Natural interior daylight offers a multitude of benefits beyond energy savings. It is the highest quality light source available for interior environments, it is flicker-free and it provides excellent color rendering and color balance. And natural interior daylight is one of the fastest greenhouse gas reducing paybacks you can buy, because it shrinks both energy bills and re-lamping maintenance costs. The fact is, introducing daylight into buildings provides energy savings, excellent lighting quality and more beautiful interior spaces.

  1. Does natural interior daylighting pay for itself?

    Lighting accounts for roughly one third of electricity used by commercial or educational facilities in the United States. Whereas natural interior daylight requires no energy beyond sunlight. And Natural interior daylight is about 10-times more efficient then rooftop PV cells for lighting a room.
