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?

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

Multi-Flow Showerhead

I am working on a project that plans to install a shower head with three flow options: 0.5 GPM-1.0 GPM -1.5 GPM. How do we account for multi-flow showerheads on the WEp1 form? This circumstance was not accounted for in the WEp1 Additional Guidance documentation.

Unless the fixture can be installed to limit water use and guarantee one of the lower flow rates, I would recommend using the 1.5 GPM (worst case scenario) in the calculations.
