I want one...sigh...maybe my next home. Green roofs are a solid solution to help combat the problems created by "concrete jungles". From the page: "Cities worldwide are promoting environmentally "green" roofs to mitigate several urban problems. Ground cover, shrubs and other flora planted across a building's roof can reduce storm water runoff, easing the burden on local sewers and water treatment systems. And the vegetation can keep the roof cooler in summer, lowering interior air-conditioning costs and therefore peak demand on area power plants.
Green roofs have been blossoming in Europe for more than a decade, and Tokyo now requires that at least 20 percent of any new roof on medium and large buildings be cultivated. Chicago is the U.S. leader."
