The next phase in the development of the 2012 edition of the National Green Building Standard is now underway as the NAHB Research Center opened a 45-day public comment period for the draft standard on Sept. 23, 2011. The Research Center, an American National Standards Institute (ANSI) accredited developer, is serving as the administrator of the standard development process.

A PDF version of the draft standard, which includes all changes that were approved by the Consensus Committee, is available for download from  Instructions for submitting comments and details on the scope of the public comment period are provided on the Web-based submittal form, which is also available at  The deadline for submitting comments is Nov. 7, 2011.

The Consensus Committee, chaired by Don Pratt of Auburn Hills, Mich., is scheduled to meet the week of Jan. 23, 2012, at the National Housing Center in Washington, D.C., to consider, hear public testimony, and take formal action on the public comments. Once the committee has completed its work, the newly updated National Green Building Standard will be submitted to ANSI for approval in 2012.

Initiated originally in 2007 by the International Code Council and the NAHB, the 2008 National Green Building Standard was developed by a 42-member Consensus Committee and approved by the ANSI in January 2009, making it the first point-based rating system for green residential construction, remodeling, and land development to be approved by ANSI. As an ANSI-approved standard, the document is subject to periodic updates as a way to ensure that advances in building codes, technology, and other developments can be considered for incorporation.
