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?

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

Janitor / Mop Sink faucets

Hi all, I was surprised to receive a recent review comment for WEp1 noting that we had left out the janitor sink faucet in our calcs. As noted in LEEDUser and elsewhere, janitor sinks are not covered by the WE credits, neither are they included in NC 2.2. The reviewer did a simple re-calculation and told us we had lost a percentage point (35% to 34%) which means the loss of one point! I've submitted an inquiry straight to the review team, but wanted to ask if anyone else has received a similar comment. In addition, the observation regarding janitor sinks was not mentioned at our preliminary design credit review, only during our final review. What is the official stance regarding "new" issues raised during final reviews?

Janitor sinks are "Bucket Filling" sinks and shouldn't be included as you stated. I've never had this issue before. I don't see why the LEED reviewer isn't allowed to bring up new issues, however, it's never happened on one of my projects. They use the term "Anticipated" rather than "Approved" to allow themselves the ability to bring up new items.

Exactly my point--glad you agree. I have no problem with new comments being brought up when credit documentation itself changes between review phases, but in the case of final reviews, in the absence of any changes, it gets tricky. I would expect the onus to be on the part of the reviewer to spot these issues first time around, otherwise compliance becomes a moving target for the project team. A mid-review clarification request would be appropriate in cases like this. Wondered if anyone has had similar experiences.
