Target Center, Minneapolis
The roof of the Minnesota Timberwolves’ arena is covered with native prairie plants and grooved with pavers that mimic the veins of a leaf. When it rains, this 2.5-acre topper soaks up nearly a million gallons of water that would otherwise pollute the Mississippi River. The endangered Karner blue butterfly flutters among the lupines.
Brooklyn Grange; Queens, N.Y.
Purportedly the world’s largest rooftop farm grows six stories above the street and offers a grand view of Manhattan. It supplies local restaurants with peppers, eggplants and 40 varieties of tomatoes. This spring, it will double its 40,000-square-foot growing area with a second location in the Brooklyn Navy Yard.
Ford dearborn truck Plant; Dearborn, Mich.
This factory in Ford’s River Rouge complex, just outside Detroit, is carpeted with greenery that reduces heating and cooling demand by 5 percent. The 10.4-acre site was designated the largest industrial green roof on Earth.
Vancouver Convention Centre; Vancouver, British Columbia
Jutting over the waterfront at Coal Harbour, this geometric puzzle is the largest nonindustrial green roof in North America, and it helped the facility become the first convention center to earn a LEED Platinum rating — the highest grade for green buildings.
High Line, New York City
In addition to being the longest green roof in the U.S., Manhattan’s spectacular High Line may also be the nation’s most visited. Each day, thousands walk the 1.45-mile-long former train track that runs through Chelsea and the Meatpacking District. A third and final section of the line awaits rehabilitation.
