In our original community planning teleconference fo r these grants, we learned that all the lighting retrofits for village community buildings had already been coordinated and completed by the local tribal environmental office and community at large. The only lighting retrofits that had not been completed through the local tribe were 27 linear fluorescent light fixtures in the school and a few cfls to be installed in the teacher housing building. The lighting summary above reflects savings projections from completing those retrofits. The simple payback at 12.87 years reflects only the savings from these few lighting retrofits and is why it is so much longer a time-frame than any other village covered under these grants. The fuel savings from the community center heat recovery project once it is completed will significantly decrease the long payback time currently listed for this village. Nikolski School Lighting retrofits save energy while improving light levels in classrooms for a better learning environment. The main school building and teacher housing building owned by the Aleutian Region School District received the following: Materials Installed Quantity 2-lamp electronic ballast, (2) 25 watt T8 lamps 14 4-lamp electronic ballast, (4) 25 watt T8 lamps 13 • Pre-retrofit energy use: 2822 watts • Post-retrofit energy use: 1828 watts • Energy savings projection: 994 watts • Pre-retrofit to post retrofit energy reduction: 35% • Estimated annual savings: Comparative Comparative Hours Per Day / Electrical Avoided Diesel Avoided Diesel 250 Days Per Year Savings Use (gal) Costs 2160 Hours/year (Est.) $1,395.58 239.44 $797.34 4 Hours/day $646.10 110.85 $369.14 7 Hours/day $1,130.68 193.99 $645.99 10 Hours/day $1,615.25 277.13 $922.84 3 Alaska Building Science Network – Village End Use Energy Efficiency Program –’07-’08 Final Report NW/SW Region - Nikolski Teacher Housing Compact fluorescent light bulbs are a great strategy for reducing wattage use in teacher housing units.

In 2007 and 2008 we coordinated with Nikolski IRA Council, Aleutian Pribiloff Island Association and TDX Power Co. to reserve VEUEEM funds to help complete this measure. The three entities above collaborated on writing a state renewable energy grant to complete a wind - diesel power generation system to supply power to the village. Included in their grant scope is a heat recove ry system for the community building from the power plant. They were awarded the full grant in March, 2009, and the Alaska State Legislature approve that full funding. Grant funds however were not appropriated by the Legislature as of late March, and therefore ABSN could not complete VEUEEM grant spending for Nikolski. With the grant awarded however ABSN continued coordinating with Nikolski IRA Council APIAI and TDX Power to identify critical material components of the heat recovery system and go as far as we could toward spending VEUEEM funds for community building energy efficiency in Nikolski. TDX Power compiled a materials list and selected Mantech Mechanical as their materials supplier for the primary heat recovery parts. See Mantech Mechanical’s i nvoice to TDX Power attached below.

The slated heat recovery system is directly connected and related to their overall wind -diesel power system design, and therefore must be finalized as a process of logistics, site preparation, final work plans and final ad justments to system design, for all components covered in their $400,000 renewable energy grant. Since these funds were so recently appropriated, this process is currently ongoing. All entities involved are moving forward with the Nikolski power system components this construction season. Community Center built in close proximity with the Umnak Power Plant for heat recovery potential Soon the waste heat exhaust fans will not operate as often As soon as final preparations are completed and the heat recovery portion is scheduled, Nikolski IRA Council will invoice ABSN for the heat recovery materials and the VEUEEM grant expenditures for the village will be completed. Nikolski IRA Council’s cost proposal for the heat recovery system listed in th eir renewable energy grant is $43,580. ABSN has reserved approximately $10,000 to contribute to the project, or roughly 25%. Pre-retrofit fuel use data was not available at the time of writing this report. With the substantial in kind contribution for this measure, payback on the VEUEEM grant portion is expected to be reasonable. We will continue to stay in touch with local and regional entities working in Nikolski on this project. As new information becomes available we will report any findings to AEA in future progress reports. 6 Alaska Building Science Network – Village End Use Energy Efficiency Program –’07-’08 Final Report NW/SW Region - Nikolski Nikolski, In-Kind Contribution Tracking Record - ABSN Energy Efficiency Projects: In-Kind Item Dates Hours Contri -buted Hourly Wage Value / Amount Notes Staff time for project contact, introduction, and review of intro materials (Number of entities x 1 hour each) 4 $15 $60.00 list number of entities Staff time for Attending teleconference (TC/IRA) 3 $15 $45.00 list # of staff and wages if possible ($15/hr is an average wage designated for village entity staff).
