Day Light Harvesting System
Daylight Harvesting is the term used in sustainable architecture and the building controls and active day lighting industries for a control system that reduces the use of artificial lighting with electric lamps in building interiors when natural daylight is available, in order to reduce energy consumption.
Day lighting is the use of daylight as a primary source of general illumination in a space. Day lighting has become a more important feature of mainstream construction due to the sustainable design movement.
Numerous studies over the last 50 years attest to the importance of daylight in design. Research indicates that daylight can improve user satisfaction/performance and retail sales. These characteristics can take any buildings more valuable and marketable. Day lighting also enables daylight harvesting, an innovative control strategy that can generate 35-60+% energy savings. A daylight harvesting system decreases electric light contribution as the daylight contribution increases.
