The International Code Council—America’s foremost building code writing body—has released the International Green Construction Code™ (IGCC). The IGCC will provides state and local governments with a “model code” to enforce energy usage and carbon footprint limits with regard to commercial buildings. The code is designed to minimize adverse impacts building construction and operations often have on the environment. The release of the IGCC is a first step in a long process: States generally must authorize adoption of the IGCC in order for it to be utilized or enforced by local governments. That the IGCC is integrated with the other ICC codes that state and local governments already have in place, as well as the flexibility of local officials to customize IGCC provisions to a jurisdiction’s particular climate, should bode well for its implementation.
So what does the IGCC provide?
Baseline Green RequirementsThe IgCC creates a regulatory framework for new and existing buildings, establishing minimum green requirements for buildings and complementing voluntary rating systems which may extend beyond the customizable baseline of the IgCC. The code acts as an overlay to the existing set of International Codes, including provisions of the International Energy Conservation Code and ICC-700, the National Green Building Standard, and incorporates ASHRAE Standard 189.1 as an alternate path to compliance.
Economic BenefitsGreen construction creates jobs and contributes to economic growth according, according to the U.S. Green Building Council Green Jobs Study. In addition, there is no significant difference in the average life cycle cost for green buildings as compared to non-green buildings, according to research by the global construction consultants firm Davis Langdon.
