A project team will attempt to reduce water use in their tenant space. What strategy would help earn Water Efficiency Credit, Water Use Reduction?
A: Replacing all water closets with units having 1.6 GPF
B: Treating 50% of wastewater onsite to tertiary standards
C: Implementing a Xeriscape and using graywater for any irrigation
D: Installing HETs
E: Installing ENERGY STAR water efficient dishwashers

参考答案: D

本题解释:
High Efficiency Toilets (HETs) would have a significant impact on the quantity of water used.

Replacing all water closets with units having 1.6 GPF would only meet the EPA flow requirements. To meet the credit a 20% reduction is needed after the EPA baseline for fixtures has been met.

Any irrigation calculations do not apply to Water Efficiency Credit, Water Use Reduction.

Wastewater applies to Sustainable Sites Credit, Site Selection, Innovative Wastewater Technologies. Also, 100% of wastewater must be treated to tertiary standards to meet Sustainable Sites Credit, Site Selection, Innovative Wastewater Technologies.

Water efficient dishwashers can be included in exemplary performance for Water Efficiency Credit, Water Use Reduction, but not for the credit itself.
