NC-2009 WEp1: Water Use Reduction—20% Reduction
Working on my 1st project that includes a pre-rinse spray faucet for a restaurant/cafe type setting. What should should be shown as the total daily uses and the duration on the template? We know the gpm.

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 Sheryl,
The LEED Reference Guide for Green Building Design and Construction, 2009 Edition (Updated June 2010) 11/1/2011 Addenda clarifies that for projects with commercial pre‐rinse spray valves, there is no longer a baseline performance standard from which to claim savings; rather, the prerequisite requires only that the flow rate comply with the ASME A112.18.1 standard of 1.6 gpm or less.
Hope helpful!
