CI-2009 WEp1: Water Use Reduction—20% Reduction
Hi All,
I am working on a project which is a dormitory. Each living unit has a bathroom which, along with a toilet and sink, contains a combination shower/bathtub. The tub faucet and showerhead will never run at the same time, and both have a maximum 1.5 gpm flow rate.
How should I document this in the water use reduction calculator? Both fixtures are listed in our plumbing schedules so I don't want to confuse the GBCI reviewer.

Can you explain the 12-second duration for metering faucets?
Can I use a nonpotable water source to contribute to WEp1 compliance?
We are having trouble finding EPAct-compliant fixtures. Is that a problem?
Where can I find a clear meaning of "public" and "private" as relevant to lavatory faucets?
Are shower duration controls an acceptable water-saving strategy?
Can I include process water savings in order to earn an Exemplary Performance point?

LEED does not currently include/consider bathtub usage so the bathtub faucet is not applicable. The logic I've heard is that as bathtubs are typically filled to a specific level/volume, there isn't really a benefit to a low-flow fixture on the bathtub faucet. You should put in just the showerhead in your calculator and just its usage/flow rate (1.5 gpm).
