ATLANTA — In a deal nearly two years in the making, the International Code Council (ICC) and ASHRAE signed the final agreement that outlines each organization’s role in the development and maintenance of the new version of the International Green Construction Code (IgCC) sponsored by the American Institute of Architects (AIA), ASHRAE, ICC, the Illuminating Engineering Society (IES), and the U.S. Green Building Council (USGBC). The code, scheduled to be released in 2018, will be powered by ANSI/ASHRAE/ICC/IES/USGBC Standard 189.1, “Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings,” developed using the American National Standards Institute (ANSI)-approved ASHRAE consensus process. The joint Standing Standards Project Committee 189.1 (SSPC) will serve as the consensus body that will work to ensure the standard is consistent and coordinated with the ICC Family of Codes.

The ICC will be responsible for Chapter 1, Scope and Administration. For the 2018 IgCC, ICC will coordinate the technical provisions developed by ASHRAE with the provisions in Chapter 1 of the 2015 IgCC. As a result, the 2016 Group B Cycle will not include Chapter 1 of the IgCC for code changes. With ASHRAE developing technical provisions, ICC’s 2017 Group C cycle to develop the 2018 IgCC has been cancelled. Part of the development process for the 2018 technical provisions will include the SSPC review of the 2015 IgCC and consideration of content for inclusion in 189.1-2017 along with changes generated by committee and proposals submitted by stakeholders. Following the completion of the 2018 IgCC, Chapter 1 of the IgCC will be developed by ICC using its consensus code development process.

“Our goal in this partnership all along has been to share resources to increase use of the IgCC and make it simpler for code officials, designers, and contractors to build environmentally efficient structures that will lessen energy and water consumption and reduce the carbon footprint,” said Guy Tomberlin, board president, ICC. “We are now situated to do just that. We thank our partners, ICC members, and all who will contribute to the development of the IgCC powered by 189.1.”

“The full integration of Standard 189.1 will serve as the technical content of the IgCC to leverage ASHRAE’s technical expertise and increase the standard’s influence on sustainable buildings,” said David Underwood, president, ASHRAE. “We look forward to continuing to engage a broad spectrum of stakeholders in the development of Standard 189.1 following the ANSI consensus standards development process. The result will be a comprehensive compliance tool that can be used by jurisdictions worldwide that are committed to a more sustainable built environment.”

The new publication also will align the Leadership in Energy & Environmental Design (LEED) rating system program to ensure a streamlined, effective set of regulatory and above-code options. The green building certification program recognizes best-in-class building strategies and practices. To receive LEED certification, building projects must satisfy prerequisites and earn points to achieve different levels of certification.
