In the above "Checklist" tab it states the following language:
Commercial Interiors projects must include in the water-use calculations any water fixtures that are being used by occupants, even if the installation of the fixtures is not within the scope of the project. For example, an office project that is not updating the base buildingwill still need to include the core bathroom fixtures in the LEED water use calculation.
However, in a review comment, GBCI says the following:
All applicable fixtures located within the LEED-CI project boundary as well as fixtures located outside of the LEED-CI project boundary which are installed or modified as part of the scope of work must be included in the calculations for the prerequisite.
These statements seem to contradict. One is saying to include all fixtures the occupants are assumed to use even if outside scope and other says to only include those fixtures installed or modified in or outside scope.
Does anyone have insight into this? I am so confused by this. The core bathrooms in our project is not in the scope of work and the team is only installing kitchen faucets in the LEED-CI project scope. Can we only include those kitchen faucets? Or do we need to also include the core bathrooms even though we do not have any control over them?
Thank you in advance! This has been driving me crazy.

Hi Courtney,
Assuming your project was registered after July 19, 2010, and did not install or modify any fixtures in the base building restrooms, then the calculations for WEp1 only includes fixtures within the tenant space/LEED-CI Project Boundary (the kitchen sink). However, the calculations for WEc1 must include all fixtures that are used by the LEED-CI project occupants (both within and outside of the LEED-CI project space).
Also, be sure to review the USGBC Additional Water Use Guidance Document as well which outlines FAQs relative to the July 2010 Addenda for both WEp1 and WEc1.
Hope this helps!

Thanks, Carlie. I really appreciate it.
And this is because you could achieve ridiculous savings simply from installing just one high performing fixture in the tenant space?

FWIW I think the credit language tab here should be updated to reflect any changes that have come about in the CI redline for 2009 projects. Courtney I think what you say above is part of it, I also think that from a practical standpoint GBCI had to start monitoring base building fixtures that tenants would be using, since there are so many tenant improvement projects out there that don't touch base building bathrooms, showers, etc.. even though they use them regularly.
EDIT: I came here looking for confirmation of the same thing (requirements to include both tenant and base building fixtures), and while I didn't find it here, the newer versions of the forms make it pretty clear. If project teams intend to only include tenant fixtures even though they will be using base building fixtures, they can still satisfy the prerequisite, they just can't pursue any points under WEc1. At least that's my takeaway from looking at the form a little more closely.

The credit language and checklist here is up to date, FYI.
