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?

Roof slopes in the US are typically referred to as "_ in 12" -- 2:12, 3:12, etc. It refers to the number of inches of rise per foot (12 inches in a foot). The metric system is much more logical.
