CS-2009 SSc7.2: Heat Island Effect—Roof
Hello,
The project I am working on consists of a tower with subterranean spaces that lie beyond the tower's footprint. Could we consider the vegetated area over the subterranean as "roof" and include it in the calculations for SSc7.2? Thoughts?
Thanks!

We don't know the SRI value of some roofing materials we are using. What should we do?
Do balconies and terraces need to be counted towards the roof square footage?
How does one calculate the square footage of a pitched roof?

Patrick, I would say that depends in part on the function of the underground spaces. Are they conditioned and occupied?

Hi guys.
We have it the same, but on the contrarary. My guess is that if the underground floors serve as a garage, then the "roof" at the ground level can be considered a terrain instead of a roof and we do not have to count that towards achieving SSc7.2. Any comments on this?

Yet I forgot to mention that besides the green "roof" aka vegetated surface above garage there is a portion of asphalt drive way. That is why we want to exclude it.

Yes they are, both conditioned and occupied.

Patrick, in that case I would consider it a roof.
