The roof of an office building is approximately 100,000 sq. ft. Skylights, solar panels, and mechanical equipment account for 20,000 sq. ft. of the total roof area. What minimum amount of the roof would need to be converted to a green roof to earn exemplary performance Sustainable Sites Credit, Site Selection, Heat Island Reduction: Roof?
A: 60,000 sq. ft.
B: 100,000 sq. ft.
C: 75,000 sq. ft.
D: 80,000 sq. ft.

参考答案: D

本题解释:
The purpose of the question is to understand the exemplary performance requirement, which is a 100% green roof.

Remember that a roof can be considered 100% green despite having equipment and solar panels, etc on the roof because those items are excluded from the calculation.

So the roof is a total of 100,000SF, but when you exclude the 20,000SF of skylights, solar panels, and mechanical equipment the remainder is 80,000SF

So a 80,000SF green roof will be considered a 100% green roof.
