10 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’05-06 Final Report – NW/SW Regions - Selawik Selawik Davis-Raymoth School - Facility-wide heating system retrofit Scheduled for installation Jul y, 2007 Existing Boiler system. All 3 boilers have to maintain temperature at all times Notes: The Selawik School existing boiler system has 3 boilers that are all on the same heating loop and therefore all have to constantly maintain temperature – thus using more fuel than necessary. ABSN utilized ~ $13,000 of VEUEEM grant funds to purchase piping, welding, components, circ pumps and other equipment for the retrofit. The NWABSD will provide all in-kind labor to fabricate and install retrofit components. The re-built boiler system will isolate each boiler with it’s own heating loop and circ pump. Boilers may then operate independently of each other to meet heating loads in different parts of the school, thus allowing some boilers to remain cool. Fuel savings is expected to be substantial – in the range of 25% – 30% annual fuel savings. A similar boiler retrofit was completed by the Northwest Arctic Borough School District for the Buckland School in the summer of 2004. According to NWABSD records, without accounting for annual heating and cooling data, straight annual fuel use declined by 30% during the first year and by 50% during the second year compared with pre-retrofit fuel use, school-wide. The difference between 30% and 50% is likely due to one winter being colder than the other. ABSN will be monitoring the installation process and contact AEA with relevant updates. NWABSD facilities and maintenance department has indicated they keep careful records of fuel use in their facilities. ABSN and NWABSD will stay in contact and appraise AEA of fuel savings when a winter’s season of comparative data is available.
Alaska Building Science Network – Village End Use Energy Efficiency Program – ’05-06 Final Report – NW/SW Regions - Selawik 11 Nome Boiler Training In November, 2005 ABSN partnered with Kawerak Housing Authority based in Nome to provide ABSN’s 16 hour boiler training course to 15 rural maintenance staff. AEA VEUEEM grant funds were used to cover air fair and lodging in Nome for the following maintenance staff from this grant’s villages: Selawik: Daniel, Harry Foxglove; Savoonga: Cedric Toolie; Buckland: Jonny Hadley. Using a flu analyzer to test boiler efficiency Charlie Deer covering Boiler Controls Checking CO2 content of flu gases with Bacharak test kit During this 16-hour course ABSN’s boiler specialist Charlie Deer instructed Old Harbor maintenance staff in the fundamentals of boiler and fuel energy efficiency. This benefit to the grant came through an in-kind contribution of $2,100 overall provided by ABSN . Training topics covered: fuel, proper heating system sizing, testing boiler efficiency with a flu gas analyzer kit, cleaning and tuning boilers for energy efficiency, control options and proper control function, burner and nozzle components and function, outdoor temperature boiler controls, programmable thermostats, etc.
