Daylight Metrics Update: New Provisions in LM-83-23 Spatial Daylight Autonomy (sDA) and Annual Sunlight Exposure (ASE)
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 […]
