A century ago, everyone could look up and see a spectacular starry night sky. Now, millions of people across the planet will never experience the majestic night sky where they live. The widespread use of artificial light at night is not only impairing our view of the universe, it negatively affects our environment, our safety, our energy consumption, and our health. Light pollution creates an abundance of environmental problems. Wildlife species that hunt or forage at night may be unable to feed. Humans overexposure to artificial lighting, particularly at night, may disrupt our circadian rhythms and melatonin production, impair night vision, and lead to sleep disorders. In this presentation, we explain how project teams can achieve the LEED v4.1 BD+C and O+M Light Pollution Reduction credit. Our team discusses the B.U.G. rating method and how it can help reduce light pollution.
