Occupancy Sensors.

Occupancy sensors secure power to the lights in unoccupied spaces to conserve energy. This TechData Sheet presents occupancy sensor types, applications, and the potential economic savings of retrofit projects. Manufacturers of occupancy sensors claim energy savings of 5 to 75 percent. Actual savings will vary greatly depending on the amount of light being controlled and the occupancy pattern in the room. Spaces that show the greatest energy conservation from occupancy sensors are restrooms, lunch or break rooms, conference rooms, coffee messes, and copy rooms.
