Hi everyone,
I’m working on a project registered under LEED 2009 C&S Rating System. I understood that roof surface is a surface that covers usable interior space, defined as a space which is both conditioned and occupied. On my project’s roof, there are some mechanical equipment compartments which are enclosed but not conditioned and not occupied spaces. Does my roof surface final count must include the roof surface of those mechanical equipment compartments or are those exempt from the SSc7.2 credit calculation?
Thank you in advance!

It use to be a bit more like you describe it, depending the space being conditioned. But with the new definition of roof area the roof above your mechanical room will be included in the calculation, since it's enclosed gross square footage of the building. However form my experience these mechanical rooms a lot of time are more like a enclosure to prevent direct exposure to rain. So those walls often times are lovers all around and no actual wall separating inside from outside. I think in this case I would excluded such an area form the calculation. I hope that helps.

I would consider it an area that need to be included, after all is an area that otherwise would be heating up and remember the intent of the credit is to avoid the heat island effect.
The only think I could possibly think that can be exluded from the roof of a mechanical room is insulation since it typically is not a comfort area.
Has anybody had any experience about incluidng mechanical room's roof as part of the SSc7.2 scope?
