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?

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

temporized faucet

The water use reduction additional guidance says: the flow rate is determined using the flow rate in gallons per minute (gpm) and the duration setting (in seconds) for the metering faucet. When using metering sensor faucet or in default 12 second duration of flow representing the total of all run times during the hand washing process should be used. If I have a temporized faucet (clicle 6sec duration - 2.5 Liters / clicle), which is the value to be inserted into the template?

Although this is the subject of some debate, currently a time less than 12 seconds is not allowed. The logic is that this is the time water needs to run on your hands for hygienic handwashing. The amount of times the object cycles to effect this is irrelevant.
