| Popis: | Vertical gardens have become important strategies for urban heat island migration in recent years. However, the simulation tools for green façade (GF) with climbing plants coupling the shading and wind-induced effects are still lacked. This study focused on GF effects on human thermal comfort (HTC) optimization in a transitional space. The main purpose was to develop a couple method on HTC simulations. Field measurements in a hot-humid climate area were conducted to obtain the parameters of GF foliage layers. A couple simulation method with Ansys Fluent, Ladybug, and Honeybee tools was developed. Seven GFs layouts on a standard balcony model were simulated. In field measurements, the Ave. global irradiation was reduced by 73.29%, leaf area index was measured at 1.56–3.61, and foliage cover ratio was measured at 49.74–92.88%. In the simulations, the results of the Ave. wind velocity were reduced by 0.20–0.77 m s−1, the Ave. air temperature was reduced by 0.2°C, the Ave. mean radiant temperature was reduced by 0.5–7°C, and the Ave. physiological equivalent temperature was reduced by 0.3–3.2°C. The couple method could support the architectural and landscape design integrating with the GFs in future. |
