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?

CS-2009 WEp1:Water Use Reduction

Tenant lease clauses

If our project has a water reduction of 30% but is not installing any urinals or kitchen taps, what clauses should be included for the tenant? Should the tenant be obliged to install fixtures and fittings that, whenever calculated together with the fixtures we have installed, retain that 30% reduction?

Hello all, Can anyone help out with this? We are very confused as to what condition should be set for the tenants. Many thanks for your help!

When fixtures are not selected before DP submission, I usually ask mechanical engineers to require specs to achieve with 30% reduction. I am not sure completely, but I believe that you need to specify GPM/GPF of urinals and kitchen taps. If urinals or kitchen taps are not included in WEp1 calculation, reviewers will certainly will ask you to clarify it.
