FAQs about WEp1 :

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?

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?

If the fixtures are part of the project scope, then they should be included in the water use calculations. Are they part of the design and just delayed in installation?

Yes, the fixtures are delayed on install. So the question is whether move-in and use of existing standard fixtures would affect the calculations.

Hello, I don't have a clear picture on this yet so maybe someone can help! Let me clarify the situation. Move-in has already occurred, but the project has not yet submitted. Certain plumbing fixtures have not been renovated and now there is an interest in doing so. Is it still possible to renovate these fixtures and include the new flow rates in the calculations as you would normally? Thanks!
