IES Lighting Measurements (LM) 83-23, Approved Method: IES Spatial Daylight Autonomy (sDA) and Annual Sunlight Exposure (ASE) recently underwent significant revisions and ANSI certification. LM-83-23 describes the IES approved method for computing annualized climate-based metrics for daylight sufficiency (sDA) and for excessive sunlight exposure in buildings (ASE). It provides a common reference standard for daylighting […]

Join us for a panel focusing on some of the research being done to improve safety on the road and in the field.  The projects being showcased include adaptive roadway lighting, updates to the FHWA report on mid-block cross-walks, and an assessment of LED exit signs.    

The authors of three papers recently published in Leukos will present their work on various aspects of daylight and daylighting.  The projects being showcased include: Sunlight Autonomy for Buildings: A New Methodology for Evaluating Sunlight Performance in Urban and Architectural Design, Heliotropic Shading: Daylighting a Rare Books Reading Room with Electrochromic Glass and Parametric Analysis, and Trees in Daylight […]
