Study On The Design Strategy Of Rural Residential Buildings In Eastern Henan Under Thermal Comfort Orientation

The construction of rural residential buildings in China has a wide area and a large quantity,and it has maintained a rapid growth for many years.However,With the gradual improvement of rural residents’ requirements on the quality of living environment,the thermal comfort of buildings has drawn more and more attention.How to improve the current low level of the thermal comfort through design has become the main topic of research.Therefore,it is urgent to construct a thermodynamic model suitable for rural residential buildings,especially under specific climate conditions.Starting from the influence factors of thermal comfort,this paper combines the typical cases of rural residential building with the analysis of the rural residential buildings’ thermal and wind environment.And combing the relationship between architecture and environmental elements in the eastern of Henan province,this paper puts forward some strategies that suit for such area,in order to provide new ideas for the research on rural residential design as well as the references for energy efficiency design.The content of this paper can be divided into the following four parts:First of all,focused on the scope of the eastern of Hnenan province,based on the literature review and field survey of the region and combed the development of rural residential building in the region,the study has followed the abstract methods of prototypes and divided these residential building into the traditional courtyard housing concise type,dispersing compound type and compact unit type.On the basis of three types of prototypes,typical cases are selected to analyze thermal comfort and related physical properties.Secondly,this research has introduced the contemporary green building theories.Taking comfort optimization as the goal,environmental regulation system as the framework,and the selection relationship between buildings and environmental climate as the premise,this paper has analyzed the four levels of form space,the organization of function space,the selection of interface and material structure,and completed the construction of thermodynamic model of eastern Henan Province through the qualitative analysis.Thirdly,this research has substituted climate data,family composition,production and living demands of eastern Henan into the thermodynamic model.Based on the quantitative analysis,the optimal design strategy for rural residential buildings is deduced and applied to the scheme design.Finally,on the basis of using the design strategy to complete the scheme design,the study has taken the core house type as an example to calculate the comprehensive performance of the building,and taken thermal comfort optimization as the goal to conduct the balance of wind and thermal environment and energy consumption analysis in order to verify the effectiveness and feasibility of the design strategy.
