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?

Hi In our project we are trying to achieve this credit via the option of a vegetated roof. However, the depth of the growing medium will be less than 6 inches. Did we still can can obtain credit SS 5.1 and 7.2, if our green roof will be extensive with six or more varieties of sedums or other plants? Thanks for any advice.

The LEED Reference Guide defines vegetated roofs as "a layered system that consists of vegetation, growing medium, filter fabric, drainage, and a waterproofing membrane atop a conventional roof." LEED does not differentiate between extensive and intensive vegetated roof systems for the purposes of this credit.
