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?

CS-2009 WEp1:Water Use Reduction

Baseline for Blow-out Fixtures

According to the Water Use Reduction Additional Guidance (April 2013), when selecting the "Blow-out fixture" option, the 3.5 gpf baselne should also be used for the installed case. But in my view, only the fixtures that consume water greater than 1.6 gpf should follow this rule. I have a project that the blow-out fixtures with 1.58 gpf will be installed in the project. Can I use 1.6 gpf as the baseline?

I would recommend erring on the side of using a 1.6 gpf baseline for any fixtures that consume less than 3.5 gpf, based on the definition provided in the Water Use Reduction Additional Guidance. However, I've not come across this on any projects myself and it would be great to hear from anyone with a similar situation (or, if you've submitted your project already, to hear how you ended up handling them)!
