9 Alaska Building Science Network – Village End Use Energy Efficiency Programs – ’05-06 Final Report – NW/SW Regions - Savoonga 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: Savoonga: Cedric Toolie; Selawik: Daniel, Harry Foxglove; 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 the 4 village 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 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.
