Minneapolis has gone green with more than 80 green rooftops. The Central Library, the Target Center, a handful of underground parking garages and the lawn-bowling green at Brit’s Pub are just a few located in downtown. One of the oldest examples is the Hennepin County Government Center’s north plaza which is a park area above a cafeteria and office space. A 5,800-square foot roof at City Hall includes plantings and solar panels.
