Full Description

Daylighting refers to the art and practice of admitting beam sunlight, diffuse sky light, and reflected light from exterior surfaces into a building to contribute to lighting requirements and energy savings through the use of electric lighting controls. The role of electric lighting in daylighted spaces should be to complement daylight during daytime and supply the required illumination levels during nighttime.
