REPORT DISCLAIMER
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 and well as
Illuminating Engineering Society (IES) recommendations. Wisdom and Associates, Inc. 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
Conservation Measures (ECMs), or the operating schedules and maintenance provided by the
owner. Furthermore, ECMs are typically interactive, so implementation of one ECM may
impact the cost savings from another ECM. Wisdom and Associates, Inc. and Central Alaska
Engineering Company accept no liability for financial loss due to ECMs that fail to meet the
forecasted payback periods.
This audit meets the criteria of a Level 2 Investment Grade Audit (IGA) per the American
Society of Heating, Refrigeration, Air-conditioning Engineers (ASHRAE) and the Association of
Energy Engineers (AEE), 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 of Alaska, and may be incorporated into AkWarm-C, the
Alaska Retrofit Information System (ARIS), or other state and/or public information
systems. AkWarm-C is a building energy modeling software developed under contract by
AHFC.

This audit was performed using 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. This can
be achieved through the wiser and more efficient use of energy. Opportunities for application of
these energy saving methods are discussed in detail throughout this report.
The average annual energy costs at this facility are as follows:
Electricity $55,287.00
Oil $144,636.96
Total $199,923

The potential annual energy cost savings for each energy conservation measure are summarized
in the executive summary along with a more detailed description in the energy conservation
measures section. All calculations are available in the support documentation. This audit is
consistent with an ASHRAE Level 2 audit. The evaluations are based on estimations and
industry standard calculation methods. The cost of each measure for this level of auditing is +/-
30% until detailed engineering, specifications, and hard proposals are obtained. More detailed
analyses would require engineering simulation models, hard equipment specifications, and
contractor bid pricing.
The comprehensive energy audit covers the 35,901 square foot school.
Utility information was collected and analyzed for 2 full year’s energy use of the building. The
utility information allows us to analyze the building’s operational characteristics and calculate
energy benchmarks for comparison to industry averages. A computer spreadsheet was used to
calculate benchmarks and to graph utility information (see the Benchmarking section).
An Energy Use Index (EUI) was established for the building. Energy Use Index (EUI) is
expressed in British Thermal Units/square foot/year (BTU/ft2/yr), which is used to compare
energy consumption to similar building types or to track consumption from year to year in the
same building. The EUI is calculated by converting the annual consumption of all energy sources
to BTU’s and dividing by the area (gross square footage) of the building. Blueprints and
drawings are utilized to verify the gross area of the facility. The EUI can be a good indicator of
the relative potential for energy savings. A low EUI indicates less potential for energy savings,
while a high EUI indicates poor building performance, therefore, a high potential for energy
savings.
The site survey provided information for interpreting where energy was spent and finding energy
savings opportunities within the facility. The building site visit was performed to survey all
major building components and systems. The site visit included an inspection of energy
consuming components.

The ECM# is the priority ranking of an Energy Conservation Measure.
The Installed Cost is the full upfront cost expected for the improvement.
The Annualized NPV Savings reflects the annualized Net Present Value savings over the life of
the improvement, adjusted for general inflation, fuel price escalation, maintenance, discount rate
and installed cost.
The NPV Savings Over Improvement Life reflects the Net Present Value of cumulative savings
over the life of the improvement, adjusted for general inflation, fuel price escalation,
maintenance, discount rate and installed cost.
The Breakeven Cost is the maximum cost in today’s dollars that could be spent on an
improvement and still be cost effective.
The Savings to Investment Ratio (SIR) is a life-cycle cost measure calculated by dividing the
total savings over the life of a project (expressed in today’s dollars) by its investment costs. The
SIR is an indication of the profitability of a measure; the higher the SIR, the more profitable the
project. An SIR greater than 0 indicates a cost-effective project (i.e. more savings than cost).
The Return on Investment (ROI) listed for each ECM is the net savings of the energy
conservation measure divided by the installed cost listed.
The Simple Payback listed for each ECM is the number of years required to break even on the
investment, adjusted for general inflation, fuel price escalation, maintenance, discount rate and
installed cost.
The total savings listed for cost effective measures and all measures are for estimation purposes
only and cannot be considered 100% accurate because of the interrelation of the ECMs.

Method of Analysis
Post site visit work included an evaluation of the information gathered, researching possible
conservation opportunities, organizing the audit into a comprehensive report, and making
recommendations on HVAC, lighting, and building envelope improvements. Collected data was
processed using Microsoft Excel spreadsheets and ASHRAE energy calculations to anticipate
energy usage for each of the proposed energy conservation measures (ECMs). The actual
building energy usage was entered directly from the utility bills provided. The anticipated energy
usage was compared to the historical data to determine energy savings for the proposed ECMs.
It is important to note that the savings represented in this report should not be considered
additive because of the interrelation of energy conservation measures. Implementation of more
than one ECM often affects the savings of other ECMs.
ECMs were determined by identifying the building’s unique properties and finding the most
beneficial energy saving measures available that met the specific needs of the facility. The
building construction type, function, operational schedule, existing conditions, and foreseen
future plans were accounted for in the evaluation and final recommendations. Energy savings are
calculated based on industry standard methods and estimations. Energy consumption is
calculated based on manufacturer’s information when new equipment is proposed.
Cost savings are calculated based on the actual historical energy costs for the facility. Installation
costs include materials and labor costs to estimate the full up-front investment required.
Measures were analyzed based on life-cycle-cost techniques, which include the initial cost of the
improvement, expected life of the improvement, annual energy cost, annual maintenance cost,
and a discount rate of 3.0%/year. Energy cost escalation rates are taken from the current Energy
Price Indices and Discount Factors for Life-Cycle Cost Analysis from the US Department of
Commerce. Maintenance costs are estimated at 2% of fuel cost related to an improvement unless
otherwise noted. Expected life of improvements is taken from industry and government sources.
Future savings are discounted to the present to account for the time-value of money (i.e. money’s
ability to earn interest over time).
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. The design professional or other persons
following the recommendations shall accept responsibility and liability for the results.

Audit Overview/Building Description
The Seldovia School has been in place in one form or another since before records are available.
The earliest records available are from a 1957 As-Built survey. Known additions took place in
1971 and 1983. This building is heated by two oil fired boilers that also provide the domestic hot
water, and served by two main air handling units with a number of cabinet unit heaters in the
older building sections. Wall construction is composed of concrete with some area un-insulated.
Ceiling insulation varies from two to six inches of rigid board. This school also houses a small
pool that is heated off of the boiler system.
Interior lighting is provided by T8 fluorescent fixtures and metal halide lights. Exterior lighting
is provided by high pressure sodium lighting.
Because of the remoteness of the location of this building an additional cost factor has been
added to the projected costs, based on the Alaska Department of Education and Early
Development Geographic Area Cost Factor.
This building has an electrical demand meter and demand KW usage was noted in the
benchmark information provided. However, no demand cost was provided with the benchmark
information. If this building is in fact being assessed a KW demand charge that will increase the
savings of the electrical improvements. This report can be re-figured with new paybacks if a
demand charge rate is available.

Energy Conservation Measures
Energy conservation measures are those measures which are considered as having the potential
to be cost effective and appropriate energy improvement options for the building. Estimated
costs are taken from the current Craftsman National Estimator and are adjusted for zip code.
Different rates and averages can be applied to this report if requested.
Lighting and electrical improvements are based on usage estimates apparent at the time of the
audit and may not reflect actual usage or occupant behavior. Before committing to a complete
lighting retrofit, it is recommended that a small sample of the new lamps you intend to use be
installed and tested for a time before pursuing all of the recommended changes. Light output,
color rendition, color temperature and personal preference all play a part in a satisfactory lighting
retrofit. The benefit of reduced energy consumption is lost if fixtures have to be re-lamped after
the retrofit or people are not comfortable with a new lighting scheme.

Operations and Maintenance Measures
Staff Training – Visit www.energystar.gov for free training materials and courses on energy
conservation and awareness for building staff. Live web conferences, animated presentations and
pre-recorded trainings are just some of the tools available. Creating an inclusive strategy that
establishes roles and actions throughout the organization can help to integrate good energy
management practices. When developing an action plan, consider brainstorming with various
departments to identify ways they can contribute.
Portfolio Manager – Consider utilizing EPA’s Portfolio Manager, which is an online system that
allows building personnel to track building performance and improve energy efficiency across
multiple buildings. You can also contact your energy auditor for additional information about
this program. See www.energystar.gov
After Hours – The building manager/operator should be tasked with turning off all non-essential
equipment at night, on weekends, or during other non-occupied times. Power strips can be turned
off during off hours; also power strips can be connected to timers or occupancy sensors. Smart
power strips with built-in occupancy sensors or activity sensors are available.
Plug Loads – Plug loads use up to an estimated 20% of electrical energy in commercial
buildings. Most plugged in devices consume energy even when off. Power is drawn by devices
in passive standby, such as a computer in “sleep” mode or a clock on a microwave, and active
standby such as when a screen saver is on a computer screen or television screen. The majority
of plug loads come from office equipment (computers, printers, copiers, etc.) and appliances
(refrigerators, coffee machines, etc.). As equipment deteriorates or is scheduled for replacement,
it is recommended that it be replaced with EnergyStar certified equipment.
Refrigeration – Most refrigerators, freezers, ice makers and other types of cooling equipment can
benefit from cleaning the evaporator coils. This should be done on a yearly basis to reduce
electrical costs.
Air Handlers – Filters and coils should be cleaned/replaced periodically to ensure proper airflow.
Dirty filter/coils decrease heat transfer ability and efficiency of the system. Belts should be
checked regularly and tightened when necessary.
Controls – The building operational systems are currently controlled by a combination of direct
digital controls and pneumatic controls. Controls on a building of this type can be one of the
largest savers or wasters of energy, depending on how the controls are setup and maintained.
Annual calibration, maintenance and updates are essential to a properly performing system that
saves money.

Benchmark Information
Benchmarking and analysis of the utility bills was used to collect data about the building in terms
of energy usage patterns, consumption, and comparison with similar buildings. Benchmarking
was used to identify energy usage patterns and trends that showed a need for specific
investigation of certain systems. Benchmarking also identified potential issues in how the
building is operated which may lead to energy savings. Analysis of utility data provides a context
for the audit.
The BTU usage of the building per square foot is more than double more the national average of
similar buildings. This is larger than expected and points to opportunities for energy usage
reduction.
Energy Audit Report
April 16, 2012
pg. 32
Electrical usage in terms of BTU per square foot is 7% lower than the national average. This is good but
the high cost per KWH of electricity makes pursuing reductions in electrical usage worthwhile. It also
illustrates that oil consumption accounts for the high overall BTU per square foot load compared to the
benchmark on the previous page.
Energy Audit Report
April 16, 2012
pg. 33
Oil usage in terms of BTU per square foot is 486% higher than the national average. This is much higher
than normal and points to great savings opportunities, especially considering the high cost per BTU of
fuel oil in this community.
Energy Audit Report
April 16, 2012
pg. 34
The total energy use profile shows the majority of BTUs consumed by the building are from oil which is
used exclusively for heating. Electrical usage is second. This ratio of oil to electrical use is unusually high
and points to savings opportunities in heating and insulation.
Energy Audit Report
April 16, 2012
pg. 35
The energy cost total shows that oil is the majority fuel cost, which is not surprising considering the
amount of oil consumed by this building.
Energy Audit Report
April 16, 2012
pg. 36
Electrical consumption has declined slightly over the benchmark period. This building also has a
significant base load in the summer.
Energy Audit Report
April 16, 2012
pg. 37
Oil consumption tracks with heating degree days, which are a measure of the heating load imposed on the
building by the climate.

Install controls to regulate pool temperature. Pool temperature
set back for un-occupied times to average 2 degrees less
overall. Year round operating conditions are unknown,
estimated water and air temperatures and relative humidity are
taken from mean ASHRAE figures. Pool logs or other data
which were not avaliable during the site-audit would allow for
