CI-2009 WEp1: Water Use Reduction—20% Reduction
Does GBCI recognize dual-flush valves (1.1/1.6 gpf) for water use reduction? If so, how do we document this on the template?

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?

Hi Laura,
Yes, GBCI recognizes dual flush valves for water use reduction. On the credit template, under flow fixtures, there is a drop down selection for dual flush valves. For the flush rate, you will need to use the equivalent flush value depending on usage. The Water Use Reduction Additonal Guidance document (link above under Birds Eye View / Key Guidance from USGBC) provides information detailing how to calculate the equivalent flush value.
