Lighting consumes about 25 to 30 percent of the electricity in classroom and office buildings on a typical campus, which is why lighting is a high priority for efficiency upgrades. Energy researcher Dr. Greg Monty at N.C. A&T will measure and verify light-related usage at four UNC system schools: N.C. A&T, Winston-Salem State University, the University of North Carolina School of the Arts and UNC-Charlotte. Over the past 25 years, many campuses have converted from inefficient tubes and incandescent bulbs to compact fluorescent bulbs and LEDs that use a fraction of the electricity and last many times longer. In addition, many buildings have been equipped with timers to turn off the lights during periods of no occupancy. Monty will do pre and post measurements to track kilowatt usage while keeping the same light intensity needed at the schools.
