OP-T2-14: Lighting Sensors
Does the institution use motion, infrared, and/or light sensors to reduce energy use for lighting in at least one building?:
A brief description of the technology used:
Ultrasonic occupancy sensor wall switches were installed in 53 bathrooms in 8 buildings on campus as a pilot project. We anticipate that these sensors will reduce bathroom lighting usage by up to 60%.
In Pulliam Gym, the old lighting with metal halide lamps, magnetic ballasts, and spun aluminum reflectors was replaced with new high-bay linear fluorescent fixtures with T5HO lamps. This change has increased light levels by 30%, made the light distribution more uniform, eliminated ballast humming, improved color rendering by 31%, and reduced the total lighting power by 21%. The lights for each basketball court are automatically controlled with passive infrared (PIR) occupancy sensors so that the lights only turn on when the gym is in use, where before the lights remained on all day. We expect that the occupancy sensors will reduce the lamp burn hours between 50% and 75%.
The percentage of building space with lighting sensors:
