It’s easier to see and do work” ~ Bernie Joe – City of Saint Michael 3 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’08-’10 Final Report NW/SW Region – Saint Michael St. Michael City Office Building Above, the converted Anthony A. Andrews school building now houses the St. Michael city government. Center, workers retrofit the city clerk’s office with new T-8 fluorescents. At right, the kitchen boasts its new quick-on, high efficiency lighting system Materials Installed Quantity 2-lamp electronic ballast, (1) 25 watt T8 lamp 4 2-lamp electronic ballast, (2) 25 watt T8 lamps 98 2-lamp electronic ballast, (2) 32 watt T8 lamps 62 CFL-23 W 4 • Pre-retrofit energy use: 13692 watts • Post-retrofit energy use: 8424 watts • Energy savings projection: 5268 watts • Pre-retrofit to post retrofit energy reduction: 38% • Estimated annual savings: Comparative Comparative Hours Per Day / Electrical Avoided Diesel Avoided Diesel 250 Days Per Year Savings Use (gal) Costs 4 Hours/day $3,330.96 356.67 $1,555.08 7 Hours/day $5,829.17 624.17 $2,721.38 10 Hours/day $8,327.39 891.67 $3,887.69 2000 Hours/year (Est.) $6,661.91 713.34 $3,110.15 Notes: Several fixtures were taken off-line in the city office building and the city gym. The new lighting systems were so much brighter than the systems they replaced that 22 fixtures (out of 64) could be taken offline with bet ter overall lighting. In some cases, the new lighting systems would have caused an over lighting situation. The city clerk office was de-lamped on one side to 4 single-lamp fixtures with 25w lamps and 8, 2-lamp fixtures with 25w lamps. Above (L), before and after (center) pictures of the lighting systems in the St. Michael city gym. This facility was recently transferred from the Bering Straights School District to the City of Saint Michael and will be used extensively for community events and activities. The newer lights were so much brighter than the old yellowed lights that the space took on a new feel. At right, lighting in a new classroom/ office space brightened colors and eliminated an annoying buzz 4 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’08-’10 Final Report NW/SW Region – Saint Michael Bingo Hall, Old City Office Above, the old city office, later converted to the St. Michael Bingo Hall, receives lighting upgrades. This building also ho uses the police department and jail, which were retrofitted with compact fluorescent lamps. The building needs a boiler tune-up/upgrade, air-sealing and attic insulation; the building is so drafty nobody noticed when the attic hatch was left open (right).

We also de- lamped the over-lit washeteria next door. Field managers used light meters to verify adequate light levels. Additional Energy Efficiency Measures: ABSN field manager consulted with water plant technicians about the schedule needed for the 2 MBtu backup boiler that heats the recirculation lines that keep the city water system from freezing. It was also determined that during the spring, summer, and fall, the back-up boiler was not needed and was shut off - contributing to substantial fuel savings by eliminating these stand -by heat loses. Freezing problems persist however with the city’s water supply, because oil must be brought manually to the pump shack, and occasionally the oil tank goes dry. 6 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’08-’10 Final Report NW/SW Region – Saint Michael St. Michael Old Clinic Materials Installed Quantity 2-lamp electronic ballast, (1) 25 watt T8 lamp 4 2-lamp electronic ballast, (2) 25 watt T8 lamps 13 3-lamp electronic ballast, (3) 25 watt T8 lamps 4 CFL-14 W 1 CFL-18W 2 CFL-23 W 1 • Pre-retrofit energy use: 2610 watts • Post-retrofit energy use: 1071 watts • Energy savings projection: 1539 watts • Pre-retrofit to post retrofit energy reduction: 59% • Estimated annual savings: Comparative Comparative Hours Per Day / Electrical Avoided Diesel Avoided Diesel 250 Days Per Year Savings Use (gal) Costs 4 Hours/day $973.11 104.20 $454.30 7 Hours/day $1,702.94 182.35 $795.03 10 Hours/day $2,432.77 260.49 $1,135.75 1560 Hours/year (Est.) $1,518.05 162.55 $708.71 Notes: Setback thermostats would have been a good option for this building because of its tendency to get too warm for comfort, but the heating had bypassed the thermostats so a simple retrofit was not possible. The post- retrofit picture (at right) shows some light fixtures were taken off -line for additional savings. Pre-retrofit, this space had been medical exam rooms, but these were converted to residential lodging, which required reduced light levels. A total of four fixtures were taken offline. 7 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’08-’10 Final Report NW/SW Region – Saint Michael New Clinic Materials Installed Quantity Existing electronic ballast, re-lamped (2) 25 watt T8 lamps 29 2 ft fixture, 2-lamp electronic ballast, (2) 17 watt T8 1 2-lamp electronic ballast, (2) 25 watt T8 lamps 2 • Pre-retrofit energy use: 1944 watts • Post-retrofit energy use: 1458 watts • Energy savings projection: 486 watts • Pre-retrofit to post retrofit energy reduction: 25% • Estimated annual savings: Comparative Comparative Hours Per Day / Electrical Avoided Diesel Avoided Diesel 250 Days Per Year Savings Use (gal) Costs 4 Hours/day $307.30 32.90 $143.46 7 Hours/day $537.77 57.58 $251.06 10 Hours/day $768.24 82.26 $358.66 2000 Hours/year (Est.) $614.60 65.81 $286.93 Note: Though the new clinic lighting was fairly recent, newer lamps alone were still able to provide a good energy savings here.
