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?

Hi!! My project is planning to use Jacuzzi as one of the sanitary fitting in the master room. I got a question about what is the baseline flow rate for Jacuzzi in calculation and which guideline should I refer to? Should I use the residential showerheads with 2.5 gpm as listed in LEED guideline? Thanks.

is not regulated...does not go into WEp calcs...for energy modelling the baseline = proposed for water and equipment usages pertaining to it.
