ICC, ASHRAE Outline Roles to Consolidate IgCC and 189.1 in Response to Call from Industry

“IgCC Powered by 189.1” will provide the design and construction industry with the single, most-effective way to deliver sustainable, resilient, high-performance buildings

In a deal nearly two years in the making, the International Code Council (ICC) and ASHRAE have 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 the 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 ICC Board President Guy Tomberlin, CBO. “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 Executive Steering Committee for the effort to align 189.1, the IgCC and LEED consists of representatives of ICC, ASHRAE, USGBC, AIA and IES, and the SSPC Chair.

“The full integration of Standard 189.1 to serve as the technical content of the IgCC will leverage ASHRAE’s technical expertise and increase the standard’s influence on sustainable buildings,” noted ASHRAE President David Underwood. “We look forward to continuing to engage a broad spectrum of stakeholders in 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 satisfy prerequisites and earn points to achieve different levels of certification

“This joint initiative will forge the fundamental regulatory building blocks of green construction on which future green building leadership initiatives can grow,” said Brendan Owens, chief of engineering at USGBC. “It takes courage to think differently and to commit to a new model, and for that we thank the leadership of the partner organizations behind the IgCC powered by 189.1."

“Our combined membership, consisting of practicing design professionals, code officials, and the building industry representatives, supports the development of codes and standards that protect the health, safety and welfare of the public at large,” said AIA CEO Robert Ivy, FAIA. “Through this significant agreement, both the AIA and the ICC agree to work more closely to achieve our common goals.”

The new agreement between ASHRAE and ICC furthers the effort these organizations initiated in 2010 by providing the market with a single code that is coordinated with the International Family of Codes.

“IES looks forward to continuing to partner with ASHRAE in developing technical content for Standard 189.1,” according to Rita Harrold, IES representative, “and to participating with the other organizations in this unique collaborative opportunity to satisfy the goals for the new version of IgCC.”

The agreement creates a comprehensive framework for jurisdictions looking to implement and adopt green building regulations and codes. The unprecedented collaboration leverages the unique organizational expertise of the partners participating in this evolution of green building codes and brings AIA, ASHRAE, ICC, IES and USGBC into strategic and tactical alignment on the relationship between 189.1 and the IgCC. Other organizations that support this vision and would like to join the effort are invited to contact Dominic Sims at DSims@IccSafe.org or Jeff Littleton at JLittleton@ashrae.org.
