• Commercial kitchen (if the kitchen serves at least 100 meals per day of operation)

  • Laundry, if the project includes commercial laundry equipment that processes at least 120,000 lbs. (57,606 kg.) of laundry per year or if the project includes a public laundry room)

The tenant must be able to access the submeter data in real time via local network, building management system (BMS), cloud service, app, or online database. All submeters must be capable of recording data at least hourly.

AND/OR

Option 3. Leak Detection Sensors (1 point)

Install permanent water flow meter/sensors for at least 50% of the project flush fixtures in the tenant space; water sensors can be installed on each flush fixture or for a group of flush fixtures (e.g., one per restroom facility).

The leak detection system should be able to identify a leak triggered by abnormal flow rate above normal range, or physically detect a water leak, and initiate an alarm upon a leak detection.

The tenant must be able to access the sensor data in real time via local network, BMS, cloud service, app, or online database.

Develop an action plan that addresses how the tenant will have access to data in real time and how the tenant will address and remedy any detected leak.

REQUIREMENTS EXPLAINED

The credit encourages projects to develop water metering and submetering strategies. Projects pursuing this credit must install permanent water meters or have access to data from existing meters, submeters, and sensors necessary to report and track water use for applicable subsystems.

Option 1 requires permanent meters or submeters on all water-using systems within the tenant spaces. Option 2 requires the use of permanent meters or submeters for applicable subsystems. Option 3 requires installation of permanent leak detection sensors and data integration with the BMS or similar.

Submetering and leak detection strategies, when developed early in the design, provide significant benefits to the owner and design team. Teams can identify all water-using systems and prioritize submeters on major systems. Reviewing the systems during the schematic or
