FAQs about SSc7.2 :

We’re working on an international project and having a hard time finding a coating with a published value for Solar Reflectance Index. If the coating is white, can we assume that it qualifies?

Are solar panels always excluded from the roof area for the purposes of the credit calculations?

Why does the form calculate my high-albedo roof area, as a value greater than 100% of total roof area?

What needs to be included in the roof maintenance program?

EBOM-2009 SSc7.2:Heat Island Reduction—Roof

Weighted approach / SRI below 78

Our project has a low-slopped roof deck that proposes to comply to this credit via Option 3 - combination of high-SRI material and vegetated roof. If we apply a paint that has an SRI value below 78, say 68 (gray color), will we be able to claim the credit? Can we use the weighted average formula? Thanks.

Mary Ann, this seems to go along with how Option 3 should work. Do you have any concerns about the approach?

Thanks, Tristan. Also found an answer to my inquiry in the "A little wiggle room" section above. I just thought that it is a must that the roofing materials have a solar reflectance index (SRI) equal to or greater than the values for low-slopped roof, i.e. SRI of 78.
