the labor hours and material costs necessary to repair major damage. Leaks that are not addressed commonly cause higher bills.

Projects pursuing this option must install permanent water flow meters or sensors on each applicable subsystem (irrigation, flush fixtures, makeup water systems) within the project boundary. The devices must report abnormalities and generate an alarm at a local network, BMS, cloud service, app, or online database accessible by the facility manager and tenants.

Data access and action plan Providing access to and regularly performing reviews of the data optimizes an operator’s ability to address water leaks. Develop an action plan that addresses, at minimum, data access for operators and tenants, the approach for resolving detected leaks, and a communication plan to alert building occupants when repairs impact the building and the site.

Irrigation leak detection requirements Install devices at the point of entry to the site for permanently installed irrigation systems. This allows for the earliest possible detection of any leaks within the system.

Flush fixture leak detection requirements For the flush fixtures, install sensors or meters for at least 50% of the flush fixtures identified in WEp2: Minimum Water Efficiency . Install the device at the flush fixture for an individual toilet room, such as a unisex or family restroom. A single device that monitors all flush fixtures for group restrooms is acceptable.

Make-up water system leak detection requirements All makeup water systems must have permanent sensors or meters for leak detection. Leak detection must occur at each system. A sensor or meter that collectively monitors leaks for a single makeup line serving multiple systems does not meet the credit requirement.

Healthcare OPTION 1. SUBMETERS

Healthcare projects require additional submeters. Many processes typical of healthcare operations, such as sterilization, water use in surgical suites, and purified water systems, require significant amounts of water. The credit requires that healthcare projects meter an additional five subsystems, as outlined in the Rating System. For projects that do not have at least five additional subsystems within the project scope, provide meters for all applicable water subsystems included in the project.
