If you have ever worked on a project seeking LEED certification or have studied for the LEED exam, then you will recognize this term from the Sustainable Sites section as one of the point options covers “Light Pollution Reduction.” The idea is that excessive artificial light – whether it’s a low glow or bright glare – spilling into the atmosphere or onto other properties negatively affects nocturnal environments and obscures the night sky for everyone, including astronomical observatories. The International Dark-Sky Association (IDA) and other groups have been on the forefront of the “dark-sky movement,” which only continues to pick up followers.
