Advanced Lighting Control System in an Office Building

The project evaluated wireless lighting controls technology at the Contra Costa County Office of Education building. The project area consisted of two private offices, two open offices, and a non-daylight area. The general lighting for the area is provided primarily by 2' x 4' linear fluorescent fixtures recessed into a grid T-bar ceiling. The existing lighting was retrofitted with new electronic dimming ballasts and wireless controls. The project measured the electrical and lighting characteristics for the base case and for the case of each control strategy, including measured aggregate load measurement, work area load measurement, and work area lighting measurement.
