Green code development

This month, the International Code Council (ICC) is publishing Public Version 2.0 of the draft International Green Construction Code (IGCC) for public review. When the final version is published in 2012, it will provide minimum requirements for sustainable construction. Because adoption of IGCC likely will significantly affect the construction industry, I encourage you to be aware of its development.


IGCC is an "overlay code," meaning it is intended to be used with ICC's other model codes, including the International Building Code and International Energy Conservation Code. IGCC is intended to address sustainability requirements for buildings, including building siting, construction and operation.

IGCC will provide minimum levels of sustainability and allow jurisdictions to adopt requirements providing higher levels of sustainability. For example, the draft includes a minimum provision that no less than 35 percent of nonhazardous construction waste be recycled. The jurisdictional requirements allow jurisdictions to select higher levels for recycling—up to 50 or 65 percent—if desired. As a result, jurisdictions that adopt IGCC may have noticeably different compliance levels.
