"Continuing to seek the right balance between technical advancement and market transformation was a driving force behind the LEED 2009 work," explained Scot Horst, Chairman of the volunteer LEED Steering Committee, which leads the technical development of the LEED rating system. "The 'big ideas' we've proposed include transparent weightings of LEED credits so the highest-priority credits achieve the most points, a new mechanism for incorporating bioregional credits, and a more nimble framework that supports rapid response to emerging environmental and human health issues."
The LEED Green Building Rating System was developed by USGBC to drive market transformation in the building industry by defining a consensus metric for leadership in green building that forms a basis for continuous improvement. The evolution of LEED is based on technical, scientific and market-based advancements.
