Building-Level Water Metering: A Key to Sustainable Water Management in LEED NC and LEED CS Projects

Published by firstgreen on

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:

  1. Measure the total potable water use for the entire building.
  2. Record data at regular intervals (hourly, daily, or monthly) to allow for detailed analysis.
  3. 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:

Building-level water metering is a critical component of sustainable water management in LEED NC and LEED CS projects. By monitoring and managing water consumption, building owners and operators can identify opportunities for water-saving strategies, optimize water use, and contribute to a more sustainable built environment. Ensuring proper documentation and commitment to sharing water usage data with the USGBC is vital for achieving the Building-Level Water Metering credit and improving the overall performance of green buildings.
