ICC 700 National Green Building Standard™

The ICC/ASHRAE 700-2015 National Green Building Standard™ (NGBS) is the first residential green building standard to undergo the full consensus process and receive approval from the American National Standards Institute (ANSI).

First developed in 2008, NAHB, the International Code Council (ICC) and ASHRAE partnered to develop the third edition of the nationally recognized standard, which was approved and published in 2016. Development of the 2018 version of the NGBS is underway, and it is expected to approved and published in 2019.

To date, the standard has been widely implemented throughout the industry. The Home Innovation Research Labs has certified the compliance of more than 100,000 dwelling units. Dozens of regional and local green initiatives refer to the standard within their program criteria and the International Green Construction Code (IgCC) allows the NGBS as an alternate compliance path for residential buildings more than four stories in height. The IgCC refers to the NGBS for all residential buildings four stories or less in height.
