The U.S. Green Building Council (USGBC) will update the LEED v4 green building certification program to “more directly address greenhouse gas emissions and climate change” according to the USGBC.
The update raises thresholds in LEED v4 to encourage greater energy performance and emissions reductions. It will be more closely aligned with the rigor of LEED v4.1, which increased energy performance requirements when it was released in 2018, USGBC says.
“The new updates to LEED v4 reaffirm that reducing climate change-related emissions is core to LEED,” said Peter Templeton, president and CEO, USGBC. “These updates ensure LEED continues to drive market leadership in addressing energy use and climate change across the built environment.”
LEED v4 initially focused on reducing energy demand through usage and efficiency. Meanwhile, LEED v4.1 introduced energy metrics on cost and greenhouse gas emissions—a first for LEED.
USGBC will post the updated LEED v4 requirements for public comment this month. Final updates would be presented to the USGBC membership for ballot approval and would go into effect for projects registered after the published effective date of the changes.
The next version of the LEED rating system will enter the development phase in January 2023.
