Audrey Fischer of the Chicago Astronomical Society stops by the Que4 Studio to talk about the Chicago Smart Lighting Project, which is already being tested in seven neighborhoods, as the City replaces some 270,000 streetlight. She is joined by Dr Fabio Falchi, who is co-author of The New World Atlas of Artificial Night Sky Brightness, and is one of the world’s leading experts in the area of dark skies research, and Dr Mario Motta, a past board member of the International Dark-Sky Association (IDA) and the lead person for the American Medial Association declaration on human health and light pollution. They discuss what the City of Chicago needs to do to create a safe, effective lighting system.
