Collecting and using stormwater to replace potable water use in flush fixtures helps with what project areas?
(choose 2)
A: Water use reduction
B: Reducing the development footprint
C: Stormwater management
D: Reducing heat islands

参考答案: AC

本题解释:
The design case water use calculations use the flush and flow rates of all fixtures installed, the estimated occupancy usage. The design case also includes subtracting out any source of nonpotable water - in this case the stormwater.

Collecting stormwater does not impact the development footprint.

Capturing stormwater for use in flush fixtures reduces the quantity of stormwater flowing from the project site.

The quantity of stormwater on a site does not impact heat islands themselves. The use of open grid pavement on hardscapes would help with both stormwater management and reducing the heat island effect, however that information was not provided in the question.
