Daylighting Controls

Daylighting systems, which use natural lighting to supplement electric lighting, offer the potential to cut energy use, reduce peak demand, and create a more-desirable indoor environment. Some daylighting systems work well, cutting lighting energy use by 20 to 80 percent and providing an aesthetic work environment. But many systems fail to live up to expectations—often because of shortcomings with daylighting controls. The key to getting more systems to live up to their potential lies in combining good design of the control system with commissioning, effective coordination of the efforts of many building disciplines, and training building occupants on how to use the systems.
