A project with a 30,000 sq. ft. building footprint has been designed with a 100% green roof. Renewable energy certificates will provide 25% of the electricity. The project team is revising the design to decrease the size of the green roof by 5,000 sq. ft. and add 5,000 sq. ft. of photovoltaic cells to the roof. What credits/prerequisites will this design change not affect?
A: Sustainable Sites Credit, Site Selection, On-site Renewable Energy
B: Energy and Atmosphere Prerequisite, Fundamental Commissioning of Building Energy Systems
C: Sustainable Sites Credit, Site Selection, Heat Island Effect-Roof
D: Sustainable Sites Credit, Site Selection, Stormwater Design-Quantity Control

参考答案: C

本题解释:
Adding photovoltaic cells will contribute to On-Site Renewable Energy.

Renewable energy systems (wind, solar, etc.) are part of the commissioning process for Energy and Atmosphere Prerequisite, Fundamental Commissioning of Building Energy Systems.

Decreasing the size of the green roof will alter stormwater quantity, thereby impacting Stormwater Design-Quantity Control.

The green roof calculation excludes areas with solar energy panels. So even though the original green roof would have been 30,000SF, taking up 5,000SF of space for solar panels will not affect the PERCENTAGE of green roof. A 30,000SF roof with 5,000SF of solar panels and 25,000SF green roof will still be considered to have 100% green roof, so this will not have an effect on Sustainable Sites Credit, Site Selection, Heat Island Effect-Roof.
