Lighting consumes 25 to 30 percent of the electricity in classroom and office buildings and is a high priority for efficiency upgrades. Over the past 15 years, all of the overhead lighting on campus has been converted from inefficient T-12 light tubes with magnetic ballasts to smaller diameter T-8 or T-5 light tubes with electronic ballasts. The result is better light, a 20% savings in electrical consumption, and substantially reduced maintenance calls. Ninety percent of building mechanical rooms have been equipped with timers to turn off the lights. Forty percent of common spaces, such as restrooms, break rooms, and conference rooms, contain occupancy sensors. Recent improvements in the cost and efficacy of LEDs have encouraged the University to begin testing a variety of fixture types on campus, both indoor and outdoor. Electric costs at the LED-lit Bell Tower Parking Deck are so much lower than at other decks that Parking Services plans to convert all decks to LED lighting.
Standard, screw-in incandescent lights bulbs have been eliminated in all campus buildings and desk lamps. They were replaced with more than 4,000 compact fluorescent light bulbs that use only one-quarter of the electricity and last many times longer. The next generation of lighting technology, known as LED for light emitting diodes, is currently being tested in multiple locations.
