               City and County
                   of I)enver

            The  City and County  of
            Denver is leading by exam-
            ple in taking an aggressive
            approach to energy efficien-
            cy. Denver has upgraded a
            variety of facilities including
            Denver  General  Hospital,
city and county jails, libraries and the City
and County Building. The city has per-
formed upgrades as well at cultural attrac-
tions, such as  the  Zoo, Botanic Gardens
and the Museum of Natural History. By
the end  of 1994,  Denver  had upgraded
2.2 million square feet and  so far this year
has added another million to  that total
with an additional million expected by the
end of 1995.
   Much of Denver's success is due to the
Public Service Company  of Colorado's
Demand Side  Management  program,
which has provided thousands of dollars in
rebates. Denver is now saving more than
$52,000  annually on energy costs, with an
average  internal  rate  of  return  of  50
percent.  "Many of the conservation tech-
nologies we  implemented realize pay-
back—from energy savings alone—within
the first  budget year," said  Darryl Winer,
Denver's Implementation Director. "Then,
the  ongoing   energy  savings,  reduced
maintenance,  improved working condi-
tions, and  reduced pollution become no-
cost benefits!"
   While hosting a conference on April
29 for Green  Lights participants, Denver
demonstrated  to  other Partners in the
region what can be accomplished through
Green   Lights   and   ENERGY   STAR
Buildings. New  lighting  and building
technologies  were introduced,  and the
Public  Service Company outlined  its
rebate program. "Protecting the environ-
ment, improving the workplace, and sav-
ing taxpayer dollars, while  serving  our
constituency, is, simply good government,"
concluded Winer.

   When Paul Tseng, Chief, Engineering
and  Energy Services for Montgomery
County, Maryland, pitched Green Lights
to his County Executive two years ago, he
described the opportunity in a compelling
way. "I had calculated the energy savings
Green Lights  would produce  for  this
county, and told  the Executive that every
week we delayed joining Green Lights we
were  losing another  $13,000  of energy
savings. That statistic really helped get the
decision made," said Tseng.
   Since  Montgomery   County joined
Green  Lights  in June  of  1993,  the
County has moved ahead quickly to cap-

    ture those savings. Tseng and his staff put
    together a five-year plan for upgrading
    2,500,000  square feet of facility space.
    One principle guiding their upgrade pri-
    orities  was   maximizing  the  rebates
    received from their local utility, Green
    Lights  Utility Ally  Potomac Electric
    Power   Company   (PEPCo).   Since
    PEPCo is  phasing  out  a number of its
    rebate programs, Tseng  focussed first on
    rebatable  upgrades, such as LED  exit
    signs which  were installed  last  year in
    most of the county's buildings.
       Another strategy that has worked well
    for Montgomery County has been procur-
    ing lighting equipment through the State
    of Maryland's  existing  purchase agree-
    ments with lighting suppliers.  "Through
    the state contract, we can buy T8 lamps
    and electronic ballasts at discounts of up to
    83 percent,"  Tseng said. "I  recommend
    other Green Lights government Partners
    look into alternative purchase agreements
    already in place at sister agencies."
       The  results of Montgomery County's
    efforts speak for themselves. Annual sav-
    ings from reported upgrades top $270,000
    per year, on their way to over $700,000
    once  the  county  is  fully  upgraded.
    Average IRR is running a healthy 102
    percent, which translates into a one-year
    payback.

    building area. Lighting upgrades have  -5
    been completed in five buildings  and are  |
    in progress  at three others. MSD has also
    created a Green Lights capital fund to pay
for future upgrades. Green Lights provid-
ed MSD with a systematic  approach  to
examining one aspect of efficient facilities
and improvements in lighting are visible
and easy to explain to employees  and the
public.
   "The general public always  desires to see
efficient government facilities," said James
Hunt, MSD Physical Assets Director.
   Based on its Green  Lights  success,
MSD has decided to join  the  ENERGY
STAR Buildings program  and to  explore
the  Department  of  Energy's   Motor
Challenge. Through Green Lights, MSD
will utilize compact fluorescent task light-
ing in conjunction with  T8 fluorescent
ambient  lighting. The  ambient  lighting
will be controlled by occupancy sensors  to
reduce  lighting   consumption   during
evening  and weekend  hours when the
building is only partially occupied.

      County of San  Diego,
             California
   Though  relatively  new  to  Green
Lights,  the  County of San  Diego has
worked with its local utility to aggressive-
ly upgrade its facilities. Before installing
energy-efficient lighting, County officials
sat down with representatives from San
Diego Gas  & Electric  (SDG&E) to
devise an upgrade plan that would bene-
 San Diego County Administration Center
fit  both parties. Since  joining  Green
Lights, the  County  has upgraded 13
facilities covering over 1,549,000 square
feet, with SDG&E providing $515,000
in rebates. San  Diego is saving  almost
$375,000  annually as  a result  of its
efforts, and  it  is planning additional
upgrades in 1995.
   Partnering with the  local utility has
worked well for  San Diego.  Mindy Tao,
who works  in  the  Facilities  Services
Division of the  Department of General
Services, monitors the  progress  of the
upgrades.  "The  money  from  the local
utility  enabled us to  do the upgrades,"
said Tao.

    City of Phoenix, Arizona
   The City of Phoenix has maximized its
energy savings in its latest new construc-
tions. The new Central Library has been
designed with one of the most energy-
efficient interior  lighting systems  in the
country.  Through innovative  design—
stack-mounted lighting, five-foot T8 fluo-
rescent lamps and electronic ballasts, and
extensive day lighting—the building light-
ing load is only 1.14 watts per square foot.
This lighting design reduces the lighting
load  by 207 kWh annually, when com-
pared to other standard technologies, for
an energy reduction of 845,960 kWh per
             year. Green Lights Utility
             Ally  Arizona   Public
              Service, as part of its pro-
             gram to encourage ener-
             gy-efficient lighting, will
             award Phoenix $23,045 in
             recognition of the city's
             continuing dedication  to
             energy conservation in the

   How can a Partner upgrade its facilities
without  spending  any  capital?  Ask
Baltimore County, Maryland. Through an
agreement with Green Lights Utility Ally
Baltimore Gas  & Electric  Company
(BG&E), Baltimore  County  received
rebates  and  was  able  to finance  its
upgrades, repay BG&E with the savings,
and enjoy an immediate and  continuing
positive cash flow. Most of its projects paid
off in less than two years. "We are commit-
ted to  wisely spending taxpayer's dollars
and achieving savings where we can," said
Douglas Johnson,  Baltimore's Implemen-
tation Director. "Green Lights has given us
the opportunity to improve our employees'
lighting, improve  our  air  quality, and
increase County revenue to projects that
improve services to our residents."
   Baltimore has upgraded  over two mil-
lion  square  feet  including the County
Courts Building, Public  Safety Building,
County Office Building,  and Courthouse
and is saving more than $400,000 annually.

    Douglas County, Oregon

   Douglas  County, Oregon, the first
county Partner to join Green Lights, has
taken an aggressive attitude towards ener-
gy efficiency.
                     According    to
                   John Walker, Imple-
                   mentation Director
                   for  the  County,  al-
                   most 80 percent of
                   profitable lighting
                   upgrades have taken
                   place already,  with
                   the remaining square
                   footage surveyed and
scheduled for upgrades  later this  year.
Douglas County signed on as an ENERGY
STAR Showcase Buildings  Partner  last
year, and has since signed on the rest of its
buildings   into  the  ENERGY   STAR
Buildings program.
   EPA helped the  County highlight its
showcase facility, the Justice Building, in a
special recognition ceremony on June 26,
1995. Complete with new lighting, energy
management  system,  HVAC  system,
VSDs, and chillers, the Justice Building
has shown tremendous savings figures. "In
1990, our  monthly energy  bills  at the
Justice Building were as high as $24,000,"
noted Walker.  "After   the  showcase
upgrades, we've knocked around $16,000
off of that."  Walker's  enthusiasm  for
             ENERGY STAR Buildings and its goals is
             evident in his commitment to implemen-
             tation as well  as his eagerness to speak
             publicly about the merits of the program.
             Walker spoke about his County's experi-
             ence with ENERGY  STAR Buildings at
             EPA's Profitable Marketing Opportunities
             for Pollution Prevention Forum on April
             10,  1995  and he will be  addressing the
             American  Institute  of Plant  Engineers
             (AIPE) at its conference on October 26,
             1995 in Portland, Oregon.

                 City of Portland, Oregon

               The City  of Portland, Oregon became
             one of the first city Partners when it joined
             Green  Lights  in January 1992. Green
             Lights was a natural fit and became an
             important part of Portland's "City Energy
             Challenge"  program, a comprehensive
             program to increase energy efficiency in all
             sectors of the city by 10 percent by the year
             2000.
               The City has found some interesting
             and innovative solutions to common finan-
             cial hurdles. David Tooze, Energy Program

  Welcome New City and County Partners
    New government Partners are continuing to show their commitment to preserving
  the environment by joining Green Lights. These new Partners are realizing significant
  energy and cost savings by implementing upgrades. For example, the City ofTucson
  will be saving an estimated $230,000 annually, in addition to eliminating carbon diox-
  ide emissions of more than 1, 100 tons.
    These city and county Partners recently joined Green Lights and started better

          Preserving Our Planet s  Resources
                   Leon County Prevents Pollution
                     and Educates the Community
; eon County, Florida is a perfect exam-
-,,.ple of how government Partners can be
successful in Green Lights. Since joining
the  program in 1992, the County has
made great progress and shown its com-
mitment  to  preserving  our  planet's
resources by upgrading its lighting.
  To efficiently implement Green Lights,
Leon County formed an internal  imple-
mentation  team upon  joining the pro-
gram. This team helped Leon  County
upgrade 48 percent of its square footage,
including   the  County Courthouse in
Tallahassee, during its first two years in
the  program.  "The reason  we  joined
Green Lights is that we felt that the pro-
gram would provide our employees and
the people of Leon County with a higher
level of light while at the same time low-
ering the cooling load of the Courthouse,"
said Tom Brandy, Facilities Management
Director for the Leon County. "The pro-
gram has proved to provide a service to our
citizens while saving the taxpayer money."
The County is now saving over $90,000 in
annual  energy costs  and
reducing  electricity
by almost  680,000
kWh per year.
   To  publicize its
Green  Lights pro-
gress  and  educate
the  public about
energy efficiency,  Leon
County participated in Earth Day celebra-
tions. As part of this event, the County set
up  an  energy  meter  display  at  the
Courthouse demonstrating how much less
energy is consumed by  a energy-efficient
light bulb versus  a regular incandescent
light bulb, fi
                   Leon County Courthouse

Manager in the Portland Energy Office,
said, "Selling the concept of a coordinated
effort for energy savings was easy. The dif-
ficulty  came  in  convincing  the  City
Council to approve a new energy manager
position at a time when police and fire ser-
vices faced budget cuts."The city's solution
was to assess each of eight city bureaus one
percent of its annual energy bill, with a cap
of $15,000. This assessment was relatively
easy for the bureaus to absorb, and it gen-
erated an  annual program  budget  of
$70,000. No direct funding from the city's
general fund was required. In turn, a vari-
ety of services are provided  to  help the
individual bureaus reduce energy  bills,
including an annual energy use report and
energy audit assistance.
   The second significant hurdle the City
overcame was  identifying capital outside
of the city budget and gaining approval to
use it for energy efficiency  projects. The
solution was  a  Fiscal  Office  offer to
"piggy-back"  unfunded  energy projects
onto a scheduled debt sale. This $750,000
"loan," at 3.86 percent, is currently fund-
ing  46  projects which  will save over
$130,000 annually.
   Highly visible projects have offered a
prime opportunity to promote the success
of the city's energy savings  program. For
example, the Bureau  of General Services
completed a major lighting upgrade at one
of the city's  most visible facilities—the
Portland Building. This upgrade will save
the City about $40,000 per year and gen-
erate an IRR of over 25 percent and a sim-
ple payback of 3.8 years. ^'*

new type of lighting system which uses a
xenon metal halide lamp and a fiberoptic
distribution system,  also known as  the
light engine.
   Con Edison was the  first organization
in the world to use
this  type of light-
ing  system  in  a
commercial    real
estate application.
Although  the  sys-
tem  was  originally
designed  for other
uses, the  engineers
at  Con  Edison
were able to specify
a custom system for
the needs of the clock tower, and through
maintenance and energy savings were able
to recognize a three-year payback.
   The faces of the clock tower were orig-

Besides the headaches associated with the

 to change all the lamps on the face of the
 clock. In addition, the xenon metal halide
 lamp is located on the interior of building
 where it is easier to access.
   For  Con Edison,  a Green Lights
 Partner, the largest savings was in mainte-
 nance. However, the demand savings were
                      also  significant.
                      The  new system
                      is  brighter than
                      the old incandes-

                      than   80  per-

|f/                    22 kW  to  less
                      than  4 kW.
                         Through  its
 clock tower, Con Edison has found a
 unique  use  for  the xenon metal halide
 lamp and fiberoptic system. Other uses for
 this new lighting system are egress, deco-
 rative, underwater, neon replacement, and
 sign lighting. Another excellent applica-
 tion of this type of system is in hazardous
 locations where the light sources need to
 be  remotely  located,  such as  laboratory
 areas where explosive gases are present in
 the air.
   The xenon metal  halide lamp is an
 energy-efficient  alternative to incandes-
 cent and halogen lamps for use in fiberop-
 tic systems. This is a great example of how

             TIP   OF   THE   MONTH
 Selecting and  Applying Occupancy Sensors
      Occupancy sensors can significantly reduce energy costs.
              Follow these tips for proper installation.
L'roperly  applied,  occupancy  sensors
>  offer the potential  to  reduce  energy
costs by as much as 75 percent. The key to
achieving these savings is proper applica-
tion. For reliable operation and maximum
profits from your occupancy sensor instal-
lation, consider the following application
tips:

Work with experienced occupancy
sensor professionals.  Successful occu-
pancy sensor applications require a com-
plete understanding of the technology's
operation, performance limits, and com-
patibility issues. Occupancy sensor ven-
dors are willing to help  participants apply
the tips that follow for selecting and
using appropriate technologies for  specif-
ic applications. And vendors can assist in
arranging trial installations for demon-
strating performance  and gaining user
acceptance. By working with a profes-
sional, occupancy sensors can easily lead
to big savings.

Select products that provide ade-
quate coverage.  Specifiers should pay
particular attention to the published size
and shape of the coverage area that
defines the physical limits of the sensor's
ability to detect motion. Note  that this
coverage area may be reduced  based on
reduced physical activity, lower ceiling
heights, the use of partitions, or reduced
sensitivity settings. In some cases, more
than one occupancy sensor may be
required in a space to provide  adequate
motion-sensing coverage, as in the case of
a large, open office area.
Select mounting locations and
technologies based on room
geometry and activities.
Infrared (IR) Sensors
'  IR sensors require line-of-sight
   between the  sensor and the motion.
   Wallbox-mounted IR sensors may not
   work well where partitions, walls, or
   furniture may block direct viewing of
   occupant movement.
•  IR sensors are most sensitive to motion
   lateral to the sensor.
•  The magnitude of required occupant
   motion is directly proportional to the
   distance from the occupant to the sensor.
•  IR sensors do not require an enclosed
   space; they work well outdoors and in
   high-ceiling  areas.

Ultrasonic (US)  Sensors
•  US sensors do not require line-of-
   sight to sense motion in spaces that
   are enclosed  with hard surfaces (such
   as in rest rooms). However, US sensors
   may require line-of-sight to sense
   motion in large, open office areas with
   fabric-covered partitions.
•  US sensors are most sensitive to motion
   toward and away from the sensor.
•  The magnitude of required occupant
   motion increases with distance from
   the sensor.
•  US sensors require an enclosed space;
   they should not be used outdoors or in
   high-bay areas.

Design sensor installations to avoid
false signals.
   Infrared Sensors:  IR  sensors may  be

located in positions that allow the sensor
to have line-of-sight into an adjacent cor-
ridor, which could  result in keeping the
lights on unnecessarily.  By applying  a
masking  material to the appropriate por-
tion of the IR sensor's lens, this potential
problem can be avoided.
   Ultrasonic Sensors: US sensors can be
activated by vibrations (which,  for exam-
ple, may be caused by the starting of an air
conditioner). Also, some ultrasonic sensors
can be activated by moving air and should
not be used in areas where strong air cur-
rents exist.

After installation, tune the sensor
based on the  type of motion expected
in the space.  The sensor's sensitivity set-
ting should be  adjusted based on the
activities that are expected to occur in the
space. A proper sensitivity setting will
ensure that normal occupant motion is
detected without triggering responses to
extraneous signals.
   A proper time delay setting will prevent
the lights from switching off during inter-
vals when people are actually in the room,
but move too little or too slowly to be
detected by the sensor.

ing, attend a Lighting Upgrade Workshop

   To help Green Lights participants follow
EPA's ENERGY STAR Buildings initiative, the
Update is documenting the  results of the
Showcase Building.',  participants  as  they
implement each stage of the program.  This
article, the fifth in a series, describes Stage 4:
Improved Fans and Air-Handling Systems.
£™;
Han  motors  in air handlers can  account
I for as much as 20 percent of the energy
usage in commercial buildings. There are
several opportunities that can significantly
reduce energy consumption by increasing
fan system efficiency. Improving &fl sys-
tems  and air  distribution is often one of
the most profitable investments a building
owner can make when upgrading the per-
formance of a building.
   In this fourth  stage of the  ENERGY
STAR Buildings process, the  payoffs of
implementing Stages 1, 2, and 3  are em-
dent. Building tuneups (Stage 2) assure
that equipment upgrades in Stages-4 and 5
are applied to properly functioning equip-
ment. Also,  by  implementing Green
Lights (Stage 1),  tuning up the building
systems (Stage 2),  and reducing additional
building H¥AC loads (Stager 3}?, building,,
owners  can significantly reduce the size
and  cost  of  mechanical  equipment
upgrades in Stages 4 and 5.  -
   After Stages 1, 2, and 3, rtany, of the
fans will be larger than necessary'to handle
the reduced loads. Excessively "oversized"
fan systems not only waste energy, but also
increase noise levels,  and cause greater
wear  on equipment. Oversized '-fins  are
ideal  candidates for variable; speed, drives
and motor downsizing.This if a.powerfijtl
example of the ENERGY STAR Buildings
approach,  which is to  maximize energy
savings and lower the  costs to perform
upgrades. Four actions should be consid-
ered to save energy and correct fan  over-
sizing:
   1. Larger fan pulleys: An existing fan
pulley often can be replaced with a larger
fan pulley, which will reduce air flow by
reducing the fan speed. Reducing a fan's
Speed by 20 percent reduces its energy
requirements by about 50 percent.
   2. Energy-efficient motors: Compared
to  standard  motors,  energy-efficient
motors use  3-8  percent less energy, are
more reliable, and generally have longer
warranties. Replacing existing motors with
new energy-efficient motors can reduce
maintenance costs  and can postpone or
eliminate the need to  expand  electrical
supply systems.
   3. Variable speed drives: Variable speed
drives (VSDs) save energy by electronical-
ly controlling the speed and torque of the
motor to satisfy changing system loads.
The only  power
consumed  is  the
power required to
meet  the  load.
Under  part-load
conditions, a VSD
will reduce air flow
by  reducing  fan
Speed, which is far
more efficient than
running the fan at
foil   speed  and
reducing  air flow
by partially closing
a damper. VSDs save  energy since the
power  consumed is proportional to the
cube of the air flow. For example, if the air
flow is reduced by half (a factor of two),
the fan power consumption is reduced by
approximately a factor of eight.
   ENERGY STAR Showcase Building par-
ticipant Mobil  Corporation  installed 21
variable speed drives in its  research and
development facility in Dallas, TX. These
upgrades  were  very  profitable, saving
approximately $105,000 annually, with an
internal rate of return (IRR) of better than
40 percent. This IRR translates into a sim-
ple payback of  slightly more  than two
years. The table below shows the results of
selected   ENERGY   STAR    Showcase
Buildings participants.
   4. Duct static pressure: The duct  static
pressure of a fan system is based on 100
percent design air flow. After load reduc-
tions in Stages 1 through 3, the fan system
may never reach 100 percent design air
flow, and the design static pressure can be

           Lighting management company helps Partners
                 finance and complete their upgrades
 IllumElex, a company that helped estab-
 Slish   the   Lighting   Management
 Company arm of the Green Lights Ally
 program, is an ardent supporter of energy
 efficiency. In 1995, while IllumElex Green
 Lights Surveyor Allies  were helping the
 company meet its Green Lights lighting
 upgrade goals,  the company formed  its
 IllumElex Financial Services Corporation
 to help  its customers finance lighting
 upgrade projects.
   The  group  developed Energy Solu-
 tion!, a program that provides a full range
 of funding alternatives for customers "who
 can't divert capital into lighting improve-
 ments,"  said  IllumElex's  Green Lights
 Coordinator Steve Strom.  The program
 "allows the customer to use the savings on
 its monthly electric bill resulting from the
 lighting improvements to pay for the pro-
ject's materials and labor. Therefore, there
 is  no capital  outlay," explained  Strom.
 IllumElex's first Energy Solution!  cus-
 tomer saw a $200 per  month positive cash
 flow because its utility cost savings exceed-
 ed its monthly payments for the lighting
 upgrade.
   As for IllumElex's own upgrades, five
 more facilities  throughout  the country
 have been completed to bring the compa-
 ny's upgrade to 100 percent. These  pro-
                                       jects are saving the company nearly $4,000
                                       in energy costs annually. F-40 lamps have
                                       been replaced by energy-saving T8s with
                                       electronic ballasts, incandescent lamps and
                                       exit  signs have been replaced with com-
                                       pact fluorescent lamps, and high-intensity
                                       discharge systems have been installed to
                                       improve the work environment.
                                          IllumElex looks for additional money-

                                       their Green Lights commitment.
                                          Recently, IllumElex formed a winning
                                       partnership  with Duracell USA.  The

sought  assistance  with  upgrading its
106,000 square-foot office, laboratory and
manufacturing facility. Duracell USA con-
sidered  involvement in  Green  Lights
when it chose a lighting management firm
to help  with the upgrades, according to
Duracell USA Green Lights Implementa-
tion Director Irwin Tronchin.
   Duracell's  Facilities   Engineering
Manager, Ed Bullington, got the corpo-
rate ball rolling by arranging a survey of
the  20,000  square  foot   facility  in
Lexington, NC. IllumElex stepped in to
do the  job—testing different  lighting
technologies  for employee acceptance.
   IllumElex also  arranged a continuing
maintenance program to ensure the new
equipment   is working  properly  and
Duracell has replacement lamps  in stock
and the Ally helped Duracell complete
their implementation report forms.
   IllumElex's familiarity with  energy-
efficient lighting  practices  and  Green
Lights progress reporting methods made
Duracell's transition to  energy-saving
lighting  a smooth one. "Green  Lights
involvement  has provided Duracell an

ment to  helping the environment  and our
desire to make energy-conscious choices,"
said Tronchin. Pi

from Americorps-funded City Year, an
innovative  national  community  service
program based in Boston. The City Year
EPA/Environmental Industries team was
led by Norman Willard of EPA's New
England office, and Sarah Hammond-
Creighton of Tufts University about the
principles of electricity generation, ener-
gy efficiency, lighting, and pollution pre-
vention.
   The City Year team performed light-

McBreen and Green Lights Utility Ally
Boston Edison at the offices of NuEstra
Comunidad Development Corporation,
the  Dudley  Street  Neighborhood
Initiative (DSNI), and at City Year's
Roxbury office. NuEstra  and  DSNI
became the first non-profit community
development corporations to join  Green
Lights. These offices now can  serve as
demonstration sites to  show inner city
businesses and residents the energy and
money-saving benefits of efficient light-
