A major update of the LEED rating system for commercial buildings has been approved by members of the U.S. Green Building Council to be introduced in 2009, the USGBC has announced.
The update, known as LEED 2009, is the "next major evolution of the existing LEED rating systems for commercial buildings," according to USGBC. It includes a series of major technical advancements focused on improving energy efficiency, reducing carbon emissions and addressing other environmental and human health outcomes, USGBC added.
Major changes in the LEED commercial building rating system include:
Incorporation of regional credits, extra points toward certification that have been identified as priorities within a project's given environmental zone.
A scientifically grounded re-weighting of credits, changing allocation of points among LEED credits to reflect climate change and energy efficiency as urgent priorities.
