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
implied, or assumes any legal liability or responsibility for the accuracy, completeness,
or usefulness of any information, apparatus, product, or process disclosed, 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 this building occurred on September 11th, 2011.
Wainwright is a remote village of approximately 550 people located on the
Chukchi Sea about 70 miles southwest of Barrow. The Fire Station was
constructed in 1982 or 1983.
The building has an apparatus bay, a day room, small kitchenette, toilet rooms
and a shower, mechanical rooms, the Fire Chief’s office and a small itinerant
bunk room.
Building plans could not be located for this building, but it is identical to the
Atqasuk Fire Station (also audited by this auditor), so floor plans, lighting and
mechanical details were obtained from the Atqasuk Fire Station plans and
confirmed or supplemented by onsite observation.
The interior of this building is very well maintained, the exterior is in average
condition.
Energy Consumption and benchmark data
This building utilizes fuel oil for heating and electricity generated by the village
power plant.
Electrical benchmark data was provided by the North Slope Borough Utility
administration staff through Nortech Engineering, and appears to be reasonable
and consistent. Fuel oil data was provided by Olgoonik Corporation staff and
appears somewhat anomalous in 2012; see table 1 below.
Table 1
2010 2011 2012 3 yr average
Fuel Oil consumption (gallons) 2167 1970 3538 2558
Atqasuk 2 yr average: 2905 gallons
The subject building’s three year average is within 12% of the average
2009/2010 consumption of the Atqasuk Fire Station. The 2558 gallon annual
consumption for this building was normalized to a seasonal distribution (see
Appendix F) and the resulting 12 monthly consumption data points were then
used in AkWarm-C.
Summarized values for the 12 months of fuel oil and the average of 24 months
of electrical consumption are shown in Table 2 below:
ENERGY AUDITS OF ALASKA WAINWRIGHT FIRE STATION

Table 2

Consumption Cost Consumption Cost
Electricity ‐ kWh 46,980 $ 14,816 37,819 $ 11,546
Fuel Oil ‐ gallons 1,970 $ 10,421 3,537 $ 18,711
Totals $ 25,237 $ 30,257
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/square foot (SF). This number can then be
compared to other buildings to see if it is average, higher or lower than similar-
use 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
comparison buildings chosen were the Atqasuk Fire Station and the Barrow Fire
Station #2 – the auditor also performed the energy audits on these buildings.
The benchmark data for the comparison buildings was from 2009 and 2010 and
is averaged in Table 3.

** Data retrieved from the US Energy Administration database, these figures are for “Places of
Public Order and Safety”, the most relevant category tracked by the USEA.
Evaluation of energy consumption & benchmark data
Table 3 shows that the subject building’s EUI is 30%-38% lower than the two
very similar comparison buildings. Its ECI is very similar to the Atqasuk Fire
Station and dramatically lower than the Barrow Fire Station.
As is typical for Alaskan buildings, a comparison to similar buildings in the
continental US shows Alaska buildings have a higher EUI – which is to be
expected given the weather differences.

Fuel Oil (NG for Barrow)
Electrical EUI
A deeper investigation into the energy consumption of these three buildings
follows:
Chart 1
Chart 1 above shows the subject building’s gas and electrical EUI compared to
the two other similar use buildings.
Fuel Oil/Natural Gas consumption, EUI and ECI:
Having audited all three buildings, the auditor believes that the most likely
reason for the substantially lower fuel oil consumption and EUI for this building is
most likely inaccurate fuel oil benchmark data. There was no indication that this
building is any more efficient than the identical building in Atqasuk, and in fact,
the Atqasuk building is supplied with waste heat from the adjacent power
generation plant, although the valves were closed during the audit. The Barrow
Fire Station’s high NG consumption is attributed to a number of factors:
- The building has residences, which even though underutilized, they still
require some heat
- The OSA settings were found to be high
- The building has a substantially higher occupancy load, higher building
utilization, more and longer door openings and longer operating hours
The extremely low ECI for the Barrow Fire Station is attributed to the fact that
Barrow utilizes natural gas (NG) for heating. NG in Barrow costs $3.05/MMBTU
while fuel oil in Wainwright costs $38.33/MMBTU.

Electrical consumption:
Based on Chart 1, the subject building’s electrical consumption is not
remarkable.
Recommended Energy Efficiency Measures
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 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 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. Maintenance savings are included in the “estimated savings” figures
below. Table 4 at the end of this section summarizes these EEM’s and
Appendix B and Appendix D provide additional detail pertaining to each
individual recommendation.
ENERGY AUDITS OF ALASKA WAINWRIGHT FIRE STATION
May 30, 2012 Page 10 of 45
A.) SETBACK THERMOSTATS
A building-wide replacement of the existing low voltage adjustable
thermostats with 7-day digital programmable thermostats is
recommended. Night time and unoccupied temperatures should
be set back to 55F.
Appendices B-1 and B-3 provide additional detail for this EEM.
Combined Setback Thermostat EEM’s:
Estimated cost $ 3,300
Annual Savings $ 1,791
Payback 1.8 years
B.) OVERHEAD DOOR CLOSERS
Open overhead doors result in a large air infiltration of unheated
air. On a year round, average basis, rough calculations show that
for every one minute an overhead door is open, it costs
approximately $.75 in fuel oil to heat the infiltrating air. It is further
estimated that each door is open for at least 24 more hours/year
than is necessary to get vehicles in and out. This results in
$2161/yr in unnecessary fuel costs. It is recommended to add
automatic, timer based door closers and sensing devices (to
prevent inadvertent closing on a person or vehicle) to each door.
Appendix E shows sample devices and Appendix B-2 shows
financial detail.
Door Timer EEM:
Estimated cost $ 4,000
Annual Savings $ 2,083
Payback 1.9 years
C.) HEADBOLT HEATER CONTROLS
There are headbolt heater controls available that cycle the heater
based on outside air temperature. They result in an approximate
annual savings of 46%. See Appendix B-4 and Appendix E for a
sample specification. It is recommended to retrofit the existing
duplex outlets with these controls.
Headbolt Heater Control EEM:
Estimated cost $ 1,000
Annual Savings $ 455
Payback 2.2 years
ENERGY AUDITS OF ALASKA WAINWRIGHT FIRE STATION
May 30, 2012 Page 11 of 45
D.) DESKTOP COMPUTERS & DESK PLUG LOADS
Desktop PC’s consume between 180 and 250 watts when in use.
Laptops consume between 50 and 100 watts when in use. It is
recommended to replace the desktop PC’s with laptops at their
end of life (EOL) – even though the payback period is longer than
a typical laptop lifecycle. The incremental difference in cost
between a desktop and laptop is estimated to be $200. See
Appendix B-5.
Certain desk-related plug loads such as task lighting, printers,
computer monitors, etc. can be turned off automatically by using a
plug strip with an integrated occupancy sensor. When you leave
your desk area, this equipment will be turned off while a computer,
for example, can be left on. See Appendix E for an example of
such a device. Estimated cost for these devices is $125 ea,
estimated savings is very difficult to calculate, but anecdotal
evidence shows up to a 50% savings of desk-related plug
electrical consumption. The cost and savings for this device is not
included below, or in the AkWarm-C report in Appendix B.
Personal Computer EEM:
Estimated cost $ 600
Annual savings $ 83
Payback 7.2 years
E.) LIGHTING AND LIGHTING CONTROLS
It is recommended to upgrade the T12 fixtures in this building to T8
fixtures, to replace the metal halide (MH) fixtures in the apparatus
bay with T5 fixtures, and replace the HPS exterior fixtures with
LED fixtures. The only fixtures not recommended for an upgrade,
due to their very low usage, are the (2) 400 watt MH fixtures on the
building exterior. It is recommended to add occupancy sensors to
all rooms.
For the T12 to T8 retrofit, it is recommended to use a brand new
product released by Leviton, called “Zipline”. This retrofit kit
consists of a new set of “tombstones” with an integral instant start
electronic ballast. The retrofit labor is estimated at less than 15
minutes per fixture and the kit cost is less than $100. See
Appendix E for additional detail.
This EEM summarizes Appendix B-6 through B-10. See Appendix
E for more information on occupancy sensors, the “Zipline” retrofit
kit and energy saver 28 watt lamps.

Combined Lighting Control EEM’s:
Estimated cost $ 39,660
Annual Savings $ 3,460
Payback 11.5 years
A summary of the estimated cost totals and estimated annual savings
totals of the five (A. through E.) summary EEM’s listed above, is found in
Table 4 below, and again at the end of Appendix B.

Combined total of recommended EEM’s
summarized above:
Estimated total cost $ 48,560
Annual Savings (including
maintenance savings) $ 7,872

Does not include design or construction management costs
Operational Recommendations (ECM’s)
In addition to EEM’s, various Energy Conservation Measures (ECM’s) are
recommended. ECM’s are policies or procedures to be followed by
management and employees that require no capital outlay. ECMs
recommended 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.
(See sample plug load management device in Appendix E.)
4. Continuously re-commission the building: A building is a living
mini-ecosystem and its use changes. Re-evaluate building usage
at least annually and confirm that building set points, zones,
lighting levels, etc. are optimized for the current usage and
occupancy.
ENERGY AUDITS OF ALASKA WAINWRIGHT FIRE STATION
May 30, 2012 Page 13 of 45
5. 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.
6. 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
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 WAINWRIGHT FIRE STATION
May 30, 2012 Page 15 of 45
and J.P. Sheldon, all in Anchorage, were consulted for some of the lighting,
boiler, overhead door and 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 annual savings multiplied by the lifetime of the improvement, divided by
the initial installed cost. SIR’s greater than 1.0 indicate a positive lifetime
ROI.
The life-time for each EEM is entered into AkWarm-C; it is estimated based
on the typical life of the equipment being replaced or altered.
d. Limitations of the Study: All results are dependent on the quality of input
data provided, and may only act as an approximation. Most input data such
as building and equipment usage, occupancy hours and numbers, building
and HVAC operating hours, etc. was provided to the auditor by on site
personnel.
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.

who have contributed information that was used to prepare this report, including:
a. Alaska Housing Finance Corporation (Grantor): AHFC provided
the grant funds, contracting agreements, guidelines, and technical
direction for providing the audits. AHFC reviewed and approved the
final short list of buildings to be audited based on the recommendation
of the Technical Service Provider (TSP).
b. The North Slope Borough (Owner): The NSB provided building
sizing information, energy consumption data, building schedules and
functions, as well as building age.
c. Richard S. Armstrong, PE, LLC (Audit TSP): This is the TSP who
was awarded the projects in the Arctic Slope Regional Corporation,
Bering Straits area, and the Nana area. The firm gathered all relevant
benchmark information, cataloged which buildings would have the
greatest potential payback, and with the building owner, prioritized
buildings to be audited based on numerous factors, including the
Energy Use Index (EUI), the Energy Cost Index (ECI), the age of the
building, the size of the building, the location of the building, the
function of the building, and the availability of plans for the building.
They also trained and assigned their selected sub-contractors to the
selected buildings, and performed quality control reviews of the
resulting audits. They prepared a listing of potential EEMs that each
auditor must consider, as well as the potential EEMs that the
individual auditor may notice in the course of his audit. Richard S.

4. Building Description and Function:
The site visit and survey of subject building occurred on September 11th, 2011.
This single story building consists of 2593 square feet of apparatus bay and
2075 square feet of day rooms, offices and mechanical rooms for a total of 4668
square feet. The building is identical to a number of other fire stations in the
NSB.
The building was constructed on pilings using what appear (in the plans) to be
24” glue lam floor support beams. The floor is surfaced with 4x6 tongue and
groove decking. 8” structural insulation sub-floor panels are used, with sprayed-
in foam to fill gaps – the insulation value calculated by AkWarm-C is R-43.8.
Walls are pre-fabbed 6” structural insulated panels with metal siding and
finished with gypsum inside; AkWarm-C’s calculated insulation value is R-29.6
The roof is constructed of 8” pre-fabbed structural insulated panels with a
calculated insulation value of R-43.5, finished on the with exterior metal roofing
and gypsum on the interior. All windows are in excellent condition, vinyl, triple-
pane, and appear to have been upgraded from their original 1982 installation.
Building details are as follows:
a. Heating System: Heat is supplied by (2) Weil McLain 295
MBH, oil fired, 87% efficient, cast iron sectional boilers. Heat is
provided to perimeter rooms by hydronic baseboard fin tube
radiant heaters, valve and fan controlled by local, adjustable,
low voltage zone thermostats. Heat is provided to storage
spaces and vehicle bays via hydronic unit heaters which are
fan controlled by low voltage zone thermostats. HVAC controls
are via an electronic control system.
b. Ventilation: Ventilation is provided to the offices through the a
Logicaire air handler. Air handler heat is provided by hydronic
coils which are valve-controlled by a zone thermostat. There
are vehicle exhaust fans in the equipment bay, as well as a
make-up air unit and a large supply fan in adjacent rooms
(presumably interlocked to the exhaust fans). The toilet room
and shower room have exhaust fans shown on plans to
exhaust 170 CFM each.
c. Appliances: A commercial clothes washer and dryer are
located in the utility room. The set looks to be 10 years old, in
average condition, and appears to be heavily used for both
personal clothing and fire station related laundry. A ½ size
refrigerator, microwave and 2-burner electric range are located
in the day/break room; they support the itinerant housing in the
building. Additionally there is a full size residential type
refrigerator in the bunk room. 3 PC’s are in use in the building.
ENERGY AUDITS OF ALASKA WAINWRIGHT FIRE STATION
May 30, 2012 Page 18 of 45
d. Plumbing Fixtures: The building contains one toilet, one
lavatory sink, one kitchen sink, one utility sink in the vehicle bay
and two showers. All fixtures are manually operated and
appear to be post-1992. The toilet consumes 1.6 gpf and the
shower head’s at least 2.6 gpm. See Appendix G-1 for EEM
recommendations.
e. Domestic Hot Water: Hot water is provided to the showers,
lavatory and clothes washer by a 36 gallon, TrinagleTube
indirect fired hot water generator located in the boiler room.
.
f. Head Bolt Heaters: There are 4 head bolt heaters on the
south side of the building, all of which are suitable for retrofit.
They are typically used by employees during working hours
and for emergency medical vehicles.
g. Interior Lighting & Controls: This building has a mix of
interior lighting which includes T12 fixtures with magnetic
ballasts, metal halide fixtures, compact florescent and
incandescent bulbs. Exit signs are either battery powered, unlit
or self-luminous. Completion of a full lighting upgrade is
recommended in the AkWarm-C report in appendix B.
h. Exterior Lighting: Exterior lighting consists of 250 watt HPS
wall packs controlled by photo-sensors and two, seldom used
400 watt metal halide wall packs on the North side of the
building, on a manual switch.
i. Building Shell: The building shell appears to be in average
condition, although by today’s standards, it is under-insulated.
The high cost and relatively low ROI resulting from the addition
of insulation precludes a recommendation to increase the
insulation value of the shell at this time.
j. Living Quarters: Itinerant living quarters (the “bunk room”) are
used regularly.
k. Motors: There is only one large (5 HP or larger) motor in use
in this building. It is listed in Appendix C and was considered
and rejected for replacement with a premium efficiency motor.

5. Historic Energy Consumption: Energy consumption is modeled within the
AkWarm-C program. The program analyzes twelve months of data. Normally,
two year’s worth of fuel oil and electricity consumption are averaged then input
into AKWarm-C. As previously explained, three years of fuel oil data and two
years of electrical consumption data were used for this building. 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 energy cost index takes the annual
costs of fuel oil and electrical energy over the surveyed year, divided by the
square footage of the building. The ECI for this building is $5.94/SF, the ECI for
two very similar buildings, the Atqasuk and Barrow Fire Stations, are $5.29 and
$1.51 respectively.
The energy use index (EUI) is the total annual average electrical and heating
energy consumption expressed in thousands of BTU/SF. The EUI for this
building is 109 kBTU/SF; the average 2009/2010 EUI for the Atqasuk Fire
Station is 150 kBTU/SF and 175 kBTU/SF for the Barrow Fire Station. The
average for “Places of Public Order and Safety” across the US is 116 kBTU/SF
as logged by the US Energy Information Administration. This source data can
be viewed at: 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 are implemented in the order shown in
Appendix B. Appendix D-1 is 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 resulting from reductions in building
electrical consumption are included in the lighting 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 WAINWRIGHT FIRE STATION
May 30, 2012 Page 20 of 45
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
Appendix D-1: Plumbing fixtures: The lavatory faucet should be retrofitted with proximity
sensing on/off control valve. The toilet in this building uses 1.6 gallons per flush (gpf) with a
manual valve; it should be retrofitted with dual flush valve (see below). This audit does not
include water usage and AkWarm-C does not allow for the modeling of it, but a typical ultra low
flow urinal (1 pint to ½ gallon per flush) can save up to 66% of water used, and typically pays
back within 3 years, depending on usage. 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 or valve 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.

Appendix E – Specifications supporting EEM’s
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.
Step-Dim occupancy sensors turn on a portion of room lights (usually 1/3 or 2/3) upon
occupancy, and allow the occupant to manually turn on the rest of the lights. 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, alarm or other
control systems. 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.
