To reduce potable water consumption and the associated energy consumption and carbon emissions required to treat and distribute water, and to preserve potable water resources through an efficiency-first approach.

REQUIREMENTS

Achievement pathways	Points
Existing Buildings	1–14
Water Performance	1–14

Points are awarded based on total potable water consumption during a 12-month reporting period using the metric of gallons per square foot per year (or liters per meter per year). To earn one point, meet the baseline water use intensity threshold for the applicable space type as shown in Table 1. To earn additional points, demonstrate a percent reduction from the baseline water use intensity threshold as shown in Table 2.
