Dark Sky Policy Evaluation


The Dark Sky denotes a place where the darkness of the night sky is reasonably free of interference from artificial light to reduce light pollution. Dark Sky lighting is lighting provided where it is needed, while reducing unnecessary scattered light and glare. Dark Sky focuses on only using as much light as is needed and when it is needed.

The advantages of reducing light pollution include an increased number of stars visible at night, reducing the effects of light on the environment, and cutting down on energy usage. Scientific studies have shown that light pollution, the inappropriate or excessive use of artificial light negatively impacts the environment, human health, military nighttime activities, and is wasting energy and financial resources. Thousands of cities across the world have adopted codes as a tool for a community to use to control light pollution, including glare, light trespass and skyglow.
