Several years ago, Illinois, the mayor of Chicago, decided to have vegetation（植物） planted on Chicago City Hall after he visited Germany, a leader in green roof（屋顶） design.

Green roofs are designed to save energy and collect rainwater. Roofs covered with plants help keep buildings cool. Earlier in 2008, researchers in Texas reported that green roofs can reduce（减少） a building's air conditioning costs by about one-fifth compared to black-top roofs. Besides, vegetation on roofs help stop water running off into streets and make the life of a roof longer.

Researchers say green roofs usually do not get much above 27, so temperatures might not be a problem for growing. However, green roof gardeners have to be careful not to put too much weight on the roof. This is true whether plants are grown in soil or water.

"Not all green roofs perform well." Mark Simmons, one of the researchers said, "Designs are different in keeping buildings cool and collecting rainwater. They have to be done right." In order to improve green roof conditions, researchers did many experiments. They compared products from different companies to help them understand how to make their designs work better.

Researchers also found some native（本地的） plants such as sedums which need little water. Therefore they can help the green roofs take in more water and help keep buildings cool. Today, the tops of some buildings in America look like farms as well as parks. Rainwater is used to grow lettuce, tomatoes, cucumbers, peppers and many other kinds of plants.
