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

Daily Use of sink in Dorm Lobby

Hello, We are currently responding to initial preliminary advise and getting ready to resubmit our responses for a dorm building. However, we are uncertain as to how to evaluate daily usage for one of our sinks. We have a large open entry lobby/lounge that contains a counter with a single sink for when/if there are any gatherings in this space. This sink would most likely not be used on a daily basis by every resident and/or guests and could go days without any use. Is there a best way to calculate overall daily usage for this sink? Thanks in advance!
