USGBC makes updates to LEED v4
San Francisco, California – The US Green Building Council (USGBC) has updated the major version of its LEED green building certification program, LEED v4, to address carbon emissions and climate change more directly. The updates will raise the threshold of LEED v4 to encourage better energy performance, and align LEED v4 with the rigor of LEED v4.1, which, according to the USGBC, raised the bar for energy and climate when released in 2018.
“From day one, USGBC is committed to the continuous improvement and improvement of green building standards,” said Peter Templeton, USGBC president and CEO. “The new updates to LEED v4 confirm that climate is at the heart of LEED. LEED certification has been a critical tool to help organizations build and improve the conditions of today’s buildings that address climate change.”
With the change, Building Design and Construction (BD+C) and Interior Design and Construction (ID+C) projects will be able to demonstrate energy performance improvement using LEED v4.1’s metric of energy costs or GHG emissions alongside LEED v4’s original energy source , according to the USGBC.
For the past nine years, LEED v4 has been the primary and approved version of the LEED green building certification. However, the guidelines for reducing energy demand focused first on utilization and efficiency. Meanwhile, LEED v4.1 introduced energy metrics for costs and greenhouse gas emissions, a first for LEED. Together, both LEED v4 and LEED v4.1 adopt the evolving needs of the market and build on previous versions of the LEED rating system, according to the USGBC.
The next version of the LEED rating system will enter development in January 2023 and will be guided by the Future of LEED principles, developed after months of discussions involving the global LEED community, according to the USGBC. The call for volunteers will open in December 2022.
