How can the heat island effect on the roof of a building be reduced?


A: Painting the roof with a high SRI coating
B: Increasing the amount of roof insulation
C: Covering the roof with recycled materials
D: Providing underground parking

参考答案: A

本题解释:
Heat islands on a roof can be reduced by reducing the amount of area that is dark, either through solar panels or a green roof, or painting exposed areas with light colored materials. A material with an SRI of 100 is light colored.

The heat island effect is created when developed areas have higher temperatures than surrounding rural areas. An urban heat island effect is caused by sunlight heating up dark colored surfaces such as roads and rooftops. Huge quantities of heat are generated in buildings that have dark rooftops and absorb heat rather than reflect it.
