Intent
To support water management and identify opportunities for additional water savings by tracking water consumption.
Requirements
Establish permanently installed meters for at least two water subsystems through the following:
- Irrigation: Meter water systems serving at least 80% of the irrigated landscaped area.
- Indoor plumbing fixtures and fittings: Meter water systems serving at least 80% of the indoor plumbing fixtures and fittings, either directly or by deducting all other measured water use from the measured total water consumption of the building and grounds.
- Cooling towers: Meter replacement water use of all cooling towers serving the facility.
- Domestic hot water: Meter water use of at least 80% of the installed domestic hot water heating capacity (including tanks and on-demand heaters).
- Reclaimed water: Meter reclaimed water, regardless of rate. A reclaimed water system with a makeup water connection must also be metered so that the true reclaimed water component can be determined.
- Other process water: Meter at least 80% of expected daily water consumption for process end uses, such as humidifiers, dishwashers, clothes washers, and pools.
All meters, including whole-building meters, must be recorded at least weekly and used to regularly analyze time trends. If the building owner, management organization, or tenant owns the meter, it must be calibrated within the manufacturer’s recommended interval.

Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.
