REPORT DISCLAIMERS
The information contained in this report, including any attachments, is
intended solely for use by the building owner and the AHFC. No others
are authorized to disclose, copy, distribute or retain this report, in whole or
part, without written authorization from Richard S. Armstrong, PE, LLC,
2321 Merrill Field Drive, C$6, Anchorage, Ak 99501. Additionally, this
report contains recommendations that, in the opinion of the auditor, will
cause the owner to realize energy savings over time. All
recommendations must be designed by a registered engineer, licensed in
the State of Alaska, in the appropriate discipline. Lighting
recommendations should all be first reviewed by running a lighting
analysis to assure that the recommended lighting upgrades will comply
with State of Alaska Statue as well as IES recommendations.
Payback periods may well vary from those forecast due to the uncertainty
of the final installed design, configuration, equipment selected, and
installation costs of recommended Energy Efficiency Measures (EEMs), or
the operating schedules and maintenance provided by the owner.
Furthermore, EEMs are typically interactive, so implementation of one
EEM may impact the cost savings from another EEM. Neither the auditor,
Richard S. Armstrong, PE, LLC, AHFC, or others involved in preparation of
this report will accept liability for financial loss due to EEMs that fail to
meet the forecasted payback periods.
This audit meets the criteria of an Investment Grade Audit (IGA) per the
Association of Energy Engineers definition, and is valid for one year. The
life of the IGA may be extended on a case$by$case basis, at the discretion
of the AHFC.
IGSs are the property of the State, and may be incorporated into AkWarm$
C, the Alaska Energy Data Inventory (ARIS), or other state and/or public
information system

Barrow Heavy Equipment Maintenance Shop
1. Executive Summary: The Barrow Heavy Equipment Maintenance
Shop is estimated to have been originally constructed in 1983, but it
underwent a ventilation and heating upgrade in 1994 based on plans
for the remodel/addition project. The facility contains six heavy
equipment repair bays, 5 offices, a break room, as well as
mezzanine storage. The two end bays have a 26’ height and a door
on each end of each bay, as compared to the other 4 bays that have
an 18’ height and only one door per bay. See plans attached. The
building is in generally good condition. The 2009 and 2010 annual
utility energy consumption reported by BUECI for this building is
displayed in Table 1 below. This data is different from the data
presented by Nortech because they combined all four shop
buildings, whereas this data represents the actual gas consumption
for the Heavy Equipment Shop on 3427 C Street with the
Warehouse on 3425 C Street since both are on the same gas meter.
There are separate electric meters, so the electric data is for this
building only.

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
about 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 listed in Table 2 below:

The natural gas consumption
is very high, but it is believed
that the use of a gas fired
“Hotsy” is the reason for the
high consumption. This
supposition is confirmed by
the very high water
consumption during summer
months when equipment
washing would occur using
hot water generated by the “Hotsy”.
Various Energy Efficiency Measures (EEMs) have been analyzed for
this building to determine if they would be applicable for energy
savings with reasonably good payback periods. Those EEMs that
have a payback period of less than 8 years, or those that are
recommended for code compliance, life cycle replacement, or other
reasons are also included. Also, where a lighting upgrade is
recommended from T$12 lamps with magnetic ballasts to T$8 lamps
with electronic ballasts, then the entire facility should be re$lamped
and re$ballasted to maintain a standard lighting parts inventory,
regardless of the payback. For example, a storage room that is
infrequently used may not show a very good payback for a lighting
upgrade, but consistency dictates a total upgrade.
Specific EEMs recommended for this facility are detailed in the
attached AkWarm Energy Audit Report along with specific payback
Barrow Heavy Equipment Maintenance Shop Comprehensive

6
times, as well as estimated installation costs and estimated energy
savings. The higher priority items are summarized below:
a. Flourescent Lighting Upgrades: In general, all of the T$12
flourescent lamps, and all of the magnetic ballasts
throughout the building should be replaced with new T$8
lamps with electronic ballasts. Typical savings in power
consumption varies 10$30% with this upgrade.
b. Lighting Control Upgrades: Many lights were found to be
left on with nobody in the space. Occupant controls can
sense the presence of workers, and turn the lights on. The
controller can then turn the lights off after a programmed
time period of no occupancy. These controls can reduce
total kWh consumption for the lighting in the order of 30$
90%, depending on the amount of time the lights are
manually left on.
c. Shop Lighting Upgrades: The shops are lit with high
intensity discharge 400 watt HPS lights, 20 fixtures. It is
recommended that all fixtures be replaced with new 6$lamp
high output fluorescent fixtures that can be switched with
occupancy sensors. While the power consumption may rise
slightly, the on time will be reduced, which would result in
an overall shop lighting energy reduction of about 23%.
d. Exterior Lighting Upgrades: The exterior high pressure
sodium lights operate during periods of darkness, which is
about half of a year. It is estimated that the use of LED
exterior lights can reduce the power consumption by 60%.
e. Setback Thermostats in all spaces: The thermostats were
found to be set to 72 degrees F, 24/7. It is recommended
that lockable setback thermostats be installed and
programmed for occupied temperatures of 72 deg F, and
unoccupied temperatures of 60 deg F. This has an
estimated payback of 0.4 years for the building,
f. Ventilation: It is recommended that six destratification fans
be installed in the shop to put the heat down on the floor
level and reduce heating stratification near the ceiling. The
estimated payback for theis is 7.6 years.
g. Refrigerator: Newer Energy Star refrigerators use about
411 watts, compared to 1990 versions that used 1,044
Barrow Heavy Equipment Maintenance Shop Comprehensive
Energy Audit
7
watts. While this would have a 7.4 year payback, it is still
recommended due to the relatively low cost and quick
payback.
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:
• Turn off lights when leaving a room that is not controlled by an
occupancy sensor that automatically turns off lights.
• Turn off computers, monitors, printers, faxes, coffee makers,
etc when leaving the office for the day.
• Keep overhead doors closed except when they are required to
be open for movement of vehicles.
The 11 priority recommendations in the detailed report estimate to save
$8,082/year, with an installed cost of $71,980, for a 8.9 year payback.
This does not include design or CA services, but overall it does indicate
a cost effective energy savings program.
2. Audit and Analysis Background:
a. Program Description: This audit included services to identify,
develop, and evaluate energy efficiency measures at the
subject building. The scope of this project included evaluating
the building shell, lighting, other electrical systems, and
heating, ventilating, and air conditioning (HVAC) equipment.
Measures were selected such that an overall simple payback
period of 8 years or less could be achieved.
b. 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 (roof, windows, etc)
ii. Heating, ventilating, and air conditioning
Barrow Heavy Equipment Maintenance Shop Comprehensive
Energy Audit

iii. Lighting systems and controls
iv. Building specific equipment
v. Plumbing systems
c. Method of Analysis: The information gathered prior to the site
visit and at the site visit is entered into AkWarm$C, an energy
modeling developed for Alaska Housing Finance Corporation
(AHFC) specifically to identify forecasted energy consumption
which can be compared to actual energy consumption.
AkWarm$C also has some pre$programmed EEM retrofit
options that can be analyzed with energy savings forecasted
based on occupancy schedules, utility rates, building
construction type, building function, existing conditions, and
climatic data that is already uploaded to the program based on
the zip code of the building. When new equipment is
proposed, energy consumption is calculated based on
manufacturer’s cataloged information.
Cost savings are calculated based on the historical energy
costs for the building. Installation costs include labor and
equipment to estimate the full up$front investment required to
implement a change, but design and construction management
costs are excluded. Costs are derived from Means Cost Data,
industry publications, experience of the auditor, local
contractors and equipment suppliers. Haakensen Electric was
consulted for some of the lighting retrofit costs. Maintenance
savings are calculated were applicable and are added to the
energy savings for each EEM.
The cost and savings are applied and a simple payback and
simple return on investment (ROI) is calculated. The simple
payback is based on the number of years that it takes for the
savings to pay back the net installation cost (Net Installation
divided by Net Savings.)
A simple life$time calculation is shown for each EEM. The life$
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$time of the EEM. The total
Barrow Heavy Equipment Maintenance Shop Comprehensive
Energy Audit
9
energy savings is calculated as the total life$time multiplied by
the yearly savings.
d. Limitations of the Study: All results are dependent on the
quality of input data provided, and can only act as an
approximation. In some instances, several methods may
achieve the identified savings. This report is not intended as a
final 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 measure, but these costs generally run
around 15% of the cost of the work.
3. Acknowledgements: We wish to acknowledge the help of
numerous individuals 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. North Slope Borough (Owner): The NSB provided building
sizing information, two years energy billing data, building
schedules and functions, as well as building age.
c. Nortech Engineering (Benchmark TSP): Nortech
Engineering compiled the data received from the NSB and
entered that data into the statewide building database, called
the Alaska Retrofit Information System (ARIS).
d. 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 provided
Barrow Heavy Equipment Maintenance Shop Comprehensive
Energy Audit
10
to them by Nortech, cataloged which buildings would have the
greatest potential payback, and 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 their selected sub$contracted
auditors, assigned auditors to the selected buildings, and
performed quality control reviews of the resulting audits. They
prepared a listing of potential EEMs that each auditor must
consider, as well as the potential EEMs that the individual
auditor may notice in the course of his audit. Richard S.
Armstrong, PE, LLC also performed some of the audits to
assure current knowledge of existing conditions.
e. Energy Audits of Alaska: This firm has been selected to
provide audits under this contract in addition to RSA
Engineering. The firm has two mechanical engineers, certified
as energy auditors or professional engineers.
4. Building Description and Function: The subject building is called
the Barrow Heavy Equipment Maintenance Shop. It was originally
constructed in 1983, and had a remodel constructed in 1994. The
building has one story, with a mezzanine on one side and at the rear.
a. Heating System: The building heating system consists of two
Weil McLain 1,674 MBH cast iron gas fired boilers. The boilers
provide heat to six vertical unit heaters, baseboard in the
offices, and air handlers.
b. Ventilation System: There are large exhaust fans, air
handlers, and gas make up air heaters in the building to
provide ventilation. A specialty carbon monoxide fan provides
exhaust for products of combustion when vehicles are
operated for tune$up.
c. Plumbing System: Toilets with lavs are provided for the
workers.

d. Domestic Hot: How water is generated using a 40 gallon
electric hot water heater.
e. Lighting: Typical lighting throughout the building is comprised
of T$12 fluorescent fixtures, using magnetic ballasts. Exterior
lighting utilizes 250 watt high pressure sodium (HPS) wall
packs, in addition to existing lighting on the older section.
5. Historic Energy Consumption: Energy consumption is modeled
within the AkWarm$C program. The program only analyzes 12
months of data, so where 24 months of data are available, the data
is averaged and input to AkWarm$C to provide more accuracy. The
energy consumption data is presented and graphed in the attached
AkWarm$C program results.
Energy consumption was analyzed using two factors: the Energy
Cost Index (ECI) and the
Energy Use Index (ECU).
The energy cost index
takes the average cost of
gas and electrical energy
over the surveyed period
of time (typically 2 years)
and averages the cost,
divided by the square
footage of the building.
The ECI for this building is $ 1.92, and the average ECI for all
buildings in Barrow that were surveyed is $ 1.68/SF. Fire Station #2,
a newer facility in adjacent Browerville has an ECI of $1.51.
The energy use index (ECU) is the total average electrical and
heating energy consumption per year expressed in thousands of
BTUs/SF. The average EUI for all buildings in Barrow that were
surveyed is 211 kbtu/sf, and the EUI all four of the C Street Shops is
162 kbtu/sf, compared to 175 for Fire Station #2.
6. Energy Efficiency Measures considered or recommended: The
building was examined for application of a multitude of potential
EEMs that are discussed below. Those EEMs that appear to have
Barrow Heavy Equipment Maintenance Shop Comprehensive
Energy Audit
12
an application for the subject building are further analyzed for
estimated payback periods, either within the AkWarm$C program or
separately within this report. The accuracy of the cost estimates and
paybacks varies significantly due to a multitude of conditions, but is
estimated to be approximately +/$ 25%. Assumptions made
regarding energy costs and the life of the EEM, noting that post$
construction measurement and verification are based on energy
savings, not energy cost savings.
Many of the selected EEMs are analyzed within the AkWarm$C
program using the schedules and estimated costs input into the
model.
7. Interactive Effects of Projects: The AkWarm$C program
calculates savings assuming that all recommended EEM are
implemented. If some EEMs are not implemented, savings for the
remaining EEMs will be affected, in some cases positively, and in
others, negatively. For example, if the fan motors are not replaced
with premium efficiency motors, then the savings for the project to
install variable speed drives (VFDs) on the fans will be increased.
In general, all projects were evaluated sequentially so that energy
savings associated with one EEM would not be attributed to another
EEM as well. For example, the night setback EEM was analyzed
using the fan and heating load profile that will be achieved after
installation of the VFD project is completed. 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.
