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.
Ann Arbor streetlight victory
The Kerrytown streetlight upgrades will adopt the version of the globes with the top halves blocked out. Specific globe models were already approved for this project, so the only options for modification were to look at different submodels from the manufacturer. We lucked out that one submodel is this more dark-sky-friendly version with internal “light lids”. Moreover, the design was also tweaked to allow lower wattage to reduce glare and save money. Many thanks to the City of Ann Arbor and Downtown Development Authority for taking the trouble to review and revise!
