As most professionals in the A/E/C industry know, while the LEED rating system promoted by the USGBC is the most famous, it isn’t the only third-party green building standard. Due for a major revision in 2012, adoption of the next version of LEED has been postponed while some controversial aspects can be resolved.
In the meantime, the National Association of Home Builders (NAHB) was successful in a 2012 revision to its green building standard for residential construction: the ICC 700 National Green Building Standard. As a bonus, the consensus-based standard has been approved by the American National Standards Institute (ANSI).
“The introduction of the 2012 National Green Building Standard is a huge deal for our industry,” said NAHB Chairman Barry Rutenberg, a home builder from Gainesville, Fla. “Not only does the updated version raise the bar on energy efficiency requirements, but it also completely revolutionizes how renovations and remodeling projects are treated under the standard. The 2012 updates make the standard easier to understand and implement, and we expect that this will certainly help to build upon the momentum we are already seeing in green building across the residential building industry.”
To date, the standard has been widely implemented throughout the industry. The NAHB Research Center, which serves as the secretariat of the standard as it progresses through ANSI, has certified the compliance of thousands of dwelling units and developed lots to the ICC 700. Dozens of regional and local green initiatives refer to the standard within their program criteria. The International Green Construction Code (IgCC) requires compliance with the ICC 700 if a jurisdiction chooses to regulate residential buildings four stories or less in height, except that Group R-1 residential occupancies of all heights are always required to comply with the IgCC.
