"The campus is in the process of retrofitting older T12 fluorescent lighting fixtures by replacing them with more energy-efficient T8 (or T5) fixtures and electronic ballasts. The lighting retrofit proposed in the SAIC report would reduce campus energy consumption by ~1.6 percent; a very small amount of this is due to the use of occupancy sensors and day lighting controls. Extending this retrofit to smaller campus buildings, replacing other lighting fixtures (besides T-12s), and a wide deployment of both occupancy and daylight sensors (which can reduce lighting use by 20 percent to 80 percent depending on location) should be able to provide significantly more energy savings than predicted in the SAIC report. The campus target for lighting is 2 percent."
