Washington, D.C.—The 2012 International Green Construction Code (IgCC), released today, will increase the energy-efficiency of structures, while providing governments direction and oversight of green design and construction, according to the International Code Council (ICC), the code’s author and one of several U.S. Green Building Council (USGBC) partners in the effort. USGBC, makers of the LEED green building certification system and co-authors of ANSI/ASHRAE/IES/USGBC Standard 189.1, applauds this new model code that serves as an important new policy option for state and local governments looking to codify green building practice.
More than 45,000 projects are currently participating in the commercial and institutional LEED rating systems, comprising 8.4 billion square feet of construction space in all 50 states and 120 countries. In addition, nearly 19,000 residential units have been certified under the LEED for Homes rating system, with over 75,500 more homes registered. The 2012 IgCC, which incorporates the 2011 version of Standard 189.1 as an optional path to compliance, offers a new code baseline that can be tailored by state and local governments to share many of the benefits of green buildings with the millions of buildings that are designed, constructed and renovated to meet minimum code, whether or not they are engaged in the LEED program
The 2012 version of the IgCC—authored by ICC in partnership with the American Institute of Architects (AIA), ASTM international (ASTM), ASHRAE, the Illuminating Engineering Society (IES), and USGBC—is an important first step for the partner organizations and the building community in a long, but important journey to mainstream healthier, lower impact, more efficient and responsible building practice
For more than 100 years, building codes in the United States have evolved to incorporate critical safeguards for building occupants based on the most current building science. More recently, communities have been calling for a regulatory tool that complements voluntary rating systems by offering jurisdictions minimum safeguards to protect against building-related risks to human and environmental health. Several state and local jurisdictions are already moving in this direction by putting into place early versions of the IgCC that were released during the development of the code. As building codes broaden their scope and establish a higher floor, USGBC continues to raise the ceiling through advances and refinements to LEED and associated programs. LEED version 2012 will be released in November 2012.
