McGraw-Hill Construction’s Green Outlook 2011 report estimated that the U.S. non-residential green buildings market in 2010 rose to $43 billion at the low-end, or as much as $54 billion.
The trend should continue over the next five years, the report said, in part driven by public policy and law. As of September 2010, 12 federal agencies, 33 states and 384 local government programs put green building legislation or policies in place, requiring institutional buildings, like schools and court houses, to be green.
