Latest Draft of LEED Rating System Revisions Now Open for Comment

Print Print this Article | Send to Colleague

The United States Green Building Council (USGBC) has released its fifth draft version of the LEED v4 Rating System. The comment period, which is open until Monday, December 10, is the last step in the program delivery process and development of the LEED update. NRMCA will review the draft and provide comments for those sections of the LEED system that affect concrete applications.

LEED v4 includes changes to all major LEED rating systems that affect new construction, existing construction, homes and neighborhoods. Many of the credits from previous drafts such as Life Cycle Assessments and Type III Environmental Product Declarations (EPDs) remained while Material Sourcing (extraction) and Material Ingredients disclosure has evolved dramatically. Once the comment period process concludes, LEED v4 will be balloted next June to its membership for adoption in 2013.

NRMCA members are encouraged to review the public comment draft on USGBC’s Web site. NRMCA will provide follow up articles regarding potential changes affecting our industry.
