“Appurtenances” such as these are excluded from the credit. To quote from LEED Interpretation #10235 made on 10/01/2012, “Roof area that consists of functional, usable spaces—such as helipads, recreation courts, and areas covered by equipment, solar panels, and appurtenances—can be exempted from the roof calculations for SSc7.2. Projects are not eligible for SSc7.2 if the exempted spaces encompass the entire roof area.”
