ALAN session at AIA

The Zoological Lighting Institute will host a session on Artificial Light at Night (ALAN) at the American Institute of Architecture’s (AIA) annual convention in New York in June. There will be several topics discussed to place the issue of biodiversity-loss mitigation to the center of architectural sustainability, including bird collisions. This is a great step forward in transforming priorities in architectural sustainability.
