NC-2009 SSc7.1:Heat Island Effect—Non-Roof

Deck over parking; do I have this right?

Our project has multiple levels of parking under a large podium plaza. I believe this is what what the Reference Guide (p 112) refers to as a "deck", right? Which means, if I read correctly, that we do not have to provide SRI/shade/green roof compliance, correct? The team has endeavored to use high SRI materials, but there are many different materials types, from green roofs to granite to rubber surface for playgrounds, etc. Also, there are some bits of unoccupied space under the podium (but over other parking) that house mechanical equipment, and there are some stairs. As this is not over conditioned space, I do not have to treat these as roof for SSc7.2, right? Thanks for your thoughts....

Susan, Yes, you are right. The parking is considered to be under a deck and hence, the roof of the podium does not have to comply with the SRI requirements. And according to LEED Interpretation LI 2293, the top deck of the podium is considered non-roof area, unless it covers conditioned spaces. So you can exclude this roof for SSc7.2.
