2021 International Green Construction Code
2021 International Green Construction Code presents a whole system approach to the design, construction and operation of buildings. It contains measures that result in better indoor environments, lower impact on natural resources, better neighborhood connections and improved walkability. Its revised format includes ANSI/ASHRAE/USGBC/IES 189.1-2020 (Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings). Provisions allow the seamless coordination with either the IECC or ASHRAE Standard 90.1 for ease of adoption in any jurisdiction.
