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?

We have a NC-2009 project were there is an automotive service area that has a washfountain for use by the mechanics only. They also have a locker room area with toilets, urinals, lav's, and showers. Should the washfountain be considered 'process water' because it is used for operational processes and not covered by EPAct 1992 or should it be included in the WEP1 calculations? Thank you!

You may want to review the conversations about commercial kitchens on this board. I believe the practice there has been to have the hand wash sinks align with LEED WEp1.
