Catalyst - Green Roofs
Studies from the Northern Hemisphere show that you can keep the cold out and the heat in by adding a green roof to a building. But in warmer climates vegetation can also cool a building down.
Plants provide shade and another layer of insulation on the roof, which keeps the temperature of the building down. And when it rains, the plants soak it up and later release it through evapotranspiration, which provides a further cooling effect.
