Which of the following do not contribute to increasing the heat island effect in urban areas?(choose 2)
A: Open grid pavement
B: Bioretention ponds
C: Absorption of heat by hardscapes and its radiation to surrounding areas
D: Vehicle exhaust

参考答案: AB

本题解释:
Open grid pavement is a strategy LEED accepts to reduce heat islands. Open grid pavement has cells in it to allow vegetation to grow.

Bio-retention ponds are landscape features that help control rainwater runoff. They are commonly called rain gardens.

LEED does not consider any type of water body or landscape feature as something that contributes to the heat island effect.

The primary cause of the heat island effect is dark surfaces such as rooftops or dark asphalt pavement that absorb heat and radiate it into the surrounding areas.

Other causes of the heat island effect include air-conditioners, vehicle exhaust, and calm and sunny weather.

Reduced air flow between buildings and narrow streets increases the effect.
