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?

Flow restrictors / aerators documentation

Hi all! I would like to ask about documenting flow rates for aerators used in projects. 1) Is there some specific requirement that the aerator needs to comply with or is a manufaturer's declaration on its flow rate sufficient? I do not have it in english so I need to translate it yet. Question is if it is enough? 2) I think it doesn't need to be WaterSense certified yet, does it? 3) Are there any requirements on testing methods to determine flow rate? Thanks for your opinions... Petr

Petr, the manufacturer's specifications should be sufficient for documentation. Watersense is not required, and there is no specific testing protocol.
