An office space has a baseline water use of 400,000 gallons. What must the design case water use be for the project to earn exemplary performance for Water Efficiency Credit, Water Use Reduction?
A: 180,000 gallons
B: 220,000 gallons
C: 240,000 gallons
D: 160,000 gallons

参考答案: B

本题解释:
See Water Efficiency Credit, Water Use Reduction, Exemplary Performance

For Water Efficiency Credit, Water Use Reduction:

A 30% reduction earns 6 points.
A 35% reduction earns 8 points.
A 40% reduction earns 11 points.

A 45% reduction earns exemplary performance for a total of 12 points.

The question asks for the amount of water use after the design.

400,000 - 180,000 (45% reduction) = 220,000 (new water usage level)

180,000 is not the correct answer. 180,000 is the amount of water that would need to be saved to earn Exemplary Performance, not the amount that will be used in the design.
