LEED v4, the latest version of the Leadership in Energy and Environmental Design guidelines for sustainable building, will make its official debut at the Greenbuild Expo in Philadelphia, Pa., November 20-22.

The U.S. Green Building Council (USGBC) voted to adopt the fourth version of the Leadership in Energy and Environmental Design (LEED v4), the next update to the green building rating system, over the summer. LEED v4 will officially launch at the Greenbuild International Expo and Conference and Expo, Nov. 20-22, in Philadelphia, Pa.

USGBC plans to offer education on LEED v4 in the form of webinar suites, and the full program, along with reference guides, will be unveiled at the Greenbuild Expo. After the launch, teams will be able to register their projects under the new system and access the tools and suite of resources that support it.

"This update of LEED builds on the past while offering new requirements, preparing all LEED projects to achieve higher levels of building performance and positive environmental outcomes," says Scot Horst, senior vice president of LEED for the USGBC. "This newest version of LEED challenges the market to make the next leap toward better, cleaner, healthier buildings. I am confident that people will also notice the improved usability of the system with an improved documentation process and more resources and tools to assist and support positive action."
