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?

Hello, I am working in a project undergoing major refurbishment. It is my understanding that for major refurbishments assessed under NC existing water fittings need to be considered on both WE P1 and WE c3. Unfortunately the building I am assessing has no O&M manuals and therefore there is no information regarding the water consumption of the existing features. What would be the best way to evaluate the consumption in this scenario. Would actual measurement on site be acceptable? If so, what sort of evidences would we need to be provided? Thank you very much in advance. Regards Alicia

Alicia, you can conduct actual measurement of use. See our guidance on EBOM water credits for some additional input on this.
