8 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’05-06 Final Report NW/SW Regions - Koyuk Heating Measures for City of Koyuk Office Building: In addition to the lighting upgrades, two Monitor heaters were installed in the City Office Building. The building originally had two large forced-air oil fired furnaces, with one heating the office portion of the building and the other heating the community space. The furnace used to heat the offices was replaced with several Monitor heaters several years ago. The other furnace was still operating, but in need of major repairs. Significant duct leakage into the furnace room made the room unbearably hot. Ducts were run in the cold attic and in a number of places exposed and un-insulated. Duct leakage into the attic space was also occurring. Delivered air temperatures to the far register was 20 degrees cooler than the air directly out of the furnace, indicating significant losses occurring in the attic. Fuel savings is estimated to be a minimum of 400 gallons per year resulting in an annual savings of $1600 per year. Eliminating the large furnace blower should result in several hundred kWh/year savings as well. Simple payback is estimated at 3-4 years. New Monitor Heater Leaky Ductwork in Attic Village Energy Summit: During the final site inspection the Field Inspector arranged a community wide energy summit. To encourage participation, a flyer was mailed to each homeowner offering $1000 worth of energy saving products for each attendee. Contributions from AVEC utility and the Norton Sound Economic Development Corp, as well as funds from the AEA contract allowed us to distribute one Costco pack of 8 cfls, one storm window kit, and one box of weather stripping to each attendee. The training itself was covered by ABSN as an in-kind donation and addition to the VEUEEM project. The meeting was well attended with over 40 homeowners attending which equated to about 50% of the homeowners in the village. Lighting and other low cost energy saving measures were discussed. Each cfl at $.25.kWh and 10,000 hour life would save $250 EACH. The $12 pack of eight cfls would save $2000 in electric costs at the subsidized PCE rate. If only half of the cfl’s were installed and operated for just 3 hours per day, the payback would be still be less than 3 months. Approximately 320 cfl’s were handed out.
