studies and for
providing actionable or useful information on the quality of their indoor air to patients and their
physicians, and (3) evaluate the costs and benefits of using stand-alone air filtration to improve IAQ and
COPD outcomes. Participants will be recruited from the Jesse Brown Veterans Affairs Medical Center
(JBVAMC) through the West Side Institute for Science and Education (WISE) using a community-based
participatory process in which stakeholders, including patients, physicians, and local nonprofits, will
assist in the development of research objectives, recruitment, retention, and dissemination of results.

1.6	North Carolina State University researchers will work with public housing agencies and the Lumbee
Tribe to test a new pest control protocol for eradicating cockroach infestations and reducing cockroach
allergen levels in homes in both urban and rural communities in North Carolina. Community members
and pest management professionals will be included to help ensure the success of the study and the
future application of study findings. The study consists of three aims: Aim 1 will develop and validate a
new pest eradication protocol by assessing the efficacy and cost of several practices (gel bait
application, IGR sprays), then whole-home treatments, and finally resident participation. Aim 2 will
extend and generalize the most efficacious inner-city cockroach elimination protocol to rural homes in
eastern North Carolina and tribal homes (Lumbee Tribe). IEQ measures will include reductions in
cockroaches, allergens and endotoxin. Aim 3 will demonstrate a proof-of-concept transformative
community participatory intervention model with early intensive PMP inputs and sustainability through
community participation.

1.7 Virginia Polytechnic Institute and State University researchers will assess the efficacy and cost of
Assessment-based Pest Management (APM) protocols for controlling cockroaches and bed bugs in
public and other HUD-assisted housing. The researchers will study how the determination of pesticide
resistance among cockroach populations can be incorporated into pest management protocols and they
will test the efficacy of different heat systems for bed bug control. The study intends to determine the
costs of an APM baiting protocol for German cockroach control, the cockroach population resistance
profiles for resistance management recommendations, the efficacy of different whole heat-systems for
bed bug eradication and provide pest management training and contract writing seminars to managers,
facilities staff and public housing residents.

2. Lead Technical Studies Grant Awards

2.1	QuanTech was awarded funding for the development of a test kit for lead clearance testing. This
study builds on previously awarded HUD-sponsored work, Enhancing the Performance of Spot Test Kits
for Lead Based Paint Using Solid-Phase Dilution. The main objective of this study will be to develop a
fast, on-site procedure to determine clearance after lead hazard control work. The test kit will be based
on previous research developing a test kit to determine the presence or absence of lead-based paint. It
will potentially decrease the amount of time necessary to obtain clearance and reduce costs for
relocation. The test kit will be based on the previous work using the rhodizonate color change to pink in
the presence of lead.

Principal Investigator: Gary Dewalt, Ph.D., fgdewalt@comcast.net

2.2	Boston University researchers will study the effects of take-home contamination on children's blood
lead levels. This pilot study will characterize 60 homes of low-wage construction workers living with a
child. The study will evaluate interventions to reduce take-home contamination, and the effectiveness in
reducing metals in household dust and residents' blood. Intervention groups will be assigned to
different combinations of customized home assessment, take-home prevention training and
professional cleaning. Collaborators will include the Massachusetts Coalition for Occupational Safety and
Health, Brazilian American Center, Vietnamese Health Collaborative, New England Carpenters Training
Fund, and New England Region Laborers' Health & Safety Fund of North America.

Radon

National Radon Action Plan (NRAP)

IED continues to support the growing national network of federal agencies, private sector,
nongovernmental organizations (NGOs) and states to prevent lung cancer deaths through the
NRAP. Along with its founding members, the American Lung Association has brought in supporting
organizations (those who have signed a declaration of support) and emerging potential partners
(organizations identified to help drive progress) to increase the mitigation of existing homes and the
construction of new homes with radon-reducing features. The NRAP expands the efforts under the
Federal Radon Action Plan to focus on actions that go beyond federal governmental actions alone.

The NRAP presents a long-range strategy for eliminating avoidable radon-induced lung cancer in the
United States. The Plan's near-term goals are to reduce radon risk in 5 million homes and to save 3,200
lives by 2020. While the 2020 goals offer bold and important milestones, the NRAP's ultimate goal is to
eliminate avoidable radon-induced lung cancer in the United States by incorporating radon testing,
radon mitigation and radon-resistant construction into the systems that govern purchasing, financing,
constructing, and renovating homes and other buildings. Progress for NRAP strategies can be tracked at
www.radonleaders.org/resources/nationalradonactionplan.

Some highlights include—

•	NRAP Leadership Council held their face-to-face meeting on July 17 in Washington, D.C. Meeting
topics included strategy team updates, radon in workplaces, and tools/messaging on radon risks
in order to reach out to low income/EJ Communities.

•	Recent work with states, industry and NGOs to collaboratively push for more radon policies.

•	Tracking progress and reporting on NRAP strategies.

Credentialing of Radon Service Providers

As part of EPA's role to support state programs and to promote the availability of the best possible
radon services to consumers, EPA issued a Federal Register (FR) Notice seeking public feedback on a
proposed approach for developing voluntary criteria for organizations that credential radon service
providers. These criteria will establish an ongoing and open evaluation process for organizations wanting
to credential radon service providers. For more information about EPA's proposal, visit
www.epa.gov/radoii.

State Indoor Radon Grants (SIRG)

EPA awarded $8M to states and tribes in FY19 to support radon programs under the State Indoor Radon
Grants (SIRG) Program.

The SIRG Summary Report (for activities conducted during FY17 and FY18) was published in April 2019.

This report highlights the important work SIRG grantees are undertaking across the country to advance
risk reduction and aims to outline the overall progress to state and tribal programs and highlight
activities aligned with Congressional priorities and high-impact strategies. The report is available at

Building Codes

EPA continues to collaborate with industry and states to actively engage in efforts to promote adoption

of radon-resistant new construction (RRNC) practices by international, national, state and local building

codes. These efforts are mandated by the Indoor Radon Abatement Act and are also a key component of

the National Radon Action Plan.

• EPA held a Radon Codes Summit in May to bring together codes and radon experts to discuss
pathways forward and potential for RRNC adoption nationwide for schools.

• EPA hosted a webinar titled "Radon Protections in New Homes/' which addressed common
mistakes in design and installation of passive systems and new radon policy. (The webinar is
available on the Indoor AirPLUS website.)

• In collaboration with the American Association of Radon Scientists and Technologists (AARST),
EPA succeeded in maintaining the RRNC requirements and the radon testing for commercial
buildings in the International Green Construction Code (IgCC). The code published in 2018
requires radon new construction features be included, testing, and remediation of high levels.
The 2018 code also references and relies on AARST/ANSI standards.

• EPA developed several proposals for the ICC-700/ASHRAE-189.1 National Green Building
Standard, which have passed through committee votes positively and are now in public
comment. The proposals would require radon-reducing features and testing in green-rated
homes, including multifamily buildings and during renovations.

• EPA developed a proposal for the International Residential Code (IRC) that included a testing
component in the appendix, but it failed to pass the committee vote. EPA is now responding to
committee comments in the form of a public comment.

• EPA opposed a proposal to change appendix F of the IRC that would allow the option of
installing a side vent radon mitigation system. The proposal to allow a side vent radon mitigation
system, RB-286, passed the committee vote and will undergo a vote for final approval in
October 2019. EPA will attend the IRC hearing in October to continue to oppose this change.

Asthma

Technical Assistance Webinars

In July, EPA hosted two technical assistance learning opportunities:

• July 23 webinar, "Opportunities for In-Home Asthma Care in Native Communities: A Northwest
Initiative and Tribal Pilot Projectfeatured presentations on collaborative work in the Northwest to
ensure that Native children who need in-home environmental asthma care can receive it.

• July 30 webinar, "Collecting and Analyzing Data to Make Your Case," featured presentations on
criteria and processes designed to collect and analyze data effectively. Presentations focused on
how programs are using data to support and demonstrate real results in children with uncontrolled
asthma and the difference data makes in sustaining asthma intervention programs for long-term
success.

Both webinars, along with the questions and answers via the discussion forum, are archived on

Community of Practice

On September 25-26, in Washington, D.C., EPA in partnership with CDC and HUD convened the
Financing Environmental Interventions at the Asthma Community of Practice meeting. This event
brought together 65 leaders, representing federal agencies, regional, state, and community-based
asthma programs, to identify successful, systems-level approaches for financing environmental
interventions in homes to improve asthma outcomes. Community of Practice members include private
payers, state Medicaid programs, health care providers and community-level practitioners who are
leading innovative work to expand delivery of, and reimbursement for, in-home asthma care for the
families they serve.

2020 National Environmental Leadership Award in Asthma Management

Each year, EPA honors exceptional asthma programs through the National Environmental Leadership
Award in Asthma Management. For 2020, EPA has revised the application to align with a program shift
toward recognizing whole-community asthma care systems. When the revised application is launched in
November 2019, there will be an integration of the three categories (providers, plans and communities
in action) into one award application. The streamlined application maintains the three main topic areas:
Comprehensive Asthma Management (includes Management and Operations, Integrated Health Care
Services and Tailored Environmental Services); Getting Results; and Evaluation and Sustainability. This
remains the only national award for excellence in comprehensive asthma care, and the winners are
selected through a highly competitive process that includes an expert review panel with representatives
from EPA, CDC, HUD and other leaders in asthma care.

Please stay tuned for the announcement of the application launch in November 2019, and feel free to
forward it to your stakeholders as appropriate.

Comprehensive IAQ Interventions in Homes

Indoor air PLUS: New Homes

In April 2019, EPA's Indoor airPLUS (IAP) program hit another record for quarterly labeled homes, which
now total over 19,000 homes across the United States. EPA released Revision 4 of the Construction
Specifications in early 2018 and continues to share program updates in various industry forums around
the country.

On August 20th, EPA's IAP program announced winners for the 2019 Indoor airPLUS Leader Awards,
which largely focus on the efforts of partners to educate the public about IAQ through the use of Indoor
airPLUS sales tools and public marketing efforts. The awardees, including the distinguished Indoor
airPLUS Leaders of the Year, were recognized at the 2019 Energy & Environmental Building Alliance

Summit on October 2 in Denver, CO (summit.eeba.org). EPA's Indoor airPLUS also sponsored the Healthy
Homes track of the conference, which was attended by about 400 high-performance builders, raters,
manufacturers, and allied stakeholders.

The Indoor airPLUS program is working on updated program requirements to be included in the Indoor
airPLUS Version 2 (V2) Construction Specifications, anticipated to be released for public comment in
2020. Additionally, the program is working on the "re-release" of a partnership category for allied
organizations such as manufacturers, service providers, or other IAQ stakeholders interested in
supporting EPA's mission and developing IAP brand awareness. The revised "IAP Advocate Partnership"
is also slated for release in late 2019 or early 2020.

Indoor airPLUS: Existing Homes (IAP-X)

As part of IAP V2, the Indoor airPLUS program will include a labelling opportunity for existing homes. An
EPA existing homes indoor air quality (IAQ) label will also provide new opportunities for home
performance contractors and healthy home evaluators to partner with EPA to improve IAQ in the vast
segment of existing homes throughout the country. IAP-X is expected to be released for public comment
along with V2 of new homes.

Energy Savings Plus Health Guidance Updates

EPA is updating its guidance for single-family (2011) and multifamily (2016) housing to address IAQ
concerns and technology advancements during energy upgrades, through voluntary guidance that gives
best practices for improving IAQ in conjunction with energy upgrade work. These updates include
references to building codes, industry standards and URLs; best practices and technical guidance; recent
developments in pollutant control (e.g., particulate matter, radon, moisture); and general formatting for
improved usability by industry stakeholders. The end result will be guidance that will not only help users
improve their IAQ, but also will provide an opportunity to market improvements in existing homes.

The October 30, 2019, live webinar will feature a discussion with school district speakers who will reflect
and expand on the strategies outlined in the webinars rebroadcasted during October. Participants will
hear how these healthy green cleaning best practices are integrated into IAQ preventive maintenance
and learn how to utilize EPA guidance to yield a high return on investment, increase equipment
longevity, and reduce unexpected and often costly repairs. Participants will also have an opportunity to
have their questions answered by school district representatives who have successfully implemented
green cleaning and IAQ preventive maintenance strategies. Register for the October 30 webinar at

EPA is promoting a suite of resources titled Indoor Air Quality Tools for Schools: Preventive Maintenance
Guidance Documents to help school personnel take a holistic, proactive approach to IAQ issues. The
guidance leads school personnel through the steps to develop and implement an indoor air quality (IAQ)
preventive maintenance plan and offers a framework to make the case for an IAQ preventive
maintenance plan and gain buy-in from the school community. The resources are available online at
www.epa.gov/iaa-schools/indoor-air-qualitv-tools-schools-preventive-maintenance-guidance-
documents.

EPA staff will facilitate and present during sessions at the upcoming Virginia State Plant Managers
Association (VSPMA) and ISSA Green Clean Schools Track conferences on the Indoor Air Quality Tools for
Schools: Preventive Maintenance Guidance Documents. The sessions will address the dynamic
intersection of IAQ, preventive maintenance and energy efficiency. These sessions will provide
knowledge and tools to support maintaining and improving healthier, stronger and safer cleaning
programs that promote learning.

Improved Household Energy

ISO Standards

In the fall of 2018, the International Organization for Standardization (ISO) published the first
international standard for laboratory testing of cookstoves. The new standard includes protocols to test
and report the emissions, efficiency, safety and durability of cookstoves in a lab setting. The laboratory
test standard replaces an ISO International Workshop Agreement from 2012, which was led and
organized by EPA through the Partnership for Clean Indoor Air. It will serve as the basis for national
policies and programs on cookstoves, while also incentivizing manufacturers and developers to improve
stove quality and performance. An accompanying ISO technical report that benchmarks performance to
voluntary performance targets, or tiers, and provides guidance on how to understand and interpret
laboratory test results was also approved by member countries of the ISO Committee and published.
Development of the standard was led by EPA staff, with strong engagement of DOE staff. This summer
(2019) a second ISO household energy standard was finalized, "Guidance on Field Testing Methods for
Cookstoves." These voluntary documents provide a framework for organizations, countries and regions
to adapt and implement the protocols, metrics and targets based on their priorities over the coming
months and years. EPA is working with the World Health Organization, the Clean Cooking Alliance, and
ISO to organize and facilitate regional workshops to promote the adoption or the adaptation of the ISO
harmonized laboratory standards for clean cookstoves and clean cooking practices by countries. The
first workshop was held in Nepal for Asian countries in December 2018. The second workshop was held
in Uganda for English-speaking African countries in July 2019. At both workshops, the partners also
organized a concurrent workshop for staff of household energy laboratories to provide technical
assistance and guidance on laboratory testing methods contained in the new ISO standard. A third
regional workshop is scheduled to be held in West Africa in the spring of 2020 for Francophone African
countries, and later in 2020, a fourth workshop will be held in Latin America. ISO standards are reviewed
and updated regularly, so these standards can be updated based on future research and on the progress
in the cookstove and fuel market.

EPA staff are preparing to participate in the 9th Biennial Cookstove/Household Energy Forum, which will
be held in Nairobi, Kenya, on November 4-6, 2019. The Forum convenes more than 500 participants
representing 50+ countries. Attendees represent public and private sector health, energy and
environmental professionals, stove designers and manufacturers, researchers, NGOs and others who
share the common mission of reducing the health, environmental and economic burden from biomass
fuels and rudimentary stoves. Sessions focus on technical training, tailoring stove standards, health and
environmental research findings and creating collaboration opportunities. In conjunction with the
Forum, there will be an ISO Technical Committee 285 (TC285) Plenary Meeting (November 7-8).
