Most of the Native Council and City offices had newer existing magnetic ballasts with low ballast factors and relatively low existing energy use. Two lamp fixtures that normally use 80-somem watts for the magnetic ballast and 2, 40-watt lamps were using 70 watts. The ABSN field manager tailored the retrofit plan to use 32 watt T8s where needed for light levels and 25 watt lamps in corridors and other areas where the light level demand was not as great.

Although the pre-post energy reduction shows only 19%, the savings will be greater as the increased light levels of the new T5s allows a partial number of fixtures to be used for most of the run-time. “The savings are going to be more than the savings based on each light fixture. The lights are brighter so we are turning on less fixtures at Port Heiden.” – Vince Webster, Facilities Manager, Lake and Pen. School District Vince has gone on to purchase more T5s from his district budget and replaced several other Lake and Pen school gyms with energy efficient lighting.

This will save 455 watts over existing lighting to achieve a 19% savings. 2545 Lake & Peninsula School District anticipates greater savings than the 19%. They report brighter lighting with the T5s which allows some T5s to remain off much of the time. -18.94904459 Savings & Payback Calculation for Gym: Assume 1800 hrs / year for 250 days/year of use Full cost of electricity: $0.40 /kWh Watts of existing lighting: 3,140 New wattage for T5 fixtures: 2,545 Calculation: (Watts) x (hrs/year) / (1000w/kw) x (cost of electricity) = (cost / year) Existing Cost: $2,261 Retrofitted Cost: $1,832 Annual Savings: $ $428 Est material & shipping cost of Gym retrofit: $4,230.66 Simple Payback: Materials cost / annual savings = 9.875490196 years (for retrofit to pay for itself in materials) This would be if they used all lights during all run times, which is not the case.
11 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’05-06 Final Report – NW/SW Regions – Port Heiden Energy Efficiency Heating System Retrofit – Lake & Peninsula School District Meshik School New Boilers supplied by Lake & Pen SD New piping loops to separate boiler heating loops Cic pumps provided by ABSN / AEA This heating Retrofit was completed in the summer of '06 through in-kind labor provided by the Lake & Pen. SD. VEUEEM grant funds supplied 2 new Grundfoss circ pumps, several circuit setter flow-reducer valves, new pipe for isolating heating loops and control components. – These materials enabled 6 older circ pumps to be taken off-line saving substantial electrical energy. As this was also part of a larger boiler and control replacement plan, this measure will result in substantial fuel savings as well. Vince Webster, Facilities Manager, Lake and Pen. School District has stated they expect a 25% or more reduction in their overall fuel use for all school facilities. Vince gave a ball park average of fuel use of ~10,000 gallons of fuel per year for the Meshik school. 20%, or 2000 gallons x $3.33/ gallon translates to an average annual fuel savings of $6,660.

Both boilers in Ray’s Place were cleaned and tuned for maximum energy efficiency. Charlie Deer provided training and worked with Andrew Lind to retrofit both boilers with outdoor temp boiler controls. These controls can save 5 – 15% of overall fuel use. Programmable Thermostats for Ray’s Place, Native Council Building Andrew Lind programs Thermostats Demonstrating use of programmable thermostats to office staff Notes: Eight programmable thermostats were installed in Ray’s place including the clinic to reduce overall fuel use.
