This document summarizes a presentation on daylighting in buildings and its effects on human circadian rhythms and health. It discusses various daylighting design tools and technologies, including anidolic daylighting systems that can provide significant increases in daylight provision. Experimental findings show that daylight exposure in an office with anidolic systems can provide higher circadian efficacy than artificial light, due to daylight's spectral composition and dynamics. Optimizing light quality and exposure for circadian functions may require considering aspects of building science, physiology, and individual human factors. Further research is needed to better understand light's short and long-term impacts on human health and performance.
