Abstract

Abstract

Based on the application and development of vertical climbing green facde in high-density cities, the vertical climbing green facades on thermal and wind environment in hot-humid climate areas. Firstly, field measurements were conducted to record the thermal indices around a case of climbing green facade in typical extreme hot summer days in hot-humid climate areas. Secondly, a validation was conducted with a CFD simulation method with the software. Then, the combination condition of typical overhead transition space and climbing green facade was simulated and tested for human thermal comfort evaluation coupled with CFD and Ladybug+Honeybee tools. The results showed that: 1)field measurements results revealed that the temperature, globe temperature (T_g), and wind velocity (V_a) of the shaded area was reduced by 0.06-0.53 ℃, 0.37-1.73 ℃, and 0-0.18 m/s compared to the unshaded area, relpectively. The mean radiant temperature(MRT) and physiological equivalent temperature(PET) were reduced by 0.58-2.74 ℃ and 0.27-1.43 ℃, respectively; 2)CFD simulation results revealed different greening models reduced the average temperature by 0.1-0.3 ℃ except the model FG-1; 3) the wind velocity of model FG-2 and FG-3 reduced by about 1.3 m/s, the wind velocity of DG model series reduced by about 0.8 m/s; 4) the PET of FG-2, FG-3, DG series and WG series models reduced by about 0.8-1.1 ℃. Furthermore, FG-2, FG-3 and DG series model presented better optimizations on the whole open floor space and could be the better choice for the greenery layout.
