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?

CS-2009 WEp1:Water Use Reduction

Preset lavatory faucets

In our project we have possibility to use preset lavatory faucets in which we can adjust preset flow rate. However, user may use temporarily higher flowrate by lifting the tap and after use faucet will return automatically to its preset flowrate. May we use the preset flowrate in water use reduction calculations?

Jukka, I would assume that this approach is not acceptable for LEED. In other cases I have seen that if there is any variation in the flow of a fixture, GBCI assumes (reasonably so, I think) that the maximum flow will be used.

What about urinals?. We are working in a project with urinals that could be adjusted.Can we consider that there is no issue with that as no one is going to change urinal flow?.

Belén, when are the urinals adjustable? Only upon installation? That sounds reasonable if you can include some assurance that they are installed at the required flush rate. But if they are easily adjusted by a user or maintenance person, I am not so sure.

Thanks Tristan. Urinals include an electronic control accesible from the exterior so we consider that we can't use this model. Best Regards
