FAQs about 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?

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?

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

Fixtures to be included in WEp1 calculations

We have two lavatories to be used for medical purposes in our buldings: one in the esterelization room of an ambulatory and the other in a medical office. However, those two lavatories are of the same exact flow and type of the ones that will be used in our wcs. Should the consumption of those fixtures be included in the calculations, since the credit description says it "...should only include water closets, urinals, lavatory faucets, showers, kitchen sink faucets and pre-rinse spray valves"? In case we do have to include these 2 fixtures, what's the correct way to do it without double counting lavatories in the same group? We already created a group for the fixtures that will be used by the doctors. Thanks!

Hi folks, Haven't solved this issue yet... This is an automotive factory, a multiple building project. We are using the same fixture type for different purposes several times in this project, to mention a few: sinks in the sterilization room and medical room in the ambulatory, sinks for tools cleansing, sinks for production process related activities. Just want to make sure we are not leaving anything out from the calculations. Thanks

If the two WCs have the exact same flush rate, I would jsut combine them into one Fixture ID. Provide a narrative explaining that the fixtures have been combined because they have the same flush rate. If the fixture rates vary, you will have to separate them all out in the form. And you will have to figure out what percentage of occupants will use each fixture and adjust the Fixture Group Definition numbers accordingly.
