Study On Passive Regulation Strategy Of Indoor Thermal Environment Of Stone Houses In Cold Areas Of Sichuan

The stone dwellings in the cold regions of Sichuan are an important carrier of traditional architectural culture and heritage in China,and an important part of rural architecture in western Sichuan.It not only contains rich experience in ecological construction,but also reflects Tibetan and Qiang national culture.Historically,stone-built residential buildings have been widely distributed and widely distributed in the cold regions of Sichuan.They have a certain effect on the active local culture and economy.With the improvement of China's economic level,people's requirements for living conditions have increased,and the indoor thermal environment of traditional houses has been unable to meet people's living needs.Therefore,the study of stone-built dwellings in the cold regions of Sichuan is of great significance to promoting the sustainable development of traditional dwellings in China,improving the indoor thermal environment and improving the quality of the living environment.The thesis uses literature research,field investigation,questionnaires and computer simulation to systematically analyze the problems existing in the indoor thermal environment,screen the passive transformation technology suitable for local stone houses,and finally quantitatively evaluate the transformation effect through computer simulation software.Feasibility of the transformation strategy.In the survey,the questionnaire was distributed to test the physical environment of the local stone buildings,to understand the indoor thermal environment and the residents' demand for thermal comfort,and to find out the problems of the indoor thermal environment.In addition,based on meteorological data,the human thermal comfort is used as an evaluation index.Under the premise of finding the effectiveness of passive control factors,the effectiveness of the overall passive strategy of residential buildings in typical cities of cold regions in Sichuan is evaluated by computer software.;Analysis of individual measures of passive strategy.On the basis of qualitative analysis,a suitable passive regulation method is proposed.Finally,use Designbuilder to simulate verification and analysis.It can be seen that the indoor temperature is more stable throughout the day after the renovation,the indoor temperature maximum is increased by 4.4 ?,the average value is increased by 3.85 ?;the south to the bedroom thermal comfort hours increased by 58%;the north to bedroom thermal comfort hours increased by 41% The living room thermal comfort hours increased by 36%.The passive regulation strategy proposed in this paper and the related achievements are expected to provide reference and basis for improving the indoor thermal environment of stone houses in cold regions of Sichuan.
