LEED and Lighting
Many of the credit points in the LEED certification system are directly influenced and impacted by lighting strategies. WESCO’s lighting team and LED Aps can help customers in their LEED pursuits and recommend solutions to maximize LEED points.
Minimum Energy Performance
- Each version requires some minimum level of energy performance as defined by some third party standard such as ASHRAE 90.1 or the EPA Benchmarking Tool.
Optimize Energy Performance
- Each version of LEED also allows for additional credits to be earned by out-performing the standard mentioned above by some specific percentage. Typically, this credit offers the greatest opportunity for a project to earn points. Lighting strategies play a key role in optimizing energy and being awarded maximum points.
Minimum Energy Performance
- Each version requires some minimum level of energy performance as defined by some third party standard such as ASHRAE 90.1 or the EPA Benchmarking Tool.
Light Controls
- All versions of LEED offer credits for providing varying levels of individual control and separate control for individual spaces.
Light Pollution Reduction
- This is 1 of only 2 credits totally dependent on lighting issues. The specific requirements and the number of possible points (0.5 to 1) vary between the various versions of LEED. The main goal is to: reduce light trespass onto neighboring properties, improve nighttime visibility through glare reduction, and reduce sky-glow to increase night sky access and to reduce developmental impact on nocturnal environments.
Mercury Content in Light Bulbs
- The various versions of LEED-EB has both a prerequisite and/or a credit (1 point) for maintaining the mercury content of all mercury-containing light bulbs below a specified number of picograms per lumen hour, on weighted average, for all mercury-containing light bulbs acquired for the existing building and associated grounds.
