NC-2009 WEp1: Water Use Reduction—20% Reduction
We are working on an interior rennovation of a multi-level office building with one owner/tenant. We are not touching the core, shell or landscape. As the core is where the restrooms are located, can the project be exlcuded the restrooms from WEp1?

Can you explain the 12-second duration for metering faucets?
Can I use a nonpotable water source to contribute to WEp1 compliance?
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?
Are shower duration controls an acceptable water-saving strategy?
Can I include process water savings in order to earn an Exemplary Performance point?

E H, the NC rating system covers the whole building scope. You cannot exclude fixtures not in the construction scope. You could do this for a CI project.

EH and Tristan - There was an addenda to address this issue for NC.
From the May 9, 2011 Addenda:
For additions to existing buildings, only the fixtures within the project scope must be counted for the prerequisite. To earn points under WE credit 3, all fixtures necessary to meet the needs of the addition occupants must be included, even if they are located within the existing building.
You are ok on the prerequisite but you can't get any points "all fixtures necessary to meet the needs of occupants using the addition must be included, including those located within the preexisting building." to get points under WEc3

The project is not an addition . . . So, I don't think it will qualify for the addenda. And, as the building has one owner/tenant with all floors interiors being renovated, I'm not sure it will fall under LEED CI . . .
