Maximize water efficiency within tenant spaces to reduce the burden on municipal water supply and wastewater systems.
For projects with water use fixtures in the scope
Employ strategies that in aggregate use 30% less water than the water use baseline calculated for the building (not including outdoor irrigation for landscaping) after meeting the Energy Policy Act of 1992 fixture performance requirements. Calculations are based on estimated occupant usage and shall include only the following fixtures and fittings (as applicable to the building): water closets, urinals, lavatory faucets, showers, kitchen sinks.
Employ strategies in aggregate use 30% less water use baseline calculated for commercial equipment performance requirements as listed in the Table below. Calculations are based on estimated occupant usage and shall include only the following fixtures (as applicable to the building): clothes washers, dishwashers,
ice machines, food steams, pre-rinse spray values, and combination ovens.
For equipment not addressed by EPACT 92 or the table below, additional equipment performance baseline requirements may be proposed, provided that documentation supporting the proposed benchmark or industry standard is provided.

For projects with no water use in the scope
The credit can be achieved if the base building fixtures used by the occupants of the project comply.
FTE: Maximum full-time shift equivalent numbers for both employees and customers can be determined in the following three ways. In all three a 50/50 ration of male to female should be used:
1. Actual or Historical data
3. If there is no actual data or projections, the following chart can be used:
Note for Calculation: Large Format Retailers are defined as greater than 50,000 square feet.
