FAQs about WEc3 :

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 LEEDusers,

I have a technical question regarding WEc3 exemplary performance. Can somebody confirm requirement for exemplary performance in LEED-2009 NC USGBC reference guide or have ever pursued innovation credit for exemplary performance? IS it only limited to overall potable water reduction by 45% or innovation point can be earned by significant water saving in process water, as explained in LEED Canada 2009 reference guide?

LEED form on LEED ONLINE for LEED-2009 Healthcare does not provide overall water saving but separate water saving for flow&flush fixtures and process water. I am wondering even if I would like to report overall saving and earn exemplary performance, how should I proceed?

Our project has 55% process water reduction and 40% for flow and flush fixtures.

Hi Nirwair, I was wondering if your question was resolved?  I am working on a kennel project (NC 2009) that consumes a lot of process water (to wash animal cages, transportation vans, wet tables, etc). We are using reclaimed rainwater for a large part to limit the use of process water. Looks like registration for the pilot credit for Process Water is closed (https://www.usgbc.org/credits/new-construction-core-and-shell-commercial-interiors/v2009/wepc18) Is there a way to document Process Water savings for credit either through exemplary performance/a different innovation credit? Thanks in advance

Hi, The question was resolved after I got response from LEED reviewer saying "individual fixture has to meet this requirement, not overall". This is specifically true for healthcare projects only. If you have registered this pilot credit before closed date, you should be able to access it and submit it through LEED ONLINE. Nirwair
