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.
MALL OF AMERICA
> There is no heating system in the mall; it relies on the heat from lighting, skylights and the masses of people. It is 70 degrees Fahrenheit 365 days a year.
> Leftover food from restaurants is picked up daily by a local hog farmer.
> The ballpark is the second LEED-Silver-certified Major League Baseball field in the country.
> The nearby Hennepin Energy Recovery Center (HERC) provides heat for the ballpark with captured waste energy. > Nearly 20 percent of Target Field was built with recycled content.
GOLD MEDAL PARK
> Gold Medal Park encompasses 7.5 acres in the heart of Minneapolis’ Riverfront Mill District. The park includes close to 300 mature trees, all hand-picked and between 6 and 12 feet in diameter. The species include maples, lindens, hackberries, oaks and catalpas.
MINNEAPOLIS CENTRAL LIBRARY
> The 18,560-square-foot green roof atop the Minneapolis Central Library creates a model for other downtown buildings and developments and promotes a clean, sustainable city.
> Low-growing prairie plants reduce cooling and heating loads and improves downtown air quality.
MINNEAPOLIS CONVENTION CENTER
> HVAC and lighting systems are monitored around the clock to save energy.
> 2,623 rooftop solar panels produce 750,000 kWh of renewable electricity per year, offsetting 539 metric tons of carbon dioxide emissions annually. > 40 tons per month of material (cardboard, cans, glass and plastic) are recycled. > About nine tons of excess food is donated to local charities in addition to roughly 116 tons of food waste to the food-to-hogs program.
