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

Troubles filling the template

Hi, I'm working on a urban office building and have some troubles filling the template: - We will have automatic sensor for lavatories: how can I take it in consideration? Should I only have to put (IPC/UPC) conventional and the flow rate? If so, the percent reduction is very bad. - We will also have shower temporized to less than 300 seconds but if I change this duration, the percent reduction of water is lower: How should I take it in consideration? Thanks in advance for your help.

Thanks Tristan, I've already read it before but didn't have seen the answer for my first question about the automatic sensor. But know I saw it and I've my answer. Thanks. But for the shower, I still don't find the answer!
