USGBC has opened the second public comment period for the proposed 2012 update to its LEED green building rating system. The comment period, which will close on September 14, 2011, is the next step in the continuous improvement process and on-going development of the LEED program.
Updated LEED rating system drafts and responses to comments received during the first round of public comment period are posted for review and comment. As promised at the outset of first public comment, the credits in the proposed LEED 2012 rating systems have been allocated points based on a weighting process similar to the process used in 2009, but based on impact categories developed by USGBC specifically for use in LEED. These impact categories more directly align outcomes sought by LEED with USGBC’s market transformation goals. The weightings/point allocation process informed many changes in the rating system, including organizational changes proposed for the Indoor Environmental Quality (IEQ) and Materials and Resources (MR) credit categories.
