Investigation on Energy Saving Potential of a Vertical Greening System in Hot Summer and Cold Winter Areas in China

As a new type of greening method, vertical greening can not only solve the problems of shrinking green space, poor air quality, reduce the heat island effect on urbanization, but also affect the annual building energy consumption. In this paper, the energy saving potential of vertical greening in China’s hot summer and cold winter regions is investigated through comparative experiments between a vertical greening room and a reference room. During winter, the total power consumption of the reference room is 1.22 times that of the vertical greening room. The energy saving rate of the vertical greening system is concluded to be approximately 18%. During summer, the total power consumption of the reference room is 1.33 times that of the vertical greening room. The energy saving rate of the vertical greening is approximately 25%.
