During the colder season, from November to April, the energy consumptions for cooling under the three defined scenarios are almost the same. A difference of the energy consumption for cooling starts to appear in May when the weather becomes warmer,and it reaches the peak in July. 52.84 GJ of cooling energy was consumed by the building under the scenario 1 (without a green roof).In July, 5.4% of the energy was saved by the green roof (scenario 2),and 8.4% of the energy was saved by the green wall (scenario 3).
