“…Compared to wind tunnel experiments, CFD can better render the complex flow field phenomena. CFD has been used to assist building and urban design in England, Japan, and the USA (Tang et al, 2012). It can provide designers with accurate parameters and help them to plan urban and residential areas scientifically, which can reduce the impact of new designs on the surrounding environment and the use of energy in the future (e.g., Yuan and Ng, 2013; Hsieh et al, 2011).…”

“…Only Tang et al (2012Tang et al ( , 2014) simulated a Chinese historical community using a simple current 3D terrain model, and investigated the influence of terrain on historical settlement in two separate chapters, i.e., the CFD wind environment and thermal environment. In their research, only the current status was simulated, with no simulation of the past for the historical community.…”

During the initial developmental stage of historical settlement, residents used the principles of feng shui to locate suitable residence sites to ensure quality of life. Using Huazhai Village in Taiwan as a case study, this study explores the design philosophy of ancient Chinese people through scientific analysis. Research showed that the region was characterized by a windy climate. Therefore, a computational fluid dynamics model was used to simulate the local wind environment and restore the early architectural complex of the village. Compared to the current situation, it was demonstrated that the planning principles of the early buildings gave first priority to site selection. Second, with the village streets acting as a wind corridor, the angle of the streets was well utilized to strengthen outdoor ventilation in summer. Third, according to wind field characteristics at different locations, various opening directions and arrangement modes were applied in different areas to improve the wind field of the living environment. This ancient ecological wisdom provides current designers with a new strategy for living in harmony with nature, which may aid the design of sustainable living environments that adapt to the climate.

a b s t r a c tIn recent years, energy efficiency and thermal comfort in historic buildings have become high-interest topics among scholars. Research has demonstrated that retrofitting buildings to current energy efficiency and thermal comfort standards is essential for improving sustainability and energy performance and for maintaining built heritage of historic structures. This study is an extensive overview of the literature surrounding this topic. This paper summarizes the different methods and techniques that have been used around the world to achieve performance refurbishments. Articles are organized based on the different building types used as case studies (residential, religious, academic and palace, museums, libraries and theaters, urban areas, and others). The results reveal that residential, religious and museum building types, especially from the last two centuries, have been most often used as case studies. Moreover, Europe, particularly Italy, is leading the research. The aim of this note is to demonstrate the feasibility of maintaining built heritage values of historic buildings while achieving significant improvements in their energy efficiency and thermal comfort.

“…Their study provides a reference for assessing pedestrian wind environment in the urban planning and design phases. Li Tang [16] studied the wind environment of historical settlements in China by using the CFD method. This researcher evaluated the construction experience of a village in site selection, layout, and landscape adaptation to wind environment, but did not study the impact of building density on village wind environment.…”

With the rapid urbanization and expansion of construction demands in China, the continuously increasing density of residential buildings has led to outdoor pedestrian discomfort in residential wind environment. To analyze the relationship between residential building density and wind environment, simulation cases of residential buildings with different building densities were presented in this study. First, the wind environment characteristics of residential districts with different building densities were established via computer numerical simulation. Second, wind speed ratio (WSR) and age of air (AA) distribution were calculated at pedestrian height. Finally, the quantitative relationship between residential outdoor wind environment and building density was proposed. Results demonstrate a negative linear correlation between the building density and outdoor mean wind speed ratio (MWSR) of residential districts and a positive linear relationship between building density and mean age of air (MAA). When residential building density increased from 0.18 to 0.32, the MWSR in the district decreased by 0.18, whereas MAA increased by 58.63 s. As residential building density increases, the WSR within the residential district decreases and the age of air (AA) increases, which affect the outdoor comfort of residents. This study provides references for improving the wind environment of high-density residential districts and for optimizing residential layout planning.
