Core and Shell projects, this only applies to flush fixtures within the project’s scope of work.
- Each makeup water system (e.g., cold water inlet for domestic hot water, swimming pools, chilled water systems, and process water systems).
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 facility manager and/or tenant(s) 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 building manager or tenant will have access to data in real time and how the building manager and/or tenant(s) will address and remedy any detected leak.
REQUIREMENTS EXPLAINED
This credit encourages projects to further develop water submetering beyond the WEp1: Water Metering and Reporting requirements. Projects pursuing this credit must permanently install submeters and sensors. These tools are necessary to report and track water use for applicable subsystems. Option 1 requires submeters on all water-using systems within the project boundary. Healthcare and residential projects have project-specific requirements to meet the Option 1 requirements. Option 2 requires leak detection sensors and data integration with the BMS, or something similar.
Projects can only achieve one point for choosing either Option 1 or Option 2 of this credit.
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 for major systems.
Option 1. Submeters
Teams must install submeters for all of the following water-using subsystems, as applicable to the project: indoor plumbing fixtures and fittings, irrigation systems, make-up water systems, commercial kitchen water use, and laundry water use. WEp2: Minimum Water Efficiency addresses cooling tower submeters.
