Home Innovation Research Labs Recognizes 2023 NGBS Green Partners of Excellence

Home Innovation is proud to recognize 66 NGBS Green Partners for their outstanding contributions to advancing green building in their communities. These individuals and businesses have been awarded the Partner of Excellence title as a testament to their commitment to voluntary, above-code, third-party certification of high-performance homes to the ICC 700 National Green Building Standard (NGBS). 

The NGBS Green program has certified over half a million homes – more than any other residential green certification program in the United States. Dedicated efforts from all of our partners, and especially those recognized below, have driven the program’s momentum over the years. This group represents the incredible diversity of home designs certified by the program, including those from affordable to luxury, student to assisted living, single family to high-rise apartments, and everything in between. While each home is sustainable and high-performing, many have been developed with zero energy or net zero water use, resilient construction, and wellness-focused features. 

Partners of Excellence are recognized in several categories: Multifamily Builders & Developers, Single Family Builders & Developers, Verifiers, and Industry Advocates. Legacy (**) recipients have been awarded for 5 or more consecutive years and Rising Star (*) recipients are being awarded for the first time. Criteria for recognition include certification volume, advocacy, commitment to quality, and contributions to the program.
