LEED (Leadership in Energy and
Environmental Design)
The LEED Green Building Rating System for New Construction (LEED-NC Version 2.0) was first published in 1999. The LEED rating system was developed by the U.S. Green Building Council (USGBC) to promote buildings that are not only environmentally responsible in their design, but sustainable, profitable in their operation and healthy to live and work in.
Building owners and design teams not only receive peer recognition for their green building efforts, LEED buildings may qualify for government incentives.
There are no “LEED Approved” products. A LEED project is rated and subsequently classified through a registration process and ultimately, ranked by a point total based upon compliance with the rating system. The LEED rating system offers third party validation for specific certification levels. Certification levels range from Certified (26-32 points) to Platinum (52-69 points).
Specific to roofing, under the latest Version 2.2; LEED NC, Green Building Rating System for New Construction and Major Renovations projects may receive one (1) point under SS Credit 7.2: Heat Island Effect: Roof, by installing a “cool roof” per the LEED Solar Reflectance Index (SRI) requirement on a minimum of 75% of the building’s roof surface. Alternately, a vegetated green roof may be installed on at least 50% of the roof area or a proportional combination of both SRI compliant roof and vegetated roof.
To be considered compliant with the rating system, an SRI of 78 or greater is required for low slope roofing system (≤2:12). FiberTite® beige and white roofing membranes greatly exceed this requirement.
