Alaska Building Science Network – Village End Use Energy Efficiency Program – ’05-‘06 Final Report – NW/SW Regions – Buckland 9 High Output T5 Lighting Upgrades for the Buckland Gym Existing 400 watt Multi-vapor lighting in the Buckland Gym Estimated Annual Savings: Hours Per Day / 250 Days Per Year Electrical Savings Avoided Diesel Use Avoided Diesel Costs 4 Hours $2,783 453 Gallons $1,105 7 Hours $4,871 793 Gallons $1,934 10 Hours $6,958 1,132 Gallons $2,763 Notes: It’s always good news when we find a gym that has 400 watt multi-vapor bulbs for existing lighting. T5 lighting can produce huge savings and better quality light over these existing systems. The Buckland school gym existing lighting is also supplemented by 8’ fluorescent light fixtures. When the new T5 fixtures are installed during the summer recess of ’07, the new energy use will be reduced by 54% overall. Switching options will provide opportunity to achieve even more savings by choosing to power partial lighting. The following page details this lighting upgrade that will be installed entirely by in-kind labor provided by the Northwest Arctic Borough School district. 10 Buckland School, T5 Lighting Upgrade Details - ABSN Energy Efficiency Projects '05-'06 These retrofits will be completed in June, 2007, per Northwest Arctic Borough School District Maintenance.

Following the course, Charlie spent another full day working with the maintenance staff on heating system energy efficiency and retrofit activities. During the 16-hour course Charlie instructed the Buckland maintenance staff in the fundamentals of boiler and fuel energy efficiency. This training 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. Additional Heating Energy Efficiency Activities The following is a trip report excerpt by Charlie Deer - detailing his energy efficiency heating training and maintenance activities with Buckland maintenance staff: “I had the class visit the clinic as their maintenance man was one of the students. He had one boiler down and we were able to trouble shoot it to find the problem but he did not have authority to fix anything. It was a good experience for the class. As many of the over engineered, over built buildings being built in rural Alaska, the circulating pump was running 24/7 and the building was over heating. The maintenance man programmed a thermostat for one of the zones in the clinic and will install it as soon as he can get permission from Kotzebue. We replaced two thermostats in the city building with seven day, programmable, ones. There was no more opening the windows to control the heat. The maintenance staff wire brushed the boiler in the community building and tuned up the burner using the FGA Kit provided by AEA. We installed an out side reset to control the boiler temperature and save fuel. Maintenance staff also installed two programmable thermostats in the community building.” 12 Buckland, In-Kind Contribution Tracking Record - ABSN Energy Efficiency Projects: Village entities worked with: Tribe, City, School District.
