Best Strategies to Reduce Light Pollution

Expert Content


Light pollution is caused by the improper use of artificial light from nighttime electric lights, which scatter in all directions away from their source. It is primarily caused by the inappropriate or excessive use of these lights, and it has a negative impact on both animal and human life. The LEED v4 O&M rating system provides an easy-to-implement two optional light pollution reduction plan for projects to use, and rewards compliant projects with a maximum of one point through their certification process. There are also additional strategies that projects can employ, such as using LED lighting or motion sensors on outdoor lighting, to reduce light reduction levels even further.
