The 86,000-square-foot Grand River Center in Dubuque, Iowa, located on the Mississippi River, hosts an annual sustainable communities conference, aimed at connecting local governments with populations of less than 200,000 with best practices in sustainable development.
Part of the America's River redevelopment project at the Port of Dubuque, the center boasts several sustainable features of its own. The 10-year-old building uses natural light to minimize energy needs, and features permanent recycling bins and automatically controlled restroom facilities. The center continues to add sustainable features as new technologies become available, including smart meters that track utility usage trends. Located on a trolley route with plenty of bike racks, center visitors are encouraged to leave their cars at home.
