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?

Schools-2009 WEp1:Water Use Reduction—20% Reduction

Adjustable valve for WC fixtures

Dear all, The project has 2/4 LPF WC fixtures specified, and the water calculations done accordingly. The Contractor is suggesting a WC fixture with a maximum flush rate of 3/6 LPF, but with a regulating valve that can decrease the flush rate down to zero. In other words, the WC fixture can be adjusted to provide 2/4 LPF, but can be easily adjusted later on to a higher non-compliant flow rate. Has anyone had experience with the USGBC with such types of WC fixtures? Thanks..

George, I think USGBC would tend to assume that the fixture flow rate may be adjusted upwards in the future, and would have you assume the higher rate in your LEED documentation. I would encourage equipment that cannot have that adjustment.
