How to comply with the prerequisite?
Or does that mean that this project is not elegible for LEED?

Can you explain the 12-second duration for metering faucets?
Can I use a nonpotable water source to contribute to WEp1 compliance?
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?
Are shower duration controls an acceptable water-saving strategy?
Can I include process water savings in order to earn an Exemplary Performance point?

Dear Tristan, although the additional guidance only refers to use of non portable water in retail & healthcare, can we use this method for office space as well. Please confirm.
Thank you

you are exempt from WEp1 if the tenant does not add plumbing into their space. If the tenant wants to go for WEc1, they need to include the core bathrooms. You can read more about this in the WEc1 birds-eye view.
