I have a question about meeting exemplary performance for credit SS 7.2. The reference guide states that, " Projects may earn an Innovation in Design credit for exemplary performance by demonstrating that 100% of the project's roof area (excluding any mechanical equipment, photovoltaic panels, and skylights) consists of a vegetated roof system." If mechanical equipment is in a penthouse and the penthouse has a roof on it, does the roof of the penthouse count as "roof" and therefore need a green roof system on it. The penthouse roof would only be accessible by ship's ladder. Similar to the previous comment - roof pavers would be part of the green roof system, in order to allow access to the roof for maintenance, etc.
