Biological systems have adapted over billions of years to the cycles of day and night. Electric lighting (Artifical Light at Night or ALAN) has disrupted these delicate balances, creating an epidemic of light pollution and squelching the darkness. In this course, we explore the the impact of site lighting on the night sky and ways to design exterior and site lighting that minimize this impact. Through high-level discourse, practical considerations and design strategies, and a review of the LEED and SITES light pollution credits, this course will provide building industry professionals with a grounding in sensitive approaches to electric lighting in the outdoor nighttime. This course can be held virtually or in-person.
