ABSN T5 Fluorescent Lighting plans are designed to increase light levels throughout the space (when all fixtures are switched on) - in comparison with previous existing light output. Existing switching controls are retained - allowing users to choose the appropriate number of light fixtures/rows of light fixtures needed for various use patterns. In many cases building staff will choose not to use all fixtures available, thereby achieving further electric al savings than what is shown above. ABSN T5 lighting plans employ 54-watt, high output T5 lamps with a color-rendering index (CRI) of 85, which improves light quality. Existing light fixtures in rural high ceiling areas typically have a CRI ranging from 30 to 70. The T5 retrofits boost CRI which greatly improves light quality, resulting in objects appearing much closer to their true color as seen under sunlight. This increased light qu ality can result in less light needed to illuminate a given space. As a n added advantage, building owners also appreciate the “instant-on” function of T5 lighting compared with long wait 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. 9 Alaska Building Science Network – Village End Use Energy Efficiency Program – ’08-’10 Final Report Interior Region – Steven’s Village Stevens Village - Alaska Building Science Network - T5 Lighting Upgrade Details These retrofits were completed in April, 2009.

Conservative village office administrative percentage of total project cost less ABSN Admin %. Total project cost = $34,500/village - (our admin percentage , (around 12%) Approx: $4,200) = $30,300 x 5.5% = $1,666 (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 $1,666.00 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.

This allowed ABSN and the community of Steven’s Village to deliver 31% more energy savings measures beyond the original grant funding.
