To reduce indoor water consumption.
Building Water Use
For the fixtures and fittings listed in Table 1, as applicable to the project scope, reduce aggregate water consumption by 20% from the baseline. Base calculations on the volumes and flow rates shown in Table 1. All newly installed toilets, urinals, private lavatory faucets, and showerheads that are eligible for labeling must be WaterSense labeled (or a local equivalent for projects outside the U.S.).Projects where fixtures or fixture fittings are not within the tenant spaces are exempt from this prerequisite.
