Daylighting controls reduce artificial lighting in response to sunlight coming in through windows and skylights. They were first introduced in ASHRAE Standard 90.1-2010 for commercial buildings and are now part of 90.1-2013 and the 2015 IECC. This webinar reviewed the fundamentals of daylighting, described how daylighting controls work and save energy, and reviewed daylighting control requirements in the latest codes and standards. It also discussed how these controls should be implemented and commissioned.
