Since the introduction of our NGBS Green Certification program in 2009, close to 150,000 homes and apartments have become certified. As of August 2018, there were an additional 120,000 homes in-process for certification. 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.
According to data from Home Innovation’s 2018 Annual Builder Practices Survey, more new homes are getting side & rear porches and decks than in past years, but fewer are getting on-grade patios. The inclusion of front porches and stoops on new homes, however, has fairly stable over the past decade.
Concrete homes are not new, and in a lot of places throughout the world they wouldn’t be described as particularly “fashionable” or trendy. There is concrete in nearly every home in the United States, particularly at the ground level and below, while above-grade portions of most residential structures are built primarily with structural wood framing. Less than 10% of new U.S. homes are constructed with above-ground concrete walls, and that hasn’t changed much over the past few decades though there has been a bit of ebb and flow.
