“LEED 2009” focuses on energy and carbon performance of buildings, transparent “weightings” and regional LEED credits

On May 19th the U.S. Green Building Council (USGBC) opened the first public comment period on LEED 2009, the next evolution of the LEED green building certification system. LEED 2009 represents a reorganization of the existing LEED rating systems for commercial buildings, combined with a series of major technical advancements focused on improving energy efficiency, reducing carbon emissions, and addressing other environmental and human health outcomes.
