Consider establishing a detailed phase-out plan for any noncompliant equipment that remains in use.

Replace equipment in use with compliant models as needed to reach the minimum 20% implementation threshold.

Regularly maintaining equipment and following safety procedures is considered standard practice and, on its own, is not adequate to achieve this credit. The following are examples of qualifying features or best practices: 

Estimated occupant usage is determined by calculating the number of FTE occupants, as well as transient occupants, for the entire building, not just the tenant space. 

Calculations are based on the number of occupants that will use the plumbing fixtures and the fixture rates, not on the number of fixtures. 

This path applies to projects that occupy less than 50% of the total building area. If you occupy most of the building and don’t qualify for this option, consider pursuing WEc1: Water Use Reduction instead. 

This path covers the whole building’s water use, not just your tenant fit-out.

Aim to locate your tenant space in a building that has reduced its water use by 30% (for the entire building) and has instituted a plan to get future occupants to comply. 

Refer to LEED-NC WEc3 for detailed requirements and documentation guidance.
