I have two questions regarding heat island reduction credit:

1. I would like to confirm if in LEEDv4 roof area under ventilation ducts and pipes should be excluded from the calculations just like area with mechanical equipment fixed to the roof surface. In our case the roof area under the ducts and pipes will be covered with a high reflective material complying with SRI requirement.

2. There is a terrace on the roof with tables and chairs. A part of this terrace has a glass overhang. How should we treat the roof terrace under the glass overhang and the overhang itself?
