LEED‐CI projects that do not have any plumbing fixtures or fittings in the tenant space are exempt from WEp1. Even if off-site showers are being used to earn SSc3.2, they must be included in calculations for both WEp1 and WEc1.

When a project has replaced some of the core fixtures, they have essentially brought those fixtures into their LEED-CI project scope of work. If they wish to take credit for the new fixtures in the base building, all fixtures within the core restrooms must be included in the calculations for the prerequisite and credit. If they have registered before the July 19, 2010 Addenda applying to WEc1, the team can exclude the core restrooms in their entirety (which would mean excluding the newly installed fixtures), since in the past projects could earn this credit based solely on their tenant fixtures.
