GB8: Efficient Site Lighting

(1-3 points)

Purpose

Promote a safe environment for pedestrian networks and bicycle paths, reduce light pollution and use energy more efficiently when illuminating. Improve efficiency of pedestrian and community roadways and improve amenity lighting.

Criteria

Pedestrian Scaled Cut-Off Fixtures (1 point)

Provide pedestrian-scaled lighting along all pedestrian pathways and in public open space areas. Use International Dark-Sky Association-approved light fixtures or equivalent standard.

AND/OR

Energy Efficient Exterior Lighting (3 points)

Design exterior lighting with at least two of the following three strategies for all new exterior fixtures: 

• PV lighting 
• Automatic controls (solar sensor, timer, or other) 
• Pin-based fluorescents or LEDs

OR

Design and install overhead street lights, parking area lights, pedestrian lights and all other exterior community amenity areas according to IESNA guidelines.

To achieve credit for exterior lighting efficiency the project must develop a design according to the Illuminating Engineering Society (IES) standards for Lighting Zone 2 as detailed in the IES publication RP-33-1999, Lighting for Exterior Environments.
