ICC collaborated with cooperating sponsors – the American Institute of Architects (AIA) and ASTM International (ASTM) on the initial development of IgCC Public Version 1.0. AIA and ASTM played a vital role in the development of the IgCC: the AIA presence ensured a focus on their 2030 Carbon Neutrality Goal, while ASTM International, which carries a worldwide reputation as a standards developer, solidified the scientific basis behind the IgCC. ASHRAE, the U.S. Green Building Council (USGBC) and the Illuminating Engineering Society (IES) joined the ICC/AIA/ASTM team in developing the IgCC. ASHRAE Standard 189.1-2011 is included as an optional path to compliance within the IgCC.
Public Comment hearings for the initial version of the IgCC were held in Chicago, IL in August 2010. The IgCC Public Comment Committee reviewed and voted on proposed revisions to Version 1.0, moving development to Version 2.0, issued in November 2010.
Selected changes to the 2012 IgCC from Version 2.0
can be found here.
The final provisions in the 2012 IgCC were completed during the Final Action Hearing
in October 2011, in Phoenix, AZ.
