Recommended Action Install occupancy sensors in the office and production areas at this facility to reduce electrical energy usage. By wiring occupancy sensors into certain areas of the facility, lighting could be eliminated during unoccupied periods.
Energy savings wll result from reduced electrical energy usage by the lighting system.
The recommended occupancy sensors also have a photocell built into them that will keep lights off when natural lighting levels are adequate. There are several types of occupancy sensors available. The infrared wall switch units are installed into the switch plates of current lights. These units turn the lights off and on by detecting differences in the heat given off by a human body and the surroundings. They work best in enclosed offices where the light switch area has a clear view of the entire area.
