As sunlight scatters through the atmosphere, it turns the entire sky dome into a daylight source. The proper use of daylight coupled with thoughtful electric lighting design and control applications can significantly reduce energy used by lighting.
ALG Online (Advanced Lighting Guidelines) devotes an entire chapter to understanding the impacts of daylight on commercial spaces and effective ways to integrate daylighting strategies into low-energy building designs.
