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 what 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. Another advantage appreciated by building owners is the instant-on function of T5 lighting compared with long waiting periods for older HID fixtures to come on. With the waiting period eliminated, building owners have indicated they are more likely to keep lighting off until needed. 19 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’08-’10 Final Report NW/SW Region - Unalakleet Unalakleet - Alaska Building Science Network - T5 Lighting Upgrade Details These retrofits were completed in (April, 2010).

These are primarily for cumulative, otherwise unaccounted time expense for village- based project support. Feb, '07 through $ 4,322 Each time we call, email, or fax a village entity, someone has to receive the communication, review and/or forward the information, follow-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, 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.

Wage estimate of $30/hr is likely low as Leland did a lot of this work at higher rates & the fringe match from the SD would add another at least 25% to the straight wage. School T5s and dimmable ballasts in lunch room 75 $ 35 $ 2,625 wage is likely low for Leland.

This allowed ABSN and the community of Unalakleet to deliver 44% more energy savings measures beyond original grant funds.
