It’s standard practice for most new buildings to install whole-building potable waterWater that meets or exceeds U.S. Environmental Protection Agency drinking water quality standards (or a local equivalent outside the U.S.) and is approved for human consumption by the state or local authorities having jurisdiction; it may be supplied from wells or municipal water systems. metering, which satisfies this prerequisite. Those projects simply need to record meter readings monthly, compile water use summaries, and commit to sharing water use data with USGBC for five years in order to meet the remaining requirements of this prerequisite.
GBCIThe Green Building Certification Institute (GBCI) manages Leadership in Energy and Environmental Design (LEED) building certification and professional accreditation processes. It was established in 2008 with support from the U.S. Green Building Council (USGBC). won’t ask teams to provide water use summaries at the time of certification, since that data won’t be available. To document this credit, you’ll need to confirm that compliant metering is in place, and provide a copy of the commitment letter stating that the project will share water data with USGBC going forward.
If your project design doesn’t currently include compliant water metering, you’ll need to ensure that a meter is added that measures water use for the LEED project building and grounds. Remember that the meter cannot be shared with another building. There are no special requirements for the meter type except that it must be permanent. Meter readings can be automated or manual.
USGBC has not provided a commitment letter template. However, Minimum Program Requirement 6 from the LEED 2009 rating system included a requirement for sharing water use data, which is outlined on Project Information Form 1. The language on the PIf1 form can provide teams with a good starting point for developing their own commitment letter.
To support water management and identify opportunities for additional water savings by tracking water consumption.
Install permanent water meters that measure the total potable waterWater that meets or exceeds U.S. Environmental Protection Agency drinking water quality standards (or a local equivalent outside the U.S.) and is approved for human consumption by the state or local authorities having jurisdiction; it may be supplied from wells or municipal water systems. use for the building and associated grounds. Meter data must be compiled into monthly and annual summaries; 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 or typical occupancy, whichever comes first.
This commitment must carry forward for five years or until the building changes ownership or lessee.
