Does the institution use Light Emitting Diode (LED) technology in at least one lighting application? LED applications in exit signs and remote controls do not count for this credit.:
A brief description of the technology used:
UAF has made many lighting improvements over the years. Energy used for lighting comprises nearly 30% of our power plant's output. As a result, lighting has been a focus of many conversion efforts at UAF spanning more than 20 years.
One of our most successful conservation efforts, which began in 1994, has been a system-wide conversion to a new, more efficient fluorescent lamp called the T-8. The T-8's use 1/3 less energy and last 2 1/4 years longer than its predecessor. This change has significantly reduced our electric bill and maintenance costs. We have also been testing and researching LED technologies and potential uses.
In the late 1990's, the campus emergency phone's lights were converted to LEDs. The long life of the LEDs increased safety and reduced maintenance labor costs.
Upper dorm (Moore, Bartlett, Skarland): January - LEDs tested and successful. Incandescents were short lived. April - Relamped soffit around the complex. Sixty incandescent lamps replaced with LEDs. Payback on electrical usage less than two years, labor savings, and students have reliable illumination along pathways.
Kuskokwim Campus facility upgrade: LED exterior lighting installed.
Harper Building: LEDs installed for new signage.
Lola Tilly East entrance: Yellow sodium vapor fixtures under walkway canopy replaced with LED fixtures. Previous illumination was inadequate. New LED provided better illumination and enhanced aesthetics.
North bike path, between North Tanana Drive to Farmers Loop: High Intensity Discharge (HID) fixtures replaced with LED fixtures.
Barnette Street Parking garage: UAF parking services evaluating cost benefits of conversion to Induction lighting from existing and failing HID fixtures.
Intersection of Tanana Loop West and Yukon Drive: Test street light pole has been installed. LED fixture installed in January.
