REPORT DISCLAIMERS
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 Statue 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, Alaska Housing Finance Corporation (AHFC), nor 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
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.

Guidance to the reader:
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 Alaska Housing Finance
Corporation’s (AHFC) Retrofit Energy Assessment Loans (REAL) program,
which is available to the building’s owner.
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, design to investigate further.
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 subject building occurred on February 7, 2012.
This building was originally constructed in 1986 as a Safeway grocery store
which was closed in 1992. Tenant improvements split the building in half and the
Municipality of Anchorage Data Storage / Management Unit is housed in the
east section of the building and the Anchorage Police Department (APD) utilizes
the west end for training purposes. There were mechanical upgrades to the APD
portion to accommodate two firing ranges in 1995. Server upgrades, including
electrical UPS enhancements, were done in 2002 and 2010.
The interior of the building is in average condition and the exterior is in good
condition, considering its age.
Energy Consumption and Benchmark Data
This building uses natural gas provided by Enstar Natural Gas Co. and
electricity provided by Chugach Electric Association, Inc. Benchmark utility data
for 2009 and 2010 obtained by the auditor, is summarized in Tables 1 and 2
below and presented in detail in Appendix E.
ENERGY AUDITS OF ALASKA APD TRAINING FACILITY / MISD CENTER
June 4, 2012 Page 8 of 51
Table 1
2009 2010
Consumption Cost Consumption Cost
Electricity - kWh 1,177,440 $ 140,627 1,130,000 $ 114,713
Natural Gas - CCF 78,421 $ 79,392 63,252 $ 53,968
Totals $ 220,019 $ 168,681
The electric service from this building is located on the Management Information
Systems Data (MISD) Center side of the building; power from there is fed to
APD training. There is no sub meter installed. In order to get an accurate cost
analysis of what each department is using in terms of electricity, and where
more exact energy savings can be made, it is suggested that a sub meter be
installed prior to power distribution to the APD side of the building.
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 1 above, electricity usage between 2009 and 2010 was
essentially unchanged while natural gas usage declined by 20%. This was most
likely due to a milder winter.
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 building management strategy, operations,
maintenance and/or safety
ENERGY AUDITS OF ALASKA APD TRAINING FACILITY / MISD CENTER
June 4, 2012 Page 9 of 51
All the EEMs considered for this facility are detailed in the attached AkWarm-C
Energy Audit Report (Appendix B). Each EEM includes payback times,
estimated installation costs and estimated energy savings.
The summary EEM’s that follow are the only EEM’s that are recommended
for this building. Others have been considered but are not deemed to be
justified or cost effective. The recommended EEM’s were selected based on
consideration from 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 thermostats - 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.). They are prioritized as a group, with the highest ROI
(shortest payback) listed first. Table 3 at the end of this section summarizes
these EEM’s and Appendix B (the AkWarm-C detailed report) and Appendix D
provide additional detail pertaining to individual recommendations.
A.) SETBACK THERMOSTATS
The control system for the offices is presumed to have
temperature setbacks already programmed into its system.
However, there seems to be a mixture of controls throughout the
building that may benefit from setback thermostats. It is
recommended to install setback thermostats in the Firing Range,
Directional Shooting, MISD office space, Fan Room, and
classrooms. This summary EEM combines the AkWarm-C retrofits
detailed in Appendix B, items 1-5 and 7. They reflect the
incorporation of unoccupied setback temperatures of 60 deg F in
appropriate spaces.
Combined Setback Thermostat EEM’s:
Estimated cost $4,200
Annual Savings $9,332
Payback 4.5 months
B.) REFRIGERATED VENDING MACHINES
There are two refrigerated beverage vending machines. The
vending machines should have a Vendingmiser (see
ENERGY AUDITS OF ALASKA APD TRAINING FACILITY / MISD CENTER
June 4, 2012 Page 10 of 51
www.vendingmiser.com) installed, which allows the vending
machines to go to an “idle mode” during non use periods. The cost
is minimal and payback is less than 2 years.
Refrigerated vending machine EEM:
Estimated cost of installed Vendingmisers $500
Annual Savings $400
Payback 1.2 years
C.) OTHER ELECTRICAL
It is recommended to replace the desktop personal computers with
laptop computers. Desktop PC’s consume between 200 and 300
watts when in use. Laptops consume between 50 and 100 watts
when in use. It is recommended to replace the 25 desktop PC’s
with laptops at their EOL. The incremental difference in cost is
estimated to be $200 each and although the payback is only
slightly less than the life expectancy of a laptop, the
recommendation is still made.
Summarized Other Electrical EEM:
Estimated cost $ 5,000
Annual Savings $ 1,058
Payback 4.5 years
D.) VFD’S ON FIRING RANGE AIR HANDLERS AND EXHAUST
FANS
It is recommended to add variable frequency drives (VFD’s) to EF-
1, EF-2, AHU-1 and AHU-2. See Appendix D for Yaskawa reports.
Variable Frequency Drive EEM’s:
Estimated cost $20,740
Annual Savings $3,879
Payback 5 years
E.) LIGHTING CONTROLS AND BULB UPGRADES.
Currently, there are several simple bulb upgrades that, along with
occupancy sensors, will offer a simple payback and energy
savings.
ENERGY AUDITS OF ALASKA APD TRAINING FACILITY / MISD CENTER
June 4, 2012 Page 11 of 51
Incandescent Bulbs: These should be replaced in the firing range
and directional shooting range with spiral compact fluorescent
lights (CFL’s).
Fluorescent Lighting Upgrades: Throughout the building there is a
myriad of different lighting. Typically all ballasts on the east side of
the building are magnetic, and those on the west side (APD) are
electronic, albeit some with T12 bulbs.
A complete lighting analysis should be done by a licensed
lighting/electrical engineer and the building should be upgraded to
high efficiency electronic ballasts with energy saving T8-28 watt
bulbs.
Lighting Controls: Occupant controls 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.
It is recommended to install motion sensing occupancy sensors
in the existing duplex switch boxes of all offices, corridors and
restrooms/locker areas. Dual technology sensors should be
installed where obstacles may interfere with line-of-sight sensors,
such as in lavatories, corridors, vehicle bays, and storage areas.
The second technology in these sensors activates lighting based
on sound. Zoned occupancy controls should be installed in long
corridors, large vehicle bays and large storage areas. Zoned
occupancy controls are designed to activate and de-activate
lighting by zone, by row, or by fixture based on the location of the
occupant. See Appendix E for sample occupancy sensors that
can activate a single or multiple fixtures. Occupancy sensors can
reduce power consumption by 25-60%. Paybacks on occupancy
sensors range from 1 to 3 years, depending on the light fixture
consumption and occupancy of the room.
This EEM combines Appendix B, items 9-19 and 21. See these
items for detailed cost estimates, savings and paybacks on the
specific lighting retrofits recommended.
Combined Lighting and Lighting Control EEM’s:
Estimated cost $116,500
Annual Savings $13,728
Payback 8.5 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. Turn 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.
4. Re-configure building occupants and activities to group un-
occupied offices (i.e. no tenant or staff using the space) or little
used spaces, into the same HVAC zone so that zone’s energy
consumption can be set back to minimal levels.
5. A building is a living mini-ecosystem and its use changes. Re-
evaluate building usage annually and confirm that building set
points, zones, lighting levels, etc. are optimized for the current
usage and occupancy.
6. Lamp consistency throughout a building improves operational
efficiency and lamp replacement should be a scheduled,
preventative maintenance activity. Re-lamp the entire building or
entire usage zones (a zone of the building that has similar lighting
usage, so lamps have roughly the same lifetime) as part of a
scheduled preventative maintenance routine. This assures all
lamps are the same color temperature (e.g. 2700K, 3000K, etc.)
which enhances occupant comfort and working efficiency. It also
minimizes expense because it is more cost effective to order large
quantities of the same lamp, and more labor efficient to dedicate
maintenance staff to a single re-lamp activity in a building zone,
rather than replace individual lamps as they fail.
7. Replace HVAC filters regularly. Maintain optimal operation of all
dampers, actuators, valves and other HVAC components.

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
heating, ventilating, and air conditioning (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. Brown Electric, Haakensen Electric, Proctor Sales, Pioneer Door,
ENERGY AUDITS OF ALASKA APD TRAINING FACILITY / MISD CENTER
June 4, 2012 Page 14 of 51
and J.P. Sheldon, all in Anchorage, were consulted for some of the lighting,
boiler, overhead door and air handling (respectively) 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 February 7, 2012. The
ambient outside temperature was 15F.
The building was erected in 1986 as a grocery store. It is typical slab on grade
construction with a 4-inch concrete slab reinforced with rebar and a 12-inch
footer around the perimeter. Wall construction is steel girders supporting 6-inch
pre-cast concrete panels spanning the full height of the building. Occupied
spaces are lined inside of the 6-inch concrete panels with a 3/4” air space, then
6-inch metal studs with R-19 insulation, vapor barrier, and 5/8” gypsum
(sheetrock). Interior walls were finished per the original schedule. Roof members
are shown as steel joists with a 1-1/2” metal deck and a 4-inch rigid insulation,
1/2" gypsum board, vapor barrier and cedar shingles.
Building details are as follows:
a. Heating System – Hydronics: Heat is provided in this
building by a variety of systems. The offices are receiving
conditioned air from two air handlers located in the
mezzanine area of the building on the APD side. Reheat coils
are installed in various location throughout both sides of the
building. Along perimeter offices there is radiant baseboard
heating and glycol unit heaters. Controls for the heating
system appear to be a mixture of partial digital controls
integrated with 28V thermostats. A complete controls analysis
should be done by a licensed controls engineer to evaluate
potential savings.
b. Cooling System: Plan schedules identify three (3) 5 ton, dry
coolers for server room cooling. It should be noted that at the
time of this report one unit has been replaced with a 10 ton
unit. Server cooling is the only cooling load assigned to the
building.
c. Ventilation: Ventilation and make up air is provided by the
two air handlers in the mezzanine section of the APD side of
the building.
d. Appliances: There are 2 older full size refrigerators located
in the lunch break room of the APD side and one on the
MISD side, there is also a ½ size refrigerator in the APD
break room. They are recommended for replacement with
Energy Star units at EOL in AkWarm-C; see Appendix B for
details.
ENERGY AUDITS OF ALASKA APD TRAINING FACILITY / MISD CENTER
June 4, 2012 Page 17 of 51
This building has approximately 25 PC’s in use which appear
to be replaceable at EOL with laptops. Secondary monitors
can be used with laptops where staff currently use two
monitors.
e. Plumbing Fixtures: This building contains a total of seven
(7) toilets, three (3) urinals, seven (7) lavatory sinks and five
(5) showers. All fixtures 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).
f. Domestic Hot Water: Hot water is provided to showers and
lavatories by a 125 gallon, direct gas fired State hot water
heater located in the boiler room. Just outside the boiler room
were, what appeared to be, (2) 80 gallon Amtrol indirect hot
water generators that are going to be installed at some point
as a replacement to the gas fired hot water heater.
g. Interior Lighting & Controls: This building has a mixture of
lighting. APD training, with exception of the fire range and
multi-directional shooting room, has older T-12 fixtures with
electronic ballasts. The firing range and multi directional
shooting rooms also had older T12 fixtures with electronic
ballasts, but also incorporate a large amount of incandescent
lighting and bulbs. The MISD side of the building had much of
the same lighting, but with older magnetic ballasts. It appears
that when the tenant renovations were done for APD, the
lighting and ballasts were upgraded to the most efficient at
the time of remodel.
Lighting Controls: None of the building’s rooms have motion
sensing occupancy installed in the existing duplex switch
boxes. There are no ceiling mounted, dual technology
sensors or zoned occupancy controls installed. The complete
building lighting upgrade should be completed by adding
these three types of sensors where appropriate, in the rooms
and spaces where manual switches or digital switch timers
are still in use. See Appendix D for additional information on
occupancy sensors.
All exit signs in the building are either unlit or self luminous
h. Exterior Lighting: Exterior lighting is HPS (High Pressure
Sodium) wall packs, and should be upgraded to LED wall
packs. All appear to be controlled by photo-sensors.
i. Motors: There is a large quantity and diversity of motors in
use in this building. Generally, motors of 5 HP and greater
ENERGY AUDITS OF ALASKA APD TRAINING FACILITY / MISD CENTER
June 4, 2012 Page 18 of 51
should be looked at for replacement with premium efficiency
motors. Appendix D identifies possible efficiencies to be
gained through motor replacements.
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 and electricity consumption were averaged then
input into AkWarm-C (see Appendix E).
Energy consumption was analyzed using two factors: the Energy Cost Index
(ECI) and the Energy Use Index (EUI). The energy cost index takes the annual
costs of 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
$4.56/SF; the ECI for the APD Headquarters Building is $4.02/SF.
The energy use index (EUI) is the total annual average electrical and heating
energy consumption expressed in thousands of BTUs/SF. The average of the
2009 and 2010 EUI for this building is 279 kBTU/SF; the average 2009/2010
EUI for the APD Headquarters Building is 177 kBTU/SF. The average for Office
buildings (the closest building category tracked by the US Energy Information
Administration www.eia.gov/emeu/efficiency/cbecstrends/cbecs_tables_list.htm),
in the Mid-West US, the coldest region in the continental US, is 176 kBTU/SF.
The US average is 212 kBTU/SF. (does not make sense…the coldest region is
lower than the US average?)
6. Interactive Effects of Projects: The AkWarm-C program calculates savings
assuming that all recommended EEM are implemented in the order shown in
Appendix B. Appendix D EEM’s are not included in the AkWarm-C model. If
some EEMs are not implemented, savings for the remaining EEMs will be
affected, in some cases positively, and in others, negatively.
In general, all projects were evaluated sequentially so that energy savings
associated with one EEM would not be attributed to another EEM as well. By
modeling the recommended projects sequentially, the analysis accounts for
interactive effects between the EEMs and does 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 AUDITS OF ALASKA APD TRAINING FACILITY / MISD CENTER
June 4, 2012 Page 19 of 51
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;

Lighting Controls
Occupant controls 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. 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. 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 3 years, depending on the light fixture
consumption and occupancy of the room.
A sample high bay occupancy sensor (which could be used for zone lighting control)
specification follows.
