ZERO GREEN?

Number of green roofs on City, County, State owned buildings                         in Tallahassee:  ZERO

Chicago response to increasing high temperatures in their city is a plan to add 
 . . .green space and vegetation wherever they can, which has a natural cooling effect.
Chicago's City Hall, for example, contains a spectacular rooftop garden. From native woodland grasses to sunflowers and asters, plants arranged in radiating bands of color bloom throughout the seasons in a sunburst pattern. The roof, 12 stories high, contains 23,000 square feet of more than 100 plant species.
"It's really the Rolls-Royce of green roofs." said Michael Berkshire who administers green projects for the city. Some areas of the roof have rolling terrain with an added 18-inch layer of soil to support trees and shrubs. A rainwater collection system irrigates the roof and several bee hives pollinate the many flower varieties.
If every rooftop in Chicago was covered with a green roof, the city could save $100 million in energy every year.

From the PBS series, Coping with Climate Change, which broadcast in October 2012, the full report is here.
