Projects should refer to the following credit compliance guidance when planning for recertification. The table outlines the establishment and performance requirements and details the preferred frequency and duration of each performance requirement. Recertification is based on compliance with performance requirements. For the complete set of guidance, refer to the LEED for Existing Buildings: Operations & Maintenance Recertification Guidance.

|WEc1.2: Water performance measurement—submetering||Building components and site infrastructure
Have in place meters for one or more water subsystems.
Maintain continuous manual or data-logged meter readings. Provide at least weekly meter readings or weekly trend analysis from most recent 25% of recertification performance period.
