REQUIREMENTS EXPLAINED

This credit rewards projects that annually reduce potable water consumption compared to a baseline water use intensity for the specific building type. Projects can optimize points by upgrading to high-efficiency fixtures and fittings, monitoring meters and sensors for leaks, and taking corrective actions to reduce wasted water use. Using alternative water sources, such as municipally reclaimed water for flush fixtures or harvested rainwater for irrigation, can improve a project’s water performance by replacing potable water with these alternative sources.

Data Collection

Determine the project’s total water consumption from potable water sources. Water from alternative water sources is excluded from the calculation.

Report annual consumption for the 12-month reporting period, using data from meters of all potable water sources serving the project per WEp1: Water Metering and Reporting . If using utility bills to determine the water consumption, ensure the readings reported on the utility bills are actual readings and not estimates. When reporting the data, teams must confirm there are no gaps or missing data from the 12-month period.
