Wisconsin Green Built Home™ (GBH) is an award-winning green building initiative that reviews and certifies new homes and remodeling projects that meet sustainable building and energy standards. The program is implemented in partnership with the Madison Area Builders Association in cooperation with other participating builders associations, leading utilities and organizations that promote green building. GBH, affiliated with the NAHB National Green Building Program, is also available as a co-branded home certification. GBH was the first program east of the Mississippi and between 1999 and 2007 has certified 3,700 homes in Wisconsin, Minnesota and Illinois.
