Research On The Design Strategy Of Building Composite Interface Based On Space Thermal Buffer Effect

The climate in hot-summer and cold-winter area is changeable,Extreme weather conditions are very prone to occur in winter and summer.Therefore,Improving the climate adaptability and buffer capacity of building envelopes is an important way to respond to this natural situation.From this perspective,the author used the ecological research of“composite interface” as an entry point to explore the coping strategies of this problem.Firstly,the author summarizes the definition of composite interface and the principle and technical points of thermal buffering effect,and systematically summarizes the mechanism and method of thermal buffering of composite interface from four aspects by analyzing and arranging the research data of predecessors: The spatial level of the interface,the thermal buffer performance,the ventilation path,and the seasonal adjustment mode.Then,the author comprehensively combs the types of composite interfaces,and classifies the composite roofs and composite facades from the form and material.The fourth and fifth chapters of this paper are the computer simulation part,and the thermal environment and hot-pressure ventilation simulation are performed for each composite interface type.The fourth chapter uses DeST software to simulate the different types of composite interfaces and the indoor thermal environment when the composite interfaces are connected to the underground in the natural state of winter and summer.The factors affecting the thermal buffering effect of composite roof and composite facade are discussed.Finally,An ecological energy-saving strategy for composite interfaces is proposed.In the fifth chapter,firstly,the author uses Airpak software to establish a composite interface of different ventilation paths and body types,simulates the hot-pressure ventilation effect in May,and obtains the relationship between the ventilation effect of the composite interface and the ventilation path and body type.Then,the composite fa?ade is connected with the underground space to simulate the influence of the underground cold heat source on the hot ventilating of the composite fa?ade.The sixth chapter is the application strategy research of composite interface in architectural design.Based on the research results of Chapters 3,4 and 5,The author elaborates the application strategy of composite interface in architectural design from the choice of composite interface,the integration of composite interface and functional space,and illustrates the application strategy of the composite interface in the architectural design.Through the regular conclusions and practical application strategies of the composite interface obtained from the above research,it is hoped that it can provide new ideas and reference value for the energy-saving design of building envelopes.
