Daylight harvesting utilizes natural daylight to reduce energy usage from electric lighting. It delivers daylight into buildings through windows, skylights, or light shelves and controls it using methods like occupancy sensors, photosensors, or dimming systems. Daylight harvesting systems interact with electric lighting by dimming or turning off lights when sufficient daylight is available and turning lights on or brightening them when daylight levels decrease.
