REPORT DISCLAIMERS
This audit was performed using American Recovery and Reinvestment Act (ARRA)
funds, managed by the Alaska Housing Finance Corporation (AHFC).
This energy audit is intended to identify and recommend potential areas of energy
savings, estimate the value of the savings and approximate the costs to implement the
recommendations. Any modifications or changes made to a building to realize the
savings must be designed and implemented by licensed, experienced professionals in
their fields. Lighting recommendations should all be first analyzed through a thorough
lighting analysis to assure that the recommended lighting upgrades will comply with
State of Alaska Statute as well as Illuminating Engineering Society (IES)
recommendations. Energy Audits of Alaska, LLC and Central Alaska Engineering
Company bear no responsibility for work performed as a result of this report.
Payback periods may vary from those forecasted due to the uncertainty of the final
installed design, configuration, equipment selected, and installation costs of
recommended Energy Efficiency Measures (EEMs), or the operating schedules and
maintenance provided by the owner. Furthermore, EEMs are typically interactive, so
implementation of one EEM may impact the cost savings from another EEM. Neither
the auditor, Central Alaska Engineering Company, AHFC, or any other party involved in
preparation of this report accepts liability for financial loss due to EEMs that fail to meet
the forecasted payback periods.
This audit meets the criteria of an Investment Grade Audit (IGA) per the Association of
Energy Engineers definition, and is valid for one year. The life of the IGA may be
extended on a case-by-case basis, at the discretion of the AHFC.
IGA’s are the property of the State, and may be incorporated into AkWarm-C, the
Alaska Energy Data Inventory (ARIS), or other state and/or public information system.
AkWarm-C is a building energy modeling software developed under contract by AHFC.
This material is based upon work supported by the Department of Energy under Award
Number DE-EE0000095. This report was prepared as an account of work sponsored
by an agency of the United States Government. Neither the United States Government
nor any agency thereof, nor any of their employees, makes any warranty, express or

Guidance to the reader:
The Executive Summary is designed to contain all the information the building
owner/operator should need to determine how the subject building’s energy
efficiency compares with other similar use buildings, which energy
improvements should be implemented, approximately how much they will cost
and their estimated annual savings. Sections 2 through 7 of this report and the
Appendices, are back-up and provide much more detailed information should
the owner/operator, or their staff, desire to investigate further.
This audit was performed using American Recovery and Reinvestment act
(ARRA) funds to promote the use of innovation and technology to solve energy
and environmental problems in a way that improves the State’s economy. The
audit and this report are pre-requisites to access AHFC’s Retrofit Energy
Assessment Loans (REAL) program, which is available to the building’s owner.
The purpose of the energy audit is to identify cost-effective system and facility
modifications, adjustments, alterations, additions and retrofits. Systems
investigated during the audit included heating, ventilation, and air conditioning
(HVAC), interior and exterior lighting, motors, building envelope, and energy
management control systems (EMCS).

The site visit to the subject building occurred on December 9th, 2011. Due to the
nature of this building’s use (i.e. Police Department Headquarters), the auditors
did not have access to all rooms. As a consequence, some assumptions have
been made in this report, including details of the Heating, ventilation and air
conditioning (HVAC) system and its controls.
This building houses offices, a crime lab, the dispatch center, evidence storage,
fitness and locker facilities. The building was constructed in 1984 and numerous
improvements and/or renovations have occurred since then. Noteworthy
renovations include the crime lab expansion in 1996, a fitness and locker
remodel, parking extension and canopy and fuel island in 1998 and the
computer server room HVAC in 2006.
The interior and exterior of this building are in good condition and well
maintained.
Energy Consumption and Benchmark Data
This building uses natural gas provided by Enstar Natural Gas Co., and
electricity provided by Chugach Electric Association (CEA). Benchmark utility
data and billing history for 2009 and 2010 obtained by the auditor, is
summarized in Tables 1 and 2 below and presented in detail, by month, in
Appendix F.
Table 1
2009 2010
Consumption Cost Consumption Cost
Electricity ‐ kWh 2,001,440 $ 228,797 2,052,000 $ 198,053
Natural Gas ‐ CCF 43,652 $ 44,540 40,679 $ 35,599
Totals $ 273,337 $ 233,652
A benchmark measure of energy use relative to other similar function buildings
in the area is the Energy Use Index (EUI), which takes the total annual energy
used by the facility divided by the square footage area of the building, for a value
expressed in terms of kBTU/SF. This number can then be compared to other
buildings to see if it is average, higher or lower than similar buildings in the area.
Likewise, the Energy Cost Index (ECI) is the cost of all energy used by the
building expressed in $/SF of building area. The comparative values for the
subject building are shown in Table 2 below.

As observed in Table 2 above, the energy consumption of this building, when
compared with similar use buildings in Anchorage, is high. This required further
investigation. A deeper analysis shows that this building has excessive
consumption of electricity and somewhat less gas consumption, when compared
with the other two buildings. See Chart 1 below.
The auditor attributes the lower gas consumption to the quality of the subject
building’s shell (the auditor has visited the Woodland park school, it is an old
building in need of an upgrade) and the well functioning HVAC system. The
extremely high electrical consumption is believed to be a result of the
significantly higher occupancy levels and 24/7/365 nature of this building’s
usage, coupled with the very high use of electronics. There are over 300 PC’s
and 6 racks of computer server gear in use in this building; this accounts for
35% of the total electrical consumption of the building.
Various Energy Efficiency Measures (EEMs) have been analyzed for this
building to determine if they would provide energy savings with reasonably good
payback periods. EEMs are recommended for reasons including:
1.) they have a reasonably good payback period
2.) for code compliance

3.) end of life (EOL) replacement
4.) reasons pertaining to efficient building management
strategy, operations, maintenance and/or safety
All the EEMs considered for this facility are detailed in the attached AkWarm-C
Energy Audit Report in Appendix B and in Appendix D. Each EEM includes
payback times, estimated installation costs and estimated energy savings.
The summary EEM’s that follow are a distillation of all of the EEM’s
recommended, considering three perspectives: overall efficiency of building
management, reduction in energy consumption and return on investment (ROI).
Efficient building management dictates, as an example: that all lights be
upgraded, that lamp inventory variations be minimized and that all appropriate
rooms have similar occupancy controls and setback thermometers - despite the
fact that a single or several rooms may have an unjustifiably long payback on
their individual lighting or controls upgrade.
Some of the summary EEM’s below contain individual EEM’s that are grouped
by type (i.e. all relevant lighting upgrades are summed and listed as a single
upgrade, all thermostat setback retrofits are grouped together and listed as a
single upgrade, etc.) and are prioritized with the highest ROI (shortest payback)
listed first. Table 3 at the end of this section summarizes these EEM’s.
A.) ROOM TEMPERATURE SETBACK THERMOSTATS
It is assumed that the HVAC control system is not currently
programmed up to manage night time setback temperatures based
on zones that are occupied. Approximately 17% of this building is
used continuously, the other 83% could have night time setback
temperatures programmed – depending on how the HVAC zones
are set up. It is recommended to enable night time setback
temperatures in all of the zones that are used only one shift per
day, reducing room temperatures to 55F during unoccupied
periods. It is further assumed that he HVAC control system has
the capability to allow this. This EEM is detailed in Appendix B-1.
Combined Setback Thermostat EEM’s:
Estimated cost $ 1,500
Annual Savings $ 7,114
Payback 3 months
B.) MOTORS
Generally, paybacks justify that all motors 5HP or larger, operating
for 1500 hours per year, or more, at continuous speed, should be
ENERGY AUDITS OF ALASKA ANCHORAGE POLICE DEPARTMENT HEADQUARTERS
June 28, 2012 Page 9 of 55
replaced at EOL with premium efficiency motors. Paybacks will
justify that motors 5HP or larger operating for 5000 hours per year
or longer, be replaced with premium efficiency motors immediately.
See table 4 in Appendix D-2 for complete, large-motor listing and
recommended premium upgrades. In this building, none of the
AHU motor nameplates were accessible, so efficiency ratings
could not be obtained. Consequently, only two motors are
recommended for replacement, at burnout, with high efficiency
versions.
Motors recommended to be replaced at EOL:
Estimated cost $ 400
Annual Savings $ 386
Payback 1.1 years
C.) BEVERAGE VENDING MACHINES
Vending machines typically run regardless of usage and
occupancy. There is a device which, when retro-fitted to an
existing vending machine, cycles the compressor and machine
lights based on usage patterns and proximity sensors. This
“Vending Miser” typically saves 46% in energy consumption while
still maintaining cold beverages. See Appendix B-7 and
www.vendingmiser.com.
Vending Machine EEM:
Estimated cost (for 2 machines) $750
Annual Savings $647
Payback 1.2 years
D.) PERSONAL COMPUTERS
There are approximately 304 PC’s with monitors in this building,
and an additional 142 more monitors. Due to the nature of the
work they are doing, many of these PC’s are high grade, high
powered computers. No recommendation is made to change
these computers. However, there are approximately 162 “normal-
use” PC’s in the building used by office and clerical staff, and it is
recommended to replace these PC’s with laptops at their EOL A
laptop will use approximately 50% of the energy a desktop PC
uses and the incremental cost is $200 each. See Appendix B-13.
PC replacement at EOL, EEM:
Estimated cost $ 32,400
Annual Savings $ 8,615
Payback 3.7 years
ENERGY AUDITS OF ALASKA ANCHORAGE POLICE DEPARTMENT HEADQUARTERS
June 28, 2012 Page 10 of 55
E.) HEADBOLT HEATER CONTROLS
There are retrofit headbolt heater receptacles that replace
standard duplex receptacles. They contain an integrated
microprocessor and thermometer that cycles power on and off in
response to the outside air temperature. Energy savings is
typically 50%. The 17 headbolt heaters east of the subject
buildings utilize duplex receptacles, and are therefore retrofit-able.
It is assumed that they are used for 2 hours, 3 times per day,
during shift changes. See Appendix B-12.
Headbolt Heater Control EEM:
Estimated cost $ 4,250
Annual Savings $ 767
Payback 5.5 years
F.) LIGHTING AND LIGHTING CONTROLS
This lighting fixtures inside this building are very inconsistent,
indicating that a building-wide upgrade has never been
undertaken. It is recommended to upgrade all T12-40 watt lamps
to T8-28 watt, energy saver lamps and where fixtures have
magnetic ballasts, replace them with high efficiency electronic
ballasts. Occupancy sensors should be added wherever possible.
It is also recommended that at the next building re-lamp, change
all the T8-32 watt lamps to T8-28 watt energy saver lamps, which
will result in a 12% energy savings with a $3 incremental additional
lamp cost (see Appendix E).
Upgrading the exterior lighting from high pressure sodium (HPS) to
LED lighting is also recommended.
The completion of a full lighting upgrade for this building is
summarized below, and detailed in Appendix B items 2-6, 8-11,
14-30. For additional information on occupancy sensors and
lighting systems, see Appendix.
Despite the relatively long payback on a complete lighting upgrade
(9.1 years) it is still highly recommended from both building
management and future energy savings perspectives.
Combined Lighting Control EEM’s:
Estimated cost $ 285,062
Annual Savings $ 29,137
Payback 9.1 years
ENERGY AUDITS OF ALASKA ANCHORAGE POLICE DEPARTMENT HEADQUARTERS
June 28, 2012 Page 11 of 55
G.) PLUMBING FIXTURES
It is recommended that all urinals should be retrofitted or be
replaced with ultra low flow models. Urinals and faucets should
have proximity sensing on/off controls. Manually flushed toilets
should be retrofitted with dual flush valves. This audit does not
include water usage and AkWarm-C does not allow for the
modeling of this, see Appendix D-1 for additional detail.
Table 3 summarizes the estimated cost totals and estimated annual
savings totals of the nine (A. through I.) summary EEM’s listed above.
Table 3
Combined total of priority, high‐ROI,
strategically recommended EEM’s listed above:
Estimated total cost $ 324,326
Annual Savings $ 46,667
Simple payback 6.95 years
Does not include design or construction management costs
In addition to EEMs, various Energy Conservation Measures (ECMs) are
recommended since they are policies or procedures that are followed by
management and employees that require no capital outlay. Examples of
recommended ECMs for this facility include:
1. Turning lights off when leaving a room that is not controlled by an
occupancy sensor.
2. All man-doors, roll-up doors and windows should be properly
maintained and adjusted to close and function properly.
3. Turn off computers, printers, faxes, etc. when leaving the office.
The total of all 32 recommendations listed in Appendix’s B and D of this report,
estimate to save $46,667/year, with an installed cost of $324,326. The
combined payback on this investment is 6.95 years. This does not include
design or construction management services, Some of the costs totaling
$324,326 are incremental costs for higher efficiency replacements, so actual
budgetary costs for unit replacements will be higher. See individual EEM’s for
further detail.

2. Audit and Analysis Background
Program Description: This audit included services to identify, develop, and
evaluate energy efficiency measures for the subject building. The scope of this
project included evaluating the building shell, lighting, hot water generation and
HVAC equipment. The auditor may or may not identify system deficiencies if
they exist. The auditor’s role is to identify areas of potential savings, many of
which may require more detailed investigation and analysis by other qualified
professionals.
a. Audit Description and Methodology: Preliminary audit information was
gathered in preparation for the site survey, including benchmark utility
consumption data, floor and lighting plans, and equipment schedules where
available. A site visit is then performed to inventory and evaluate the actual
building condition, including:
i. Building envelope (walls, doors, windows, etc)
ii. Heating, ventilating, and air conditioning
iii. Lighting systems and controls
iv. Building specific equipment
v. Plumbing Systems
b. Benchmark Utility Data Validation: Benchmark utility data provided
through AHFC’s initial phase of their REAL program is validated, confirming
that meter numbers on the subject building match the meters from which the
energy consumption and cost data were collected. If the data is inaccurate
or missing, new benchmark data is obtained. In the event that there are
inconsistencies or gaps in the data, the existing data is evaluated and
missing data points are interpolated.
c. Method of Analysis: The information gathered prior to the site visit and
during the site visit is entered into AkWarm-C, an energy modeling software
program developed specifically for AHFC to identify forecasted energy
consumption. The forecasts can then be compared to actual energy
consumption. AkWarm-C also has some pre-programmed EEM retrofit
options that can be analyzed with projected energy savings based on
occupancy schedules, utility rates, building construction type, building
function, existing conditions, and climatic data uploaded to the program
based on the zip code of the building. When new equipment is proposed,
energy consumption is calculated based on manufacturer’s cataloged
information.
Energy cost savings are calculated based on the historical energy costs for
the building. Installation costs include the labor and equipment required to
implement an EEM retrofit, but design and construction management costs
are excluded. Cost estimates are +/- 30% for this level of audit, and are
derived from one or more of the following: Means Cost Data, industry
publications, experience of the auditor, local contractors and/or equipment
suppliers. Mechanical Solutions, Inc, Yaskawa America Drives, and J.P.
ENERGY AUDITS OF ALASKA ANCHORAGE POLICE DEPARTMENT HEADQUARTERS
June 28, 2012 Page 13 of 55
Sheldon, all in Anchorage, were consulted for some of the VFD controls,
dehumidification, boiler, air handling retrofit and/or replacement costs.
Maintenance savings are calculated, where applicable, and are added to the
energy savings for each EEM.
The costs and savings are considered and a simple payback period and ROI
is calculated. The simple payback period is based on the number of years
that it takes for the savings to pay back the net installation cost (Net
Installation costs divided by Net Savings.) In cases where the EEM
recommends replacement at EOL, the incremental cost difference between
the standard equipment in place, and the higher efficiency equipment being
recommended is used as the cost basis for payback calculation. The SIR
found in the AkWarm-C report is the Savings to Investment Ratio, defined as
the breakeven cost divided by the initial installed cost.
A simple life-time calculation is included in the AkWarm-C calculation for
each EEM. The life-time for each EEM is estimated based on the typical life
of the equipment being replaced or altered. The energy savings is
extrapolated throughout the life-time of the EEM. The total energy savings is
calculated as the total life-time multiplied by the yearly savings.
d. Limitations of the Study: All results are dependent on the quality of input
data provided, and may only act as an approximation. In some instances,
several methods may achieve the identified savings. This report is not a
design document. A design professional, licensed to practice in Alaska and
in the appropriate discipline, who is following the recommendations, shall
accept full responsibility and liability for the results. Budgetary estimates for
engineering and design of these projects in not included in the cost estimate
for each EEM recommendation, but these costs can be approximated at 15%
of the cost of the work.

4. Building Description and Function:
The site visit and survey of subject building occurred on December 9th, 2011.
The ambient outside temperature was 27F.
The building houses the headquarters for the Anchorage Police Department. It
has two stories consisting primarily of offices, but also includes a crime
laboratory, fitness center, locker rooms and showers, and an evidence storage
facility. The first floor has 44,892 square feet, the second floor has 18,158
square feet, for a building total of 63,050 square feet.
The building is constructed on a reinforced concrete slab poured on grade, 4”
and 6” thick. The building’s walls are 4” and 6” concrete masonry units (CMU’s)
finished in the inside with 2”x6” metal studs filled with R-19 batt, covered by
gypsum for a composite insulation value of R-10. The second floor and roof are
concrete slabs poured over metal decking supported by steel trusses and
purloins. The roof consists of 6” of rigid insulation and a membrane on the flat
sections and standing seam metal roofing on the second floor sloped sections.
The roof composite insulation value is R-32.
The windows in this building are in good condition, have aluminum frames and
double pane glass.
Building details are as follows:
a. HVAC
Heating & Cooling System: Space heating in this building is
provided by two 28-year old, Cleaver Brooks, 3347 MBH,
80% efficient scotch marine, dual fuel boilers. They are
currently fired by natural gas and do not appear to have used
fuel oil in a long time. Heat distribution is through finned tube
baseboard heaters around the building’s perimeter, 15 unit
heaters running “wild” (i.e. no local fluid valve control) and a
series of air handlers (AHU’s) equipped with heating coils.
The room ventilation boxes appear to be constant volume,
but most of the AHU’s are equipped with variable frequency
drives (VFD’s) to provide variable air flow. Room and zone
temperature input is through rooms sensors, and is not user-
adjustable. Building cooling is supplied by 4 rooftop
drycoolers, a large 125 ton air conditioning unit and a smaller
13 ton unit, all rooftop. Individual air conditioning units are
utilized for server room and battery room cooling.
The heating and ventilation control systems utilize pneumatic
sensing and actuation, including VFD input, and judging from
the natural gas consumption, the controls are operating
properly. The air conditioning is controlled by a dedicated
Leibert DDC unit.
ENERGY AUDITS OF ALASKA ANCHORAGE POLICE DEPARTMENT HEADQUARTERS
June 28, 2012 Page 16 of 55
Ventilation: Ventilation, exhaust and make up air is provided
by 26 air handlers (AHU’s) distributing or exhausting through
constant volume room boxes. 12 of the AHU’s are equilpped
with VFD’s utilizing pneumatic PID control to provide variable
air flow.
b. Appliances: There are 6 full size and 23 half-size
refrigerators in this facility. All but 1 of the full sized
refrigerators appear to be less than 5 years old, and are
therefore presumably, Energy Star rated. There are two
residential type dishwashers, neither appears to be well used.
21 microwaves, 17 personal coffee makers and 51 personal
printers round out the appliance inventory in this building.
The crime lab is well equipped with fume hoods, photo light
tables, and other analysis equipment – see Appendix C for a
complete equipment schedule. There are 304 PC’s with
monitors and 142 additional computer monitors in use in this
building, as well as a significant amount of other electronics –
so much so, that the PC’s and electronics by themselves,
account for approximately 35% of the total electrical usage of
the building. “VendingMiser’s” are recommended for the 3
beverage vending machines. See Appendix A for photos and
B-7 for retrofit details.
c. Plumbing Fixtures: This building contains a total of (21)
toilets, (7) urinals, (21) lavatory sinks and (8) showers. All
fixtures except 3 urinals (which utilize proximity sending
valves) are manually operated and appear to be post-1992,
so consume 1.,6 gpf (toilets) and 1 gpf (urinals) and 2.6 gpm
(shower heads). See Appendix D-1 for EEM
recommendations.
d. Domestic Hot Water: Domestic hot water (DHW) in this
building is provided by 3 Amtrol, 80 gallon, indirect hot water
generators located in the boiler room. There is an additional
50 gallon electric hot water heater in a storage closet; it is
presumed to supply either the crime lab or the lunch/break
room dishwasher.
e. Interior Lighting & Controls: As previously mentioned, the
lighting in this building has not been consistently upgraded.
There is a mix of T12 fixtures with magnetic ballasts, T8
fixtures with electronic and magnetic ballasts, and nearly 100
incandescent bulbs still in use. Lighting levels in the building,
for the most part, are good. Random measurements taken in
rooms with a single switch ranged around 65 foot candles (50
ENERGY AUDITS OF ALASKA ANCHORAGE POLICE DEPARTMENT HEADQUARTERS
June 28, 2012 Page 17 of 55
foot candles is recommended in offices). Light levels in
rooms with 1/3-2/3 lighting (one switch actives 1 lamp in each
fixture, the second switch activates the other 2 lamps in each
fixture) measured 24, 41 and 65 foot candles, respectively. It
is recommended to change all T8-32 watt lamps to T8-28
watt energy saver lamps. This results in a 3% lighting
reduction, but based on the above mentioned measurements,
there is still adequate lighting and there is a 12% energy
savings.
Lighting Controls: There are no occupancy sensors in the
building. All room and office lights are manually activated by
a normal wall switch or a “T-key” wall switch in a few
instances. Appendix B details completion of a full lighting
upgrade including occupancy sensors. See Appendix E for
additional information on the different types and uses of
occupancy sensors.
Exit signs for the most part are self illuminating, non-electric
or LED.
f. Exterior Lighting: Exterior lights include wall packs on the
building, soffit lights around the perimeter, walkway lights in
the sidewalk border and pole lights in the parking lot, they are
all high pressure sodium (HPS) and controlled by photo
sensors.
g. Building Shell: The building shell was described earlier; it
appears to be in good condition, inside and out. The single
overhead door not appear to be original, and is in good
condition. Man-doors and windows are all in very good
condition as well.
h. Motors: There are 15 large (5 HP or larger) motors in use in
this building, the highest power-consuming units being the (4)
main glycol circulation pumps (P10, 11, 18 and 19). The
elevator motor is the largest (30 HP) but its use is not
significant. Unfortunately, nameplates were not accessible
for any of the 10 AHU fan motors which are 5 HP or larger, so
no recommendations can be made regarding replacement
with high efficiency versions.. All 15 motors are listed in
Appendix D-2.
5. Historic Energy Consumption: Energy consumption is modeled within the
AkWarm-C program. The program typically analyzes twelve months of data.
Two year’s worth of natural gas energy (CCF”s) and electricity consumption
ENERGY AUDITS OF ALASKA ANCHORAGE POLICE DEPARTMENT HEADQUARTERS
June 28, 2012 Page 18 of 55
(KWh) were averaged then input into AKWarm-C. This monthly data is found in
Appendix F.
Energy consumption was analyzed using two factors: the Energy Cost Index
(ECI) and the Energy Use Index (EUI). The ECI takes the annual costs of
natural gas and electrical energy over the surveyed period of time (two years)
divided by the square footage of the building. The ECI for this building is
$4.02/SF, the ECI’s for two similar buildings, the Old City Hall and the Woodland
Park School (which is used as the Boys and Girls club administration
headquarters in Anchorage), are $2.07/SF, and $1.65/SF, respectively.
The energy use index (EUI) is the total annual average electrical and natural gas
energy consumption expressed in thousands of BTUs/SF. The average of the
2009 and 2010 EUI for this building is 176.6 kBTU/SF; the average 2009/2010
EUI for the Old City Hall is 129.8 kBTU/SF and 108 kBTU/SF for the Woodland
Park School. The average for Office Buildings across the US varies from 92 to
116 kBTU/SF as logged by the US Energy Information Administration. This
source data can be viewed at:
http://www.eia.gov/emeu/efficiency/cbecstrends/cbecs_tables_list.htm
6. Interactive Effects of Projects: The AkWarm-C program calculates savings
assuming that all recommended EEM that are modeled, are implemented in the
order shown in Appendix B. Some of the EEM’s listed in Appendix B noted as
“see Appendix D” are not modeled in AkWarm-C model due to limitations in
AkWarm-C’s capability. Therefore the savings calculated by AkWarm-C do not
take them into consideration, and visa versa. Furthermore, if the EEM’s
calculated by AkWarm-C are implemented out of order, savings for the
remaining EEMs will be affected, in some cases positively, and in others,
negatively. As a result of these anomalies, the overall building savings on the
first page of Appendix B may be over or understated.
In general, all projects were evaluated sequentially so that energy savings
associated with one EEM would not be attributed to another EEM as well. Best
efforts are made to model the recommended projects sequentially, so as to best
account for the interactive effects between the EEMs and not “double count”
savings.
Interior lighting, plug loads, facility equipment, and occupants generate heat
within the building. When the building is in cooling mode, these contribute to the
overall cooling demands of the building; therefore lighting efficiency
improvements will reduce cooling requirements on air conditioned buildings.
Conversely, lighting efficiency improvements are anticipated to increase heating
requirements slightly. Heating penalties are included in the lighting project
analysis that is performed by AkWarm-C.

7. Loan Program: The Alaska Housing Finance Corporation (AHFC) Alaska
Energy Efficiency Revolving Loan Fund (AEERLF) is a State of Alaska program
enacted by the Alaska Sustainable Energy Act (senate Bill 220, A.S. 18.56.855,
“Energy Efficiency Revolving Loan Fund). The AEERLF will provide loans for
energy efficiency retrofits to public facilities via the Retrofit Energy Assessment
for Loan System (REAL). As defined in 15 AAC 155.605, the program may
finance energy efficiency improvements to buildings owned by:
a. Regional educational attendance areas;
b. Municipal governments, including political subdivisions of municipal
governments;
c. The University of Alaska;
d. Political subdivisions of the State of Alaska, or
e. The State of Alaska
Native corporations, tribal entities, and subsidiaries of the federal government
are not eligible for loans under this program.

Appendix D
Additional, Building-Specific EEM details
WITH THE EXCEPTION OF D-1, THESE EEM’S ARE INTERACTIVE AND
DO NOT TAKE EACH OTHER INTO CONSIDERATION WHEN SAVINGS
ARE CALCULATED, SO THEY CANNOT BE ADDED CUMULATIVELY.
FURTHERMORE, INDIVIDUAL EEM SAVINGS WILL BE REDUCED (OR
INCREASED) DEPENDING ON WHICH EEM’S ARE SELECTED AND IN
WHAT ORDER THEY ARE IMPLEMENTED.
D-1: Plumbing fixtures: All urinals should be retrofitted or be replaced with ultra low
flow models. Urinals and faucets should have proximity sensing on/off controls.
Manually flushed toilets should be retrofitted with dual flush valves (see below). This
audit does not include water usage and AkWarm-C does not allow for the modeling of
it, but a typical faucet retrofit will result in 30% water savings and will payback in less
than 3 years. Ultra low flow urinals (1 pint to ½ gallon per flush) can save up to 66%
of water used, and typically pay back within 3 years. Dual flush toilet valves will
typically pay back within 1-3 years, depending on usage. These payback periods are
reduced by 66% or more if the fixture is replaced at its EOL rather than while it’s still
functioning. For an EOL replacement, the cost used is the incremental difference in
cost between an ultra-low-flow fixture and a straight across replacement with the same
fixture.
ENERGY AUDITS OF ALASKA ANCHORAGE POLICE DEPARTMENT HEADQUARTERS
June 28, 2012 Page 42 of 55
D-2: Motor replacements: It is generally recommended that all motors, 5HP or larger,
operating for 1500 hrs per year, or more, at continuous speed, be replaced at EOL with
premium efficiency motors. Motors operating for 5000 hours per year, or more, can be
replaced with premium efficiency motors prior to burn out, with a justifiable payback.
Motors in this building, 5HP and larger, are listed below, along with recommendations
for cost effective replacement at burn-out and for immediate replacement. There are
four instances in this building of cost effective motor replacement with premium
efficiency motors, prior to burn out.

Lighting Controls
Occupancy sensors sense the presence of occupants, turn the lights on at a pre-
determined level, and then turn the lights off after a programmed time period of no
occupancy. Line of sight, motion sensing occupancy sensors can be installed in
existing duplex switch boxes, as well as on ceilings. Dual technology sensors are
typically ceiling mounted in rooms, lavatories, corridors, vehicle bays and storage areas
where obstacles may interfere with line-of-sight sensors. The second technology in
these sensors activates lighting based on sound or changes in position, and work even
when a person is fully obscured by an obstacle. Zoned occupancy controls are
typically recommended for long corridors, large vehicle bays and large storage areas
with multiple switches and lighting zones. Zoned controls are designed to activate and
de-activate lighting by zone, by row, or even by fixture, based on the location of the
occupant. Occupancy sensors can reduce power consumption by 25-60%. Paybacks
on occupancy sensors range from 1 to 5 years, depending on the light fixture
consumption and occupancy of the room.
Lighting Management Systems (LMS) today have the capability to manage lighting
based on a wide variety of parameters including building usage, daylight conditions and
occupancy. They are retro-fittable, and can be stand alone or integrated into a
building’s HVAC DDC control system. Additionally, they can be easily re-configured
as a building’s usage or occupancy pattern changes.
Sample LMS systems and a sample high bay occupancy sensor (which could be used
for zone lighting control) follow.
