Most schools had already switched to 34-watt T12s as an energy saving measure within the last several years. By retrofitting with 25-watt T8s and replacing 72 incandescent light bulbs with compact fluorescents, this school achieved a substantial overall energy cost reduction exceeding 50%. In-kind Labor: Southwest Region School District generously provided all maintenance staff labor in -kind to the grant to complete school facility, teacher housing and Gym T5 lighting retrofits - resulting in substantial direct cost savings to the grant. 9 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’08-’10 Final Report NW/SW Region - Levelock School Materials Installed Quantity 2 ft fixture, 2-lamp electronic ballast, (2) 17 watt T8 1 2-lamp electronic ballast, (1) 25 watt T8 lamp 5 2-lamp electronic ballast, (2) 25 watt T8 lamps 55 2-lamp electronic ballast, (2) 32 watt T8 lamps 6 4-lamp electronic ballast, (4) 25 watt T8 lamps 49 CFL-20 W 1 CFL-23 W 2 CFL-27 W 24 • Pre-retrofit energy use: 16228 watts • Post-retrofit energy use: 8176 watts • Energy savings projection: 8052 watts • Pre-retrofit to post retrofit energy reduction: 50% • Estimated annual savings: Comparative Comparative Hours Per Day / Electrical Avoided Diesel Avoided Diesel 250 Days Per Year Savings Use (gal) Costs 4 Hours/day $5,638.50 743.77 $5,533.63 7 Hours/day $9,867.38 1301.59 $9,683.85 10 Hours/day $14,096.2 1859.42 $13,834.0 1800 Hours/year (Est.) $10,149.3 1338.78 $9,960.53 4-Plex Teacher Housing Materials Installed Quantity 2-lamp electronic ballast, (2) 25 watt T8 lamps 16 CFL-20 W 1 CFL-23 W 39 CFL-27 W 5 • Pre-retrofit energy use: 5333 watts • Post-retrofit energy use: 1788 watts • Energy savings projection: 3545 watts • Pre-retrofit to post retrofit energy reduction: 66% • Estimated annual savings: Comparative Comparative Hours Per Day / Electrical Avoided Diesel Avoided Diesel 250 Days Per Year Savings Use (gal) Costs 4 Hours/day $2,481.50 327.33 $2,435.35 7 Hours/day $4,342.63 572.83 $4,261.86 10 Hours/day $6,203.75 818.33 $6,088.37 1375 Hours/year (Est.) $3,412.06 450.08 $3,348.60 10 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’08-’10 Final Report NW/SW Region - Levelock School Gym Materials Installed Quantity T5 fixture, electronic ballast, (2) 54 watt T5 HO 16 • Pre-retrofit energy use: 2960 watts • Post-retrofit energy use: 1824 watts • Energy savings projection: 1136 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 $795.20 104.89 $780.41 7 Hours/day $1,391.60 183.56 $1,365.72 10 Hours/day $1,988.00 262.23 $1,951.02 1750 Hours/year (Est.) $1,391.60 183.56 $1,365.72 ABSN T5 Lighting plans are designed to increase the average light levels throughout the area when all fixtures are switched on - in comparison with former existing light output. Existing switching controls are normally retained - allowing users to choose the appropriate number of light fixtures / rows of light fixtures needed for various use patterns. In many cases school staff will choose not to use all fixtures available, thereby achieving more electrical savings than is shown above. Considering light quality, ABSN T5 lighting plans employ 54-watt, high output T5 lamps with a color-rendering index (CRI) of 85. Existing light fixtures in rural high ceiling areas typically have a CRI ranging from 30 to 70. With the T5 retrofits, the boost in CRI greatly improves light quality – resulting in objects appearing much closer to their true color as seen under sunlight. This increased light quality can result in less light needed to illuminate a given space - for example fewer rows of fixtures selected to light the space. 11 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’08-’10 Final Report NW/SW Region - Levelock Levelock - Alaska Building Science Network - T5 Lighting Upgrade Details These retrofits were completed in October, 2009 Levelock Gym Length (feet) Width (feet) Ceiling Height (feet) Type of Existing Fixture # of Existing Fixtures Existing Fixture Wattage Total Existing Wattage Existing Foot- candles New Foot- Candles # of New Fixtures New fixtures New Fixture Wattage Total New Wattage 80 50 20 HPS 150 watt 160 0 22 32 16 T-5 2 lamps 114 1824 Color shade of walls HPS 250 watt 260 0 T-5 3 lamps 171 0 Color shade of floor Multi- Vapor 400 watt 415 0 T-5 4 lamps 228 0 HPS 175 watt 16 185 2,960 T-5 6 lamps 342 0 Total Existing Watts 2,960 Total New Watts 1824 neg 1 (New watts / Old watts x 100 - 100) / 100 Percent Savings Pre to Post Retrofit: 38.38% Savings & Payback Calculation for Gym: 1750 New watts / old watts Assume 1750 hrs / year for 250 days/year of use Full cost of electricity: $ 0.7000 /kWh Watts of existing lighting: 2,960 New wattage for T5 fixtures: 1,824 Calculation: (Watts) x (hrs/year) / (1000w/kw) x (cost of electricity) = (cost / year) Existing Cost: $ 3,626 Retrofitted Cost: $ 2,234 T5 Materials cost, PO 212: $ 2,806.96 Annual Savings: $ $ 1,392 Shipping cost: $ 171.25 U.S.P.S.

Total project cost = $33,700/village - (our admin percentage , (around 12%) Approx: $4,044) = $29,656 x 5.5% = $1,631 (this 5.5% village admin cost estimate is spread across all entities we work with for the course of the grant for completing all energy efficiency measures. These are primarily for cumulative, otherwise unaccounted time expense for village- based project support. Feb, '07 through $1,631.00 Each time we call, email, or fax a village entity, someone receives the communication, reviews and/or forwards the information, follows-up on requests, etc. Whether it is to set-up a teleconference, verify maintenance staff participation in lighting or boiler trainings, set-up in-kind lodging and transportation, lighting trainings, track a shipment, verify completion of lighting in a given building, ship lamps and ballasts out of the village for recycling, request a labor reimbursement agreement, or invoice etc. Village expenses for phone charges, copying and fax costs, office supplies, etc. are part of this amount. Lodging for ABSN Field Managers - 1st assessment site visit Jan-10 3 $150 $ 450.00 $150 Per Night - School Contribution Lodging for ABSN Field Managers - 2nd site visit Jan-10 4 $150 $ 600.00 $150 Per Night - Village Council Contribution School In-Kind Labor 100 $20 $2,000.00 Estimated School In-Kind Labor School In-Kind Labor - Gym T5s $3,700.00 Conservative estimate for total labor contributed including travel and fringe costs. TOTAL $8,921.00 The capacity of ABSN’s scope of work was greatly increased by the response of local communities to work in partnership with ABSN and provide in-kind services of project coordination, paid labor for lighting retrofits, transportation and lodging for ABSN field staff, and other valuable contributions. This allowed ABSN and the community of Levelock to deliver 26% more energy savings measures beyond the original grant funding.
