WASHINGTON — The U.S. Green Building Council (USGBC) has announced that the third public comment period for the proposed 2012 update to its Leadership in Energy and Environmental Design (LEED) green building program will open on March 1, 2012. The comment period will close on March 20.

“LEED sits at the core of the green building movement, and is critical in realizing our collective mission,” said Scot Horst, senior vice president of LEED, USGBC. “LEED’s strength comes from its continuous evolution. This continuous improvement is the outcome of thousands of technical volunteers working to develop the program and the adaptability of the program to technological and market changes.”
