Each month, the IES presents a live webinar on a current topic that helps expand your lighting knowledge and furthers our mission of improving life through quality of light. Live and on-demand webinars are free to all IES members, and are eligible for IES continuing education credits (CEUs). Live webinars are available at a fee of $20 for non-members.
Please note, on-demand webinars are available on a complimentary basis only to IES members and are eligible for CEUs for a nominal fee. Non-members may also purchase access to on-demand webinars and corresponding CEUs. Visit our eLearning Portal for additional information on pricing and availability.
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 performance across building typologies and climate regions. Learn from Daylighting Metrics Committee members about important changes made in the 2023 version and their rationale, along with their implications for daylighting design and analysis. Perspectives and discussion regarding the application of LM-83-23 and an outlook toward the adoption of updated methods in software tools will be included.
Reserve a timeslot for a live presentation for the IES Educational Web Series.
