FAQs about WEp1 :

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?

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?

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

Aerators use in water flow fittings

Hi, Currently we are working in a office project. For the aesthetic purposes the project owners has selected flow fittings which does not meet the LEED requirement. Therefore they have agreed to use aerators and flow restrictors in their flow fittings to comply LEED requirement. The aerator brand they are using is Neoperl. For LEED submission we can provide spec sheets of both water fittings and aerators. Our question is do we have to provide a third party test report to clarify the flow rates after they are installed with the aerators apart from the spec sheets? Thank you.

Magda, You should be fine with spec sheets as long as they specifically state the flow rate for the fixture. Otherwise, the plumbing fixture schedule or project specifications with make/model and flow rates for the faucet and aerator are acceptable forms of documentation.

Hi Gerren, Thank you. We have spec sheets for both fixtures and aerators. I hope we are going to be fine with them in the submission.
