Welcome to the Daylighting Information Clearinghouse!

Brought to you by the Daylighting Collaborative, this site demystifies the why, how, who, and what of the cool daylighting philosophy.

We have redesigned our site to help you navigate your way to the daylighting information you need.

The Daylighting Collaborative brings together utilities, product manufacturers, state agencies, design and construction professionals, and other organizations dedicated to promoting the human, environmental and economic benefits of the daylighting approach to building design.
