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?

Hi, How should be the compliance (of 0.25gpc) for sensor based lavatory faucet be checked if the manufacturer mentions only “ adjustable from 1 - 20 minutes “ , the model in question is EAF-200-P-ISM(by SLOAN)

Mohammed, do you mean 1-20 seconds? The GPC should be base on 12 seconds of flow.

charles, you can refer the product data sheet at : http://www.sloanvalve.com/Specifications/Optima_Lino_EAF-200.pdf the data sheet states "Continuous Run — 2 minute default setting (adjustable from 1 - 20 minutes)"----this is all that it states with respect to sensor timing,

Mohammed, The faucet is designed only to operate when the users hands are within range of the sensor beam, and will shut off automatically after 2 minutes of continuous flow. "Water will flow until the hands are removed or until the faucet reaches its automatic timeout setting" The 1-20 minute run time is part of the of the "iq Click Feature", which is optional. This feature allows the user to change the automatic timeout setting of the faucet to 1 - 20 minutes. The spec does states that this feature is not recommend for public restrooms. GPC would still be calculated based on flow for 12 seconds.
