FAQs about WEp1 :

Can I include process water savings in order to earn an Exemplary Performance point?

Will the reviewers accept a spreadsheet as a plumbing fixture schedule in lieu of the plans from the Construction Documents?

In LEED review comments I've been referred to the Water Use Reduction Additional Guidance document. I didn't know this was a required reference document.

Should I include bar sinks? What about mop sinks or janitor sinks? Swimming pools? Safety showers? Bidets? Tub spouts?

We provided new showers in our project to comply with the alternative transportation credit. Should they be considered in WEp1 calculations?

Can you explain the 12-second duration for metering faucets?

Can I use a nonpotable water source to contribute to WEp1 compliance?

Our project does not have any eligible water fixtures in the project boundary. Can we comply with WEp1?

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?

Our project is a factory with historically a 95% male workforce. The restroom design accounts for this. Can I argue that the male/female gender ratio is different than 50/50?

Are shower duration controls an acceptable water-saving strategy?

NC-2009 WEp1:Water Use Reduction—20% Reduction

My office is working on a school renovation registered under LEED v2009 NC. I am wondering what the baseline water usage is for new plumbing fixtures replacing fixtures that were installed in the 1980s. Example, is 1.6 GPF for water closets still the baseline or would the baseline be what the original fixtures being replaced is? Thanks

Hello John, Yes, the baseline flow rate for water closets is 1.6 GPF. Projects must utilize the baseline flow rates outlined in the LEED 2009 BD+C Reference Guide (and not the flow rates for the current fixtures installed).
