The International Code Council (ICC), the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), the U.S. Green Building Council (USGBC), and the Illuminating Engineering Society of North America (IES) – all members of the American National Standards Institute (ANSI) – have announced the launch of the International Green Construction Code (IGCC).
The IGCC represents the merger of two national efforts to develop adoptable and enforceable green building codes. It will provide the building industry with language that both broadens and strengthens building codes in a way that will accelerate the construction of high performance green buildings across the U.S.
For decades, ICC and ASHRAE have worked to develop codes and standards that become the industry standard of care for the design, construction, operations and maintenance of residential and commercial buildings in the U.S. and internationally. In coordination with the efforts of ICC and ASHRAE, USGBC has been leading a nationwide green building movement centered on the LEED Green Building Rating System since LEED was launched in 2000. The convergence of these efforts in the IGCC is perhaps the most significant development in the buildings industry in the past 10 years.
Leveraging ICC’s unrivaled delivery infrastructure to reach all 50 states and more than 22,000 local jurisdictions and ASHRAE, USGBC and IES’s technical strengths, this partnership will accelerate the proliferation of green building codes and standards developed jointly by ICC, ASHRAE and USGBC and IES, across the country and around the globe. The newly launched IGCC establishes a previously unimaginable regulatory framework for the construction of high performance commercial buildings that are safe, sustainable and by the book.
A landmark addition to the technical content of the IGCC is the inclusion of ANSI/ASHRAE/USGBC/IES Standard 189.1, Standard for the Design of High Performance, Green Buildings Except Low-Rise Residential Buildings, as an alternate path of compliance. Standard 189.1 is a set of technically rigorous requirements, which like the IGCC, covers criteria including water use efficiency, indoor environmental quality, energy efficiency, materials and resource use, and the building’s impact on its site and its community. Standard 189.1 was written by experts representing all areas of the building industry, who contributed tens of thousands of man hours. Developed in a little over three years, the standard underwent four public reviews in which some 2,500 comments were received.
