NGBS Green Certifications See Steady Growth

Halfway through 2018, the NGBS Green Certification program is poised to see an increase in the annual number of units certified.

Since the introduction of Home Innovation Research Labs’ NGBS Green Certification program in 2009, close to 150,000 homes and apartments have become NGBS Green Certified. As of August 2018, there were an additional 120,000 homes in-process for certification. As shown in the chart below, the program has shown steady growth year after year; based on strong growth for the first half of 2018, the program is once again on target to see an increase in the annual number of units certified.
