This credit rewards project buildings that exceed the requirements specified in WEp1: Minimum Indoor Plumbing Fixture and Fitting Efficiency.  Additional points are earned if the performance calculations indicate that indoor potable water usage is at least 10% less than indicated in the credit baseline. Projects may be awarded an innovation point for exemplary performance by achieving a potable water savings of 35% or greater.

To earn this credit, start with the efficiency assessment completed for WEp1, then evaluate what changes, if any, are needed to meet the project’s water conservation goals.
