ASHRAE and the International Code Council have announced the release of the 2018 International Green Construction Code (IgCC) User's Manual. The manual provides readers an understanding of the requirements of the code and how those requirements may be met. The publication contains sample calculations, forms to demonstrate compliance, and references to helpful resources and websites.

"ASHRAE remains committed to providing sustainability strategies to improve indoor air quality and building performance," said 2020-21 ASHRAE President Charles E. Gulledge III, P.E. "The IgCC User's Manual offers a clear roadmap to the specific requirements of the 2018 IgCC with provisions that promote sustainable construction in an integrated fashion."

"As the demand for green building design, construction and operational techniques continues to grow, the IgCC remains one of the many strong solutions that help communities establish sustainable, resilient, high-performance buildings," added Code Council Executive Vice President Mark Johnson. "The new IgCC user's manual provides resources that aid the career development of building safety professionals, which is key to our efforts to welcome the next generation of industry leaders and lead the way to sustainable and resilient building."

The user's manual is intended to support the entire building industry, including architects, engineers, contractors, building officials, and other building professionals applying the 2018 IgCC. The publication offers a corresponding chapter for each chapter of the 2018 IgCC.

The 2018 IgCC was developed to align the technical requirements of ANSI/ASHRAE/ICC/USGBC/IES 189.1-2017-Standard for the Design of High-Performance Green Buildings Except Low Rise Residential Buildings, with the Code Council's multi-stakeholder IgCC. The 2018 IgCC — the first full integrated edition developed cooperatively by the Code Council and ASHRAE — is a unified code that emphasizes adoption, ease of use and enforcement for building projects. It helps governments streamline code development and adoption and improve building industry standardization.

The 2018 IgCC User's Manual is now available for preorder.
