Water Metering

Install (or use existing) permanent water meters to monitor, record, and report the total water consumption for potable and alternative water sources for the building and associated grounds.

Report whole-project use for each type of water source supplied to the building and associated grounds with the following additional provisions:

• The facility manager and/or tenant must be able to access the meter data.

• Meter alternative water sources separately from municipally supplied potable water.

• Measure and report total water use for the entire 12-month reporting period.

• Commit to sharing with USGBC the resulting whole-project water usage data on an annual basis following certification.

REQUIREMENTS EXPLAINED

Measuring water usage within the project’s boundary allows facility managers complete transparency into actual water consumption. Tracking and reviewing water usage data allows the facility manager to identify inefficiencies in the building, create pathways to increasing conservation efforts on-site, and mitigate potential problems, including leaking pipes or valves, within water-using systems.

Projects must install or use existing meters and collect water consumption data (gallons or liters) from all water sources within the project boundary for the 12-month reporting period. This includes potable water sources and alternative water sources.
