WASHINGTON — The National Association of Home Builders announced it will end certifications under its Model Green Home Building Guidelines, making way for the ANSI National Green Building Standard to be the lone rating system certified by the NAHB Research Center, according to EcoHome magazine. The Guidelines, introduced in 2005, were the basis for the Standard, which was approved by ANSI in January 2009.
The online Green Scoring Tool will not accept new projects under the Guidelines after April 1. Rough inspections for the Guidelines must be submitted by June 1, and final inspections must be submitted by Sept. 1. Appeals for an extension on the final inspection deadline due to extenuating circumstances must be submitted by Aug. 1.
Developments with multiple houses undergoing certification can continue certification through that phase’s completion or until Dec. 31, 2011, whichever comes first; however, at least one home in the current phase must be certified by June 1 of this year, and builders seeking to be grandfathered must notify the NAHB Research Center by May 1, 2010.
The National Green Building Standard, a joint effort by the NAHB and the ICC, expanded on the original NAHB Model Green Home Building Guidelines and is seen as the more stringent of the two. The move to a single program should ease any lingering confusion between the two systems.
