Green roofs or living roofs are different types of gardens that are created on the tops of buildings to help manage stormwater, improve air quality, help cool city temperatures, insulate the building, create park space, support local wildlife, and much more. New York City’s largest green roof and the country’s second largest—the largest is located on Dearborn, Michigan’s the Ford Rouge Factory—is located on the six block long Javits Convention Center. Their 2014 installation adds 6.75 acres of green space to Manhattan.
NPR visits the Javits roof top to find out how it’s improved the neighborhood and how it’s saved the company three million dollars. Then NPR imagines what a city full of green roofs could be like.
