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

Shower in Units of gpc or USgpm in Form WEp1

Hello, a question concerning WEp1 Could I use the flow rate in Units of gallons per cycle (gpc) instead of USgallons per minute (USgpm) for the Shower as Fixture Family in Table WEp1-4.Flow Fixture Data? The shower has a flow rate of 10 lpm or 2.64 USgpm (from product data sheet),that is more that the limit 2.50Usgpm. Can I convert the flow rate in gallons per cycle (gpc), which I mean 2,50 x (12/60)= 0.50 gpc (10 liter/minute)? Or is the conversion applicable only to lavatory faucet? Has anyone had a similar experience with Units for a shower as Fixture Family form WEp1? Thank you in advance.

Hello Panagiota, You should utilize the 2.64 gpm flow rate for your calculations. I am not aware of project teams being able to convert the shower fixture from lpm to gpc. While the flow rate is unfortunately above the 2.5 gpm baseline, note that the total water use reduction (in aggregate, for all combined flush/flow fixtures) must achieve a min. 20% reduction.
