Documentation is streamlined for LEED-certified projects. If the project is certified under LEED-NC or LEED for Schools, show that SSc8: Light Pollution Reduction was earned. If the project is certified under LEED-CS and 75% of the floor area is LEED-CI, show that SSc8: Light Pollution Reduction was earned for both systems.

Option 1 – Prior LEED Certification

Choose the most advantageous of the following three options. When possible, Option 1 is easiest, and Option 2 is generally simpler than Option 3.

Exterior Lighting Systems

Occupancy sensors may be the easiest and most cost-effective way to satisfy interior lighting control requirements in buildings that do not currently have automatic controls for perimeter spaces.

Integration of automated controls into interior lighting systems may require a range of low-to-moderate investment depending on the level of implementation required. However, installation of automatic controls typically gives a favorable payback period of 2–4 years and energy savings of up to 40%–50%.

Include seasonal adjustment of the automatic control schedule to maximize energy savings and reduce light pollution.

Interior lighting that does not have a direct line of sight to the building envelope is exempt from the credit. Three sets of exemption guidelines are detailed in the LEED Reference Guide which explain how to measure the distance and angle of lighting fixtures from windows to determine if any of your fixtures may be excluded.

The architect and construction manager work with the restoration contractor to establish appropriate demolition and restoration activities.

Include details on preparation, protection and any special arrangement required during construction. Reused elements may need protective coverings and sheets from contaminants and construction dust
