Abstract
With the latest published version LEED (v4), and the IES codifying two recommended annual-climate-based daylighting metrics and performance criteria, annual daylighting simulation has become even more important to the design professions than ever before. However, interpretation and application of annual-climate-based daylighting data are still relatively novel. Moreover, there remains a lack of consensus regarding the proper behavioral patterns that annual-climate-based daylighting simulation should employ regarding operation of interior manually-controlled window blinds. This study documents a 8-year human factors daylighting field research project using students’ daylit area drawings and qualitative assessments of daylight sufficiency and corresponding point-in-time and annual-climate-based daylighting simulation in a variety of building types (n=24) in order to provide insight to the building performance simulation community about application of these new annual daylighting metrics.
