Daylight harvesting is an energy management technique that reduces overhead lighting use by:
- Utilizing the ambient (natural & artificial) light present in a space
- Dimming or switching OFF lighting when sufficient ambient light is present or when the space is unoccupied
- Utilizing zones to stagger the dimming and switching of lighting loads depending on their distance from ambient light sources, such as windows and skylights
Benefits of daylight harvesting:
- Save money on electrical
- Automated control of lights
- Health benefits of correct lighting
