There’s good news afoot for green buildings despite a U.S. housing slump, says Venture Beat, which outlines $12 billion in revenues in the green building industry last year. The figure is estimated to top $42 billion by 2015. What does it mean? The building industry is definitely going green, despite the up-front costs of getting LEED certified. In fact, a report from Frost & Sullivan indicates that soon almost 25% of all new construction in the United States will be LEED registered projects. This increase in LEED certified commercial projects is good news for the American Institute of Architects (AIA), and their goal of carbon neutrality in all new construction by 2030.
