FAQs about 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?

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?

CS-2009 WEp1:Water Use Reduction

sanitary installations within tenant fit-out

Hello Our current core&shell project does not include sanitary installations, which will only be built at tenant fit-out stage. LOv3 for core&shell produces generic data based on our tenant recommendations. However these are not binding. Can anyone clarify this procedure?

Hi Jens, If your CS project does not include any regulated plumbing fixtures in the scope of work then I believe you would be exempt from WEp1 but cannot achieve any points under WEc3. However, if you want to achieve points under WEc3 for the LEED CS building then you will need to have a binding Tenant Sales and/or Lease Agreement. Please see the LEED Reference Guide for Green Building Design and Construction, 2009 Edition (Updated June 2010) Core and Shell Appendix 3 and 4 for additional information on the options available. Hope helpful!
