Feng shui in ancient China was harmonized with the natural environment. The layout of houses following feng shui is conducive to a comfortable wind environment. To explore the positive influence of feng shui on ventilation, this study takes Prince Kung’s Mansion, which has the characteristics of a feng shui layout, as the research object. In parallel, the study assumes a dissimilation layout that has lost the feng shui layout characteristics. Comparing the ventilation of courtyards in the summer for both the feng shui layout and the dissimilation layout through CFD simulation, the results were as follows: (1) the wind speed values in the summer, taken from 60 points in Prince Kung’s Mansion by way of CFD simulation and field experiments, were well coupled, which proves that PHOENICS is suitable for the courtyard wind environments simulation in this study. (2) The CFD simulation results show that the average wind speed and the comfortable wind speed zone ratio in the courtyards of the feng shui layout were higher than those of the dissimilation layout during the summer, and the courtyard wind speeds of the two layouts were linearly related. Therefore, the feng shui layout is more conducive to the comfort of courtyards’ wind environment than the dissimilation layout. (3) The front and rear wind pressure differences of the main houses in the feng shui layout can optimize the indoor ventilation better than those of dissimilation layout in the summer. (4) According to the evaluation criteria for the wind environment, the wind speed and wind pressure of the feng shui layout are superior to those of dissimilation layout in the summer. In summary, this study verifies that the layout of feng shui optimizes the courtyard wind environment in the summer, which embodies the ecological concept of the Chinese ancients in the layout of houses.
Since the Western Jin period, Buddhism has confronted bureaucratic power within the architectural landscape. In this study, historical records and archaeological reports of two Buddhist temples—the Siyuan Temple 思遠佛寺 built during the reign of Tuoba Hong 拓跋宏 and Emperor Xiaowen 孝文帝 of the Northern Wei dynasty, and the Zhaoren Temple 昭仁寺, built during the reign of Li Shimin 李世民 and Emperor Taizong 唐太宗 of the Tang dynasty—were examined. A comparison was made of the two temples’ geographic locations in relation to cities while considering period-specific phenomena. This study also considers mountains, water, and topographical features. The geographic information reflects differences in the ideas of the ruling class and monarchs of the two historical periods. The findings are that both Buddhist temples were close to the capital and both emperors demonstrated the supremacy of their power by building them. Therefore, the religious landscape owes its formation, development, and underlying significance to emperors and social groups.
