FAQs about 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?

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?

CS-2009 WEp1:Water Use Reduction

Existing fixtures

For an existing building undergoing major renovation how should the existing water fixtures be handled as far as WE prerequisite is concerned? Could existing fixtures if outside the scope of renovation be excluded from the calculations? Accordingly, should only fixtures to be upgraded and hence within the scope of renovation be included in the calculations? Thank you in advance.

I have the same question. Is it a matter of setting a project boundary that doesn't include the excluded the plumbing fixture?

As per 05/09/2011 for “additions to existing buildings, only the fixtures within the project scope must be counted for the prerequisite. To earn points under WE credit 3, all fixtures necessary to meet the needs of the addition occupants must be included, even if they are located within the existing building.” However, this addenda is not clear whether the “project scope” refers to the addition only or the entire building. And if it is a matter of setting a project boundary, could the LEED boundary which includes an existing building undergoing major renovation exclude the existing fixtures which are located within that building shell? Obviously, this problem refers to the flush fixtures only since flow fixtures can be easily renovated.
