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?

Do sinks in Massage & Wash Rooms count in the WEp1 credit for LEED-CI? Currently, there is one massage room and one wash/dry room planned in my project. Both rooms include sinks. How would the use per day be determined if it is required?

Kirstin, the fixtures covered by this credit are those regulated by the EPAct 1992, so that includes lavatory sinks. If the sinks in those rooms are lav sinks, they would be counted.As for uses per day, would the tenant be able to give you an idea of that based on how many sessions take place per day, and how many times the sink is used per session, or some such method?
