Boston / Washington, D.C. — LEED 2009, the long-awaited update to the U.S. Green Building Council’s LEED green building certification program, has passed member ballot and will be introduced in 2009 as the next major evolution of the existing LEED rating systems for commercial buildings. It includes a series of major technical advancements focused on improving energy efficiency, reducing carbon emissions, and addressing other environmental and human health outcomes.

LEED 2009 will also incorporate regional credits — extra points that have been identified as priorities within a project’s given environmental zone. LEED has also undergone a scientifically grounded re-weighting of credits, changing allocation of points among LEED credits to reflect climate change and energy efficiency as urgent priorities.

LEED 2009 incorporates eight years worth of market and user feedback in the form of precedent-setting Credit Interpretation Rulings. Process innovation in how new technical advancements are incorporated into LEED will also be introduced alongside LEED 2009, including a “pilot process” for individual credits that will allow major new technical developments to be flexibly trialed, evaluated and incorporated into LEED.
