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?

I am working on a dormitory project that includes washing machines. The v2009 water use reduction calculator (process tab) has an option for commercial clothes washers, but not residential. Is it reasonable to model the residential clothes washers as compared to a commercial baseline? If not, can anyone point me to an appropriate baseline for residential washers? Thank you!

LEED-CI v2009 WEp1/WEc1 does not include washing machine water usage in its scope. That section is provided within the v2009 Calculator as it is a requirement of the LEED-Healthcare system. As such, you should not be including any of the process water calculations as it is simply not applicable to your project type.
