NC-2009 SSc7.2:Heat Island Effect—Roof

When your manufacturer doesnt have SRI values

In regards to this credit the LEED REFERENCE GUIDE FOR BUILDING DESIGN & CONSTRUCTION WITH GLOBAL ALTERNATIVE COMPLIANCE PATHS for LEED 2009 says that "Projects outside the U.S. may meet the material solar reflectance index (SRI) testing requirements by consulting the Cool Roof Rating Council’s (CRRC) Rated Products Directory at http://coolroofs.org/products/results and ANSI/CRRC Standard 1, for a list of materials and associated SRI values. If the project’s specific material is listed, provide the SRI rating from this website as documentation in the credit form to fulfill the testing requirements. Color values do not have direct correlation to emissivity and solar reflectance values which are the basis for the SRI calculation. The project can meet the testing requirement in one of three ways: by conducting in-place testing, finding a local lab for sample testing, or by using previous project data to determine the SRI." Does that mean that ONLY projects outside the U.S. can do in-place testing or local lab testing when the material they want to use doesnt have manufacturer SRI values?

Erin, I think that's how it's written, but it seems reasonable to me to be able to apply this domestically. I would contact GBCI to confirm.
