FAQs about WEp1 :

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?

Can I include process water savings in order to earn an Exemplary Performance point?

We are using the Kohler faucet with 1.5 gpm aerator for pantry sink, I asked the supplier for .5gpm aerator, he said lowest Kohler offers on this faucet is 1.5 gpm. Will the 1.5 gpm work for this credit?

Lee, technically you can use this on the project but since it's over the expected threshold, it will set you back in terms of meeting the credit requirements. I would recommend searching more deeply for a low-flow fixture.
