As shown in Fig. 6, the energy consumption for heating in Scenario 1 is slightly higher than the other scenarios. However, this value doesn’t have an obvious decrement with the impact of green vegetation. In the warmer season, from April to October, whereheating is not a functional requirement for the building comfort,the energy consumption values of the 3 scenarios are almost thesame. The highest difference appears in December and Januarywhere 275.98 and 292.24 GJ energy were consumed respectively. Inthe same months, 0.6 and 2.1% of the average energy savings wereachieved by fully covering the roof and walls with green vegetationrespectively
