FAQs about WEc3 :

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?

Does anyone have experience with using a 1 gpm aerator in a residential setting? We typically use 0.5 gpm aerators in commercial settings which has worked fine. However, I'm concerned that a 1 gpm aerator will not have sufficient pressure to clean toothbrushes, razors, etc.

The pressure should be the same with less water. I don't think there should be any issues with using 1 gpm aerators.

Jeremy, You might want to check out the WaterSense guidelines and tested fixtures they approve for use in private bathroom. They suggest between 0.8 and 1.5 gpm for private lavatories where tooth brushing and other gunky business takes place: http://www.epa.gov/watersense/docs/faucet_spec508.pdf
