FAQs about WEp1 :

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?

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?

CS-2009 WEp1:Water Use Reduction

public non-potable water

Hi, WEc1 Water Efficient Landscaping allows the use of "water treated and conveyed by a public agency specifically for nonpotable uses" for the water saving calculations. Is the same strategy valid for WEp1 Water Use Reduction and related credits? Thanks in advance,

According to LEED Interpretation 1551, use of treated wastewater supplied by a municipality cannot be applied to WEp1 and WEc3 (LEED NC). This alternate water source can be used to contribute to the landscape irrigation credit. Site-derived nonpotable water can be used to contribute to WEp1 and WEc3.
