A daylight harvesting system, also known as daylight harvesting controls or daylight harvesting sensor, is an automated lighting control system that adjusts artificial lighting levels based on the amount of natural daylight available in a space. The system utilizes sensors or photoelectric cells to measure the intensity of daylight and then adjusts the electric lighting to maintain a constant level of brightness.
The primary purpose of implementing a daylight harvesting system is to maximize energy efficiency and reduce electricity consumption. By utilizing natural daylight whenever possible, artificial lighting can be dimmed or turned off in response to sufficient natural light, resulting in significant energy savings. This system is commonly used in commercial buildings, offices, schools, and other spaces with large windows or skylights to optimize the use of sunlight for illumination.
