| 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(s) must be able to access the meter data.
-
Meter alternative water sources separately from municipally supplied potable water.
-
Commit to sharing with USGBC the resulting whole-project water usage data at least annually. This commitment must carry forward for 5 years or until the building changes ownership or lessee.
The requirements may be applied to the project scope of work and exclude future tenant utility services and submeters that will be installed in the tenant scope of work.
REQUIREMENTS EXPLAINED
This prerequisite requires that projects install or use existing meters and collect water consumption data in gallons or liters from all water sources within the project boundary. This includes potable water sources and alternative water sources. Projects must also provide data access to facility managers, operations managers, tenants, and/or another appropriate people. In addition, projects must commit to reporting the total water consumption to USGBC at least annually. Share the data for five years, or until the building changes ownership or lessee.
