ASHRAE has announced the release of the 2018 International Green Construction Code® (2018 IgCC®). The 2018 IgCC is a joint initiative of the U.S. Green Building Council (USGBC), International Code Council (ICC), ASHRAE and the Illuminating Engineering Society (IES).

The 2018 IgCC aligns 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 ICC’s multi-stakeholder IgCC. The goals of the updated code are to help governments streamline code development and adoption and improve building industry standardization by integrating the two previously separate guidance documents. As a result, the 2018 IgCC is now a unifi ed code that emphasizes adoption, ease of use and enforcement for building projects.
