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: Energy and Atmosphere Prerequisite, Fundamental Commissioning of Building Energy Systems
B: Energy and Atmosphere Credit, On-Site Renewable Energy
C: Sustainable Sites Credit, Stormwater Design-Quantity Control
D: Sustainable Sites Credit, Heat Island Effect-Roof

参考答案: D

本题解释:
Notes:
Adding photovoltaic cells will contribute to Energy and Atmosphere Credit, 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
Sustainable Sites Credit, 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, Heat Island Effect-Roof.
