Public Comments Reviewed for ICC 700-2020 National Green Building Standard

The 45-member Consensus Committee for the ICC 700 National Green Building Standard (NGBS) met Feb. 11-13 in Washington, D.C., to review and vote upon the public comments it received to its 2020 draft standard.

The draft standard includes several substantial updates, including:

  • a complete reworking of the Remodeling chapter,
  • a new chapter for certifying mixed-use buildings (that are at least 51% residential (gross floor area)),
  • a new performance path for Water Efficiency, and
  • a streamlined compliance path for single-family homes and townhomes.

During the meeting, 328 public comments were dispositioned. Of those comments, 44% were approved or approved with modifications, while 55% were disapproved, and 1% were withdrawn.

The 2020 NGBS will be the fourth edition of the standard, which was first introduced in 2008. NGBS is the only residential green building standard that is American National Standards Institute (ANSI) accredited, and once again, the standard is being developed in accordance with the ANSI consensus process.

Next steps involve a concurrent committee ballot and public comment period on the Second Draft Standard, expected to take place from March to May 2019, followed by review of new comments by task groups and the committee. Submission to and approval by ANSI will complete the process.

With the anticipated launch of the new edition in first quarter 2020, Home Innovation Research Labs is starting the development of the certification tools and resources for 2020 NGBS certification. The goal will be to allow projects to register for 2020 NGBS Green certification immediately after ANSI approval.

To date, more than 165,000 homes and apartments have earned NGBS Green certification, and the program continues to grow at a healthy pace, with an additional 120,000 housing units currently in process for certification. Certifications to date have been primarily for multifamily dwellings (91%), with the highest levels of NGBS multifamily certification in Texas, Florida and North Carolina. A streamlined compliance path for single-family homes and townhomes in the 2020 standard aims to incentivize certification for more of these types of projects.
