Building-Level Water Metering: A Key to Sustainable Water Management in LEED NC and LEED CS Projects
Water scarcity is a growing global concern, and sustainable water management has become a priority for the construction industry. LEED (Leadership in Energy and Environmental Design) is a green building certification program that recognizes best-in-class building strategies and practices. Building-level water metering is a crucial aspect of LEED certification for New Construction (NC) and Core & Shell (CS) projects, as it enables building owners and operators to monitor, manage, and optimize water use.
In this article, we will discuss the importance of building-level water metering in LEED NC and LEED CS projects, the credit documentation requirements, and a quiz to test your knowledge on the topic.
Building-Level Water Metering in LEED NC and LEED CS Projects:
The Building-Level Water Metering credit encourages the installation of permanent water meters to measure and monitor the total potable water use of a building. By collecting data on water consumption, building owners and operators can identify opportunities for water-saving strategies and track the effectiveness of implemented measures.
LEED NC and LEED CS projects must install building-level water meters that meet the following requirements:
- Measure the total potable water use for the entire building.
- Record data at regular intervals (hourly, daily, or monthly) to allow for detailed analysis.
- Store data for at least three years.
Additionally, LEED projects must commit to sharing the collected water usage data with the USGBC (U.S. Green Building Council) for a minimum of five years.
Credit Documentation Requirements:
To comply with the Building-Level Water Metering credit, projects must submit the following documentation:
| Requirement | LEED NC | LEED CS |
|---|---|---|
| Building-level water meter | ✔ | ✔ |
| Water meter specifications | ✔ | ✔ |
| Data recording & storage plan | ✔ | ✔ |
| Commitment to data sharing | ✔ | ✔ |
