This study focused on greening designs for building openings. Field experimentation was conducted and Computational Fluid Dynamics (CFD) software was used for simulation in order to analyze the influence of different greening design modes on indoor temperature. A greening design mode suitable for the opening of houses in Kaohsiung was proposed. This study took an architectural space with a pitched roof as the experimental site, where the main variable was the location of the plant facade outside the opening, and the distance between the plant and wall surface, as well as the number of plant layers, was the control variable. A plant (Rose of China) was selected for experimentation, and the indoor temperature distributions under various research module settings were discussed by numerical simulation. The conclusions are described, as follows: (1) The air temperature would be affected by the plants, and the indoor air temperature is reduced (over 0.5°C without direct sunshine in this study). (The difference between the indoor cooling effects with and without plants was 0.89~1.11°C. (2) While the cooling effect of the double-layer plant on indoor air temperature was better than a single-layer plant, the difference was limited and not proportional. (3) The plants should be located as close to the opening as possible, and be arranged partially sparse and partially dense. (4) When the outside wind speed is low, plant greening is highly recommended for cooling.
