Expresses the support of the House of Representatives for improved night preservation practices in the State of Illinois and encourages municipalities and State agencies (specifically the Illinois Sustainable Technology Center) to research and adopt suitable outdoor lighting practices.
Lighting ordinances are an important tool for setting reasonable limits on light pollution. IDA encourages cities to adopt and enforce ordinances that call for shielded, downward-pointing lighting, curfews and other sensible controls. Doing so conserves energy and helps to minimize glare, light trespass and skyglow.
The International Dark Sky Association and the Illuminating Engineering Society of North America have developed a Model Lighting Ordinance to address the need for strong, consistent outdoor lighting regulation in North America.
The purpose of the Night Sky Protection Act is to regulate outdoor night lighting fixtures to preserve and enhance the state's dark sky while promoting safety, conserving energy and preserving the environment for astronomy.
It is the intent of this Code to define practical and effective measures by which the obtrusive aspects of outdoor light usage can be reduced, while preserving safety, security, and the nighttime use and enjoyment of property. These measures are intended to curtail the degradation of the nighttime visual environment, reduce light trespass, glare, energy and resource waste by encouraging lighting practices that direct appropriate amounts of light where and when it is needed, increasing the use of energy-efficient sources, and decreasing the use of poorly shielded or inappropriately directed lighting fixtures.
