The National Association of Home Builders (NAHB) and the International Code Council (ICC) said they applauded the recent approval of the 2012 ICC 700 National Green Building Standard.

"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, FL. "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."

The original standard was developed in 2007 by NAHB and ICC. The ICC 700 National Green Building Standard was the first and remains the only residential green building rating system to undergo the full consensus process and receive approval from the American National Standards Institute (ANSI). This is the first time the standard has undergone Consensus Committee review and update since it was published in 2009.

Among the changes included in the new version of the standard is an Energy Code Update. The original ICC 700 used the 2006 version of the International Energy Conservation Code (IECC) as a basis. The new standard will use the 2009 IECC, with an estimated 15% energy efficiency improvement.

The new standard also changes scoring for renovations and remodeling projects. One chapter of the revised standard provides criteria for entire buildings, including requirements for better energy and water efficiency. Another chapter provides a green protocol for the most common renovation and addition projects: kitchen, bathroom, basement, or addition under 400 square feet.

The 2012 ICC 700 also adds a new scoring opportunity for those choosing to build on lots in green communities.
