To help with water use reduction in LEED a lavatory faucet must use less water than the rates set by:


A: Local code
B: EPAct 1992
C: Clean Water Act
D: WaterSense

参考答案: B

本题解释:
A The rates of local codes are not used to set the baseline rate for water use reduction calculations.
B EPAct 1992 is the standard used to calculate baseline water usage, not the design case. EPAct 1992 mandated the use of water conserving plumbing fixtures in residential, commercial and industrial buildings. The answer choice of \'Installing fixtures that meet the EPAct 1992 standard\' only meets the baseline standard and does not contribute to reducing potable water use for the purposes of earning LEED credits.

The fixture and flow rates of EPAct 1992 are used to set the water use baseline for a building. The design case must reduce water use 20% over the baseline. In order to do this, low flow fixtures must be used in the design, or replacing potable water with graywater/stormwater. Think of the fixtures and flow rates of EPAct 1992 as the worst case scenario.
C The Clean Water Act does not address flush/flow fixtures.
D WaterSense is an EPA certification awarded to fixtures that use less water than comparable fixtures. LEED does not use this certification to for the baseline rate calculations.
