FAQs about SSc7.2 :

We don't have enough SRI-compliant roofing to earn the credit, but we have a lot of relatively high-SRI roofing (SRI 70). Is there any way to earn the credit?

We don't know the SRI value of some roofing materials we are using. What should we do?

What do I do about roof area covered by solar panels, skylights, space for occupants, helipads, etc.?

Speaking of appurtenances, there is a rooftop pool. Should that be included? Do I need to figure out the SRI value of water?

Do balconies and terraces need to be counted towards the roof square footage?

How does one calculate the square footage of a pitched roof?

What type of ongoing maintenance of the roof is required?

Does anyone know the typical SRI range for wood (light colored to dark colored)? I know that it differs from one product to another, and that we need the manufacturer's documentation proving the SRI, but I need an estimate range for now, if possible! Many thanks..

George, SRI for natural materials are a little harder to come by because they vary for each sample. The closest thing I have seen is the data in this document- which includes an SRI of roughly 22 for brown painted wood shingles. http://www.fsec.ucf.edu/en/publications/html/FSEC-CR-670-00/ Regards.

Thanks Yetsuh, So I think one should paint his wood white in order to achieve a better SRI, because 22 seems to be somewhat low! Regards..

George, The toolkit now includes SRI studies performed for "Certi-labeled" cedar shingles. The numbers are pretty good, SRI of 61-64. These studies are only applicable to certi-labeled shakes or shingles and I am not certain of their availability but this data should meet the requirements for SSc7.2.
