试卷: LEED GA模拟题E[查看] Which of the following does not help achieve a water-efficient landscape?
A: Adaptive plantings B: Replacing perennials with native plants C: Overhead sprinklers D: Installing hardscapes 参考答案: C
本题解释: Adaptive plants are non-native plants that perform well in the local climate. Native and adaptive plants require less water, and are more disease resistant because they are suited to the region\'s usual rainfall, soil, and temperature.
Perennials usually require more water.
Overhead sprinklers contribute to runoff and evaporation by wind and sun.
Hardscapes can increase the heat island effect and stormwater runoff, but they do reduce the size of the area that needs irrigation. |
