Since this building is basically housing for itinerant trades people working in Chevak, light levels suitable for offices or clinics are not necessary. Retrofitting nearly exclusively with 25w T8 lamps provided adequate light and great savings.

17 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’05-06 Final Report – West Region - Chevak Six Programmable Thermostats were installed in Chevak Community Buildings Maintenance staff installing and programming new thermostats One programmable thermostat was installed in each location listed below: City Office Building, Traditional Council Office Building, JVP Bingo Hall, Chevak Clinic, Corporation Grocery Store, Corporation Office Building Chevak Company Corp Store – Old Hardware Store and Upstairs Offices Chevak Company Corp Store – Old Hardware Store, Offices and Rental Apartments upstairs Largely unused lower level – former location of only existing thermostat New location of programmable thermostat Notes: The Chevak Company Corp Store Office building has good potential for significant fuel savings resulting from the programmable thermostat installed. There was one existing thermostat for the entire building controlling the forced air furnace from the first floor old hardware store area. Late in 2006, this area was shut down for retail sales. This area was still used occasionally for laundry and the ad joining snow machine shop and warm storage was still used. However, the entire lower level did not have to be kept at more than 50 – 55 degrees. The areas of the building that needed heat were all upstairs in offices and rental apartments. In order for those spaces to be at 65 – 70 degrees, the old thermostat located in the unused space was set at a permanent 70 degrees. All the forced air heat vents in the downstairs area were closed to facilitate heat getting upstairs. But this meant the downstairs could never get to 70 degrees and so heat was constantly called for and the furnace ran nearly perpetually. In the afternoons on sunny days when solar gain helped heat upstairs offices, the furnace would still be running – trying to reach 70 degrees downstairs – resulting in overheating the upstairs and burning unnecessary fuel. Village Corp maintenance staff ran new thermostat wire and installed a programmable thermostat upstairs in the apartments, so heat could be controlled where heat was needed.
