What would installing a green roof help with?(choose 2)
A: Increasing off-site renewable energy
B: Eliminating CFCs
C: Reducing heat islands
D: Increasing the lifespan of the roof

参考答案: CD

本题解释:
A green roof does not impact offsite renewable energy.

The choice of refrigerant and if natural or mechanical ventilation is used are decisions that help eliminate CFCs.

Green roofs typically have a longer life-cycle than traditional roofs (according to LEED).

Green roofs help reduce heat islands. They also help provide greater insulation of the roof to reduce energy consumption.

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.
