This Post Installation Report summarizes the results of an Ameresco Energy Audit of the Village of
Shageluk, the initial energy savings measures identified and proposed, and any changes that may have
occurred throughout the installation process. The Village of Shageluk is a recipient of an Alaska Energy
Authority (AEA) Village Energy Efficiency Program (VEEP) grant of $100,000.
Ameresco subcontracted this energy audit to Whitney Construction. Eric Whitney conducted the energy
audit on December 1-2, 2010.

The audit identified existing types, conditions, operating modes, and energy consumption profiles for a
variety of buildings, facilities and systems. The audit also identified all cost-effective system and facility
modifications, adjustments, alterations, additions, and retrofits. Systems investigated during the audit
included heating, ventilation, interior and exterior lighting, process exhaust, domestic hot water, motors,
building envelopes, utility metering systems, and energy management control systems (EMCS).
The table below shows the results of Ameresco’s audit and potential calculation savings, allocated by
grant. See Appendix A for more detailed calculation results. Project costs include costs incurred from the
site visit, engineering time, materials cost, and labor cost, as well as Ameresco’s markup. It is important
to note that the simple paybacks (SPBs) have been determined according to ECO type. For example, the
SPB for an electrical ECO is calculated using only the annual kWh savings, even though the equivalent
annual fuel gallon monetary savings is reported.

Description: The City Office building is a two-story log cabin-style building that was originally
constructed in the 1980’s. This building houses the city offices, rental bedrooms, and a rental office
space.
General Conditions: The building is in fair condition, and its structural integrity is currently in question.
Pictures of general conditions found during the field audit immediately follow this building description.
Building Envelope: The building structure is in fair condition overall. In the summer of 2009, some
structural work was completed; two 6 by 6 foot posts were installed in an effort to stabilize the second
floor. The floors are not level in some areas, and some of the logs are currently showing signs of rotting.
Heating: Space heating is provided by a Riteway model LF20 fuel oil furnace. This furnace is an old
combination wood- and oil-burning furnace, and its estimated efficiency is 70%. Although this furnace
can be wood-burning, the village has not used it in this capacity in many years.
Controls: Building heating zones are controlled by mechanical thermostats.
Lighting: Interior lighting consists primarily of T12 fluorescent lamps with magnetic ballasts. There are
no occupancy sensors in the building.

11..22 SSHHAAGGEELLUUKK WWAASSHHEETTEERRIIAA
Description: The Washeteria building houses the village’s laundering equipment and also serves
as the water treatment facility. Aside from the laundering equipment, the Washeteria also houses
showers, bathrooms, and a sauna.
General Conditions: The building was originally constructed in 1994 and is in good condition
overall.
Pictures of general conditions found during the field audit immediately follow this building
description.
Building Envelope: The building is in good condition overall, though the exterior shows many
signs of weathering. It is adequately insulated overall, with engineered foam panel walls and
ceiling.
Heating: Heating for the Washeteria is provided by two Burnham model V8 boilers. Whitney
Construction noted that these boilers are greatly oversized to meet building heating needs, unless
these boilers are also heating the water lines to the Post Office, Clinic, and City Building as well.
The mechanical room of the building is usually uncomfortably warm due to the excess heat from
the boilers, and occupants frequently leave windows open to remedy this.
Controls: Building heating is controlled by a mechanical thermostat.
Lighting: Interior lighting fixtures are mostly T12 fluorescent with magnetic ballasts. There are
no occupancy sensors in the facility.

Domestic Water: The Washeteria has a new solar water heating system, but this system was not
operational at the time of the audit. This system has not been in operation long enough to
produce any legitimate data for study on the effectiveness of the system.

11..33 SSHHAAGGEELLUUKK SSCCHHOOOOLL
Description: The Shageluk school houses elementary through high school students. This building was
audited for a lighting survey only, though other observations from the walkthrough have been reported.
Lighting: Interior lighting is primarily T12 fluorescent fixtures with magnetic ballasts. The gym area is
light by high bay mercury vapor (MV) fixtures.
Windows: During the walkthrough, the auditor found many of the windows at the school are failing and
do not shut properly. Upon further investigation, the windows are good quality triple pane fixtures with
low-e coatings, but the hardware currently used is inadequate to support the weight of the triple pane
glass. The school district should contact the manufacture to remedy this defective product.

The City of Shageluk purchases its electricity from the Alaskan Village Electric Cooperative (AVEC).
Village facilities are billed on an electric use and fuel use to provide the electricity. Some facilities may
also qualify for a Power Cost Equalization (PCE) incentive. The AVEC rates for the City of Shageluk are
listed below.
Current Rates as of January 2011
AVEC Cost of Fuel (Added to Customer Electric Bill) $ 0.2721
Rate Per kWh, Fuel Cost Included (1-700 kWh) $ 0.5721
Rate Per kWh, Fuel Cost Included (Over 700 kWh) $ 0.4721
PCE Rate (1-700 kWh) $ 0.3546
PCE Rate (700+ kWh) $ 0.3282
Rates August 2010 - December 2010
AVEC Cost of Fuel (Added to Customer Electric Bill) $ 0.2634
Rate Per kWh, Fuel Cost Included (1-700 kWh) $ 0.5634
Rate Per kWh, Fuel Cost Included (Over 700 kWh) $ 0.4634
PCE Rate (1-700 kWh) $ 0.3464
PCE Rate (700+ kWh) $ 0.3195
Rates for Calculations, Including Fuel Cost and PCE Incentive
Rate for Calculations (1-700 kWh) $ 0.2175
Rate for Calculations (700+ kWh) $ 0.1439
The Shageluk School is assumed to have the same utility rates as the rest of the village because the
school’s utility bills were not readily available. Based on commonalities between the other villages under
AVEC, however, a $45/kW charge has been considered for electrical ECOs at the school.

The Village of Shageluk purchases its fuel at a rate of $5.65/gallon. In 2009, the City Office building
used 2,000 gallons of fuel. In the same year, the Washeteria used 5,000 gallons of fuel.

The village has a number of designated maintenance personnel that seem to possess the basic skills
required to clean and maintain selected equipment. From Ameresco’s observations, if the equipment
should fall into disrepair, the staff does not have the training or experience to repair the equipment per the
manufacturer’s requirements and tends to piece together the equipment to maintain operation. Over time,
the systems no longer function as required, which currently appears to be the case of most equipment and
systems with in the village.
Operations and maintenance is one area in energy services where improvement and training costs are
lower than equipment replacement costs, and the energy efficiency return is high. During the site audit,
Ameresco found that outside of general cleaning, most of the equipment is not maintained to meet
standard manufacturers’ recommendations. Dirty filters, boilers in disrepair, systems altered, and control
systems disconnected are a result of limited funding and lack of system training. This results in excessive
energy use, premature equipment failure, and employee and resident discomfort. An annual system check
by a qualified burner service technician to perform services such as boiler cleaning, boiler tune ups,
system check out, and control system reviews will not only extend the overall life of the equipment, but
improve occupant comfort as well as increase and maintain long term energy efficiency.

44..11..11 EElleeccttrriiccaall OOppppoorrttuunniittiieess
E01 – T8 Lighting Upgrade
This ECO proposes replacing current T-12 fluorescent lighting and magnetic ballast with T-8 lamps and
electronic ballasts. Post-light levels will be nearly equal or better to that of the existing lighting systems,
E02 – T5 Lighting Upgrade
This ECO proposes replacing high intensity discharge (HID) lighting systems in the medium and high bay
areas such as the water treatment plant, maintenance shops, school, etc., with T5 fluorescent fixtures.
HID lighting is often used in areas with high ceilings or roof structures. The fixtures generate high
luminous flux, are reasonably energy efficient, and are long lasting. Such systems often remain
illuminated continuously since the re-strike times make periodic switching in irregularly occupied spaces
a nuisance. Continuous operation of HID fixtures reduces the overall energy efficiency of lighting
systems designed around their use. Newer, high output fluorescent sources, characterized by quick warm-
up, with instant light output and improved efficiency, are now being used in place of many medium
wattage HID fixtures in low and high bay applications. Post-light levels will be nearly equal to that of the
existing lighting systems
44..11..22 MMeecchhaanniiccaall OOppppoorrttuunniittiieess
M01 – Boiler Tune-Up
This ECO proposes a comprehensive re-commissioning of the boilers in each building to optimize system
operations. Such efforts include:
Replace, repair, calibrate or install sensors or switches
Repair air linkages
Conduct combustion efficiency test services
Clean combustion chambers and stacks
M02 – Furnace Upgrade
This ECO proposes replacing existing fuel oil furnaces with more energy efficient units. Many of the
existing units in the village are original to the buildings they serve and have reached the end of their
useful service life. Furnaces employing modern technology can be installed to reduce energy
consumption, improve system operations, and reduce maintenance costs.

Due to the brief nature of these contracts and the high cost of travel to and from the villages, audits were
conducted a quickly and efficiently as possible. Once engineers or subcontractors have left the villages,
communication is strained at best, and gathering additional information is difficult. Because of this,
assumptions must be made during the initial ECO assessments and project cost estimates. Occasionally,
Ameresco engineers have found that previously identified projects have been externally funded from
another source, but this information usually comes too late in the process. As a result of all these factors,
some previously identified projects have been modified or abandoned. Final project costs and expected
annual savings can be found in Appendix A. ECOs that were categorized as “Not Funded,” whether in the
initial stages of the proposal or during construction, can be found in Appendix B.
