Public comments are being invited on the LEED rating systems developed by the US Green Building Council from now until June 22.
The next evolution of the rating system will be titled LEED 2009 and will involve a reorganisation of the existing approach for commercial buildings alongside measures to focus on improving energy efficiency, reducing carbon emissions and addressing other environmental issues.
Scot Horst, chairman of the volunteer LEED steering committee, said: “Continuing to seek the right balance between technical advancement and market transformation was a driving force behind the LEED 2009 work.
“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.”
