Ventilation Methods In Guangfu Traditional Dwellings And Applications In Modern Buildings

In the course of traditional dwellings'evolvement, series of simple and effective methods have been formed to accommodate diversified local climates. These methods have been turned into different kinds of regional climate adaptation skills and techniques after continuously adjustments in practial applications. The ventilation of Guangfu traditional dwellings, which lies in hot and humid subtropical climate area, is outstanding in climate adaptability. For purpose to accommodate the hot and humid weather in summer days, diverse ingenious ventilation solutions are applied to remove indoor thermal force and to reduce humidity. Exploring and analyzing the traditional ventilation skills and solutions would be valuable for us to understand and acquire the wisdom of Lingnan traditional ventilation from a new perspective.Guangfu traditional ventilation solutions and techniques are divided into three dimensions to investigate and analyze in this paper. Ventilation and thermal environment of representative models in each dimension have been studied to reach the summarization of ventilation traits and values in Guangfu traditional dwellings. First dimension is the ventilation of traditional dwelling group. Guangfu traditional dwelling groups not only can channel external natural airflow into them, but also can generate internal thermal ventilation to ensure favourable outdoor environment for the dwellings on macroscopic perspective. Second dimension is the ventilation of single traditional dwelling building. Guangfu traditional dwellings are categorized into three basic types and some evolved forms in this paper. The outcome of actual measurement of each typical model reveals that the indoor space and its combinations of Guangfu traditional dwellings are capable to lead the outside airflow inside buildings as well as to engender internal thermal ventilation, as a result to provide the building itself an enjoyable indoor environment. The third dimension is the ventilation of traditional dwellings'detail. Multifarious special ventilation solutions are used in Guangfu traditional dwellings'detail to assure good quality for its actual ventilation on microscopic perspective. The practical effect and the action mechanism of different ventilation technic will be discussed in this paper by means of actual measurement and CFD simulation.Integrated with innovated thinking, traditional effective ventilation ecperience is converted into practical modern designs on the basis of the summarization of traditional ventilation wisdom. Traditional experience is applied into modern ventilation designs in planning desings, single building designs and archictural detail designs. The application effects are analysed through actual measurement and CFD simulation. Approaches to modern renovations of traditional technics and issues to its modern applications are also explored in this paper supporting by quantification data analysis. The outcome of analysis estimates that effective ventilation for thermal force elimination and humidity reduction is continuously demanding in hot and humid climate area. It also manifests that traditional experience of Guangfu ventilation solutions can be adaptable and be use for reference to modern ventilation designs. The compounding of traditional ventilation experience, contemporary techniques, modern materials and structures would provide impactful approaches for modern designs to improve ventilation effects and would achieve modern renovations from traditional ventilation solutions and skills.
