LEED O+M: Existing Buildings | v4 - LEED v4

Building-level water metering



To support water management and identify opportunities for additional water savings by tracking water consumption.



Have permanently installed water meters that measure the total potable water use for the building and associated grounds. Metering of any gray or reclaimed water supplied to the building is encouraged but not required.


Record meter data on a monthly basis and compile; meter readings can be manual or automated.

Commit to sharing with USGBC the resulting whole-project water usage data for a five-year period beginning on the date the project accepts LEED certification.

This commitment must carry forward for five years or until the building changes ownership or lessee.
