Surprise! Michigan is ranked in the top 13 states for energy-efficient buildings. The list of organizations, foundations and educational institutions promoting a greener Mitten State seems to grow by the day and Washtenaw County is a vital part of that equation. From LEED buildings to the solar panel intiatives on Ann Arbor's Farmer's Market and Ypsilanti's city hall to Greenhills School's rooftop wind turbine, to A3C's state-of-the-art 'green' renovation in the heart of downtown, the Ann Arbor area is tightening its green belt and looking healthier for it.
