Does the institution use motion, infrared, and/or light sensors to reduce energy use for lighting in at least one building?:
Yes
None
A brief description of the technology used:
The lighting systems in many campus buildings are automatically controlled by electronic occupancy sensors. Depending on the area and the function of the space, some occupancy sensors are based on ultrasonic technology to detect “movement” or infrared technology to detect “heat.” The lighting in some spaces is controlled by occupancy sensors that have both types of technology present to detect movement and heat. The occupancy sensors are generally used to turn lights off during unoccupied periods. However, in some buildings, occupancy sensors are used to control the brightness of the light fixtures. During occupied periods, the lights are at full brightness. During unoccupied periods, the lights are automatically dimmed to a pre-programmed level.
