Comparative Study On Core Traffic Space Model Of Commercial Complex In Hot And Humid Area Based On Human Thermal Comfort

With the development of society and the improvement of people's material living standards,commercial complex buildings have developed rapidly in recent years,and are more and more popular,becoming an important place for people's daily leisure,shopping and entertainment.Due to the particularity of climate and environment,the hot and long summer,the development mode of commercial complex buildings in this area is different from that in the north,which is mainly reflected in the diversity of the core traffic space mode of commercial complex.In addition to the traditional totally closed commercial complex,it also includes semi closed and decentralized commercial complex types,different types of commercial complex The core traffic space thermal environment characteristics of the complex are also different,and good space thermal environment quality is particularly important for people's physical and mental health.Therefore,how to optimize the space thermal environment level of commercial complex and improve the space thermal comfort has gradually become the focus of attention.In view of the above problems,the first part of this paper,based on the thermal comfort level of human body and the climate characteristics of hot and humid areas,selects three typical commercial complexes of core traffic space model in Guangzhou: totally enclosed(Taiguhui),semi enclosed(Dongfang Baotai)and decentralized(Tianhuan Square)as the research objects,and respectively conducts research on them in summer,transition season and winter Based on the investigation and research of the current situation of thermal environment and thermal comfort of human body,and the statistical and linear regression of the investigation data,the thermal comfort models of three commercial complexes with typical core traffic space mode are established respectively,and the differences among the three models are found out by comparing their respective physical parameters of thermal environment,thermal neutral temperature,comfort temperature range and typical daily comfort duration On.The second part of this paper is the theoretical regression design.Firstly,the software optimization simulation of the thermal environment of the core traffic space in each season is carried out for the decentralized commercial complex,and the thermal comfort of the space is optimized by increasing the local sun shading of the top interface;secondly,the theoretical analysis method is adopted for the semi closed commercial complex,and the suggestions for the optimal design of the thermal environment of the core traffic space are put forward;finally Based on the conclusion of the optimization design,this paper puts forward the motif of the core traffic space mode of courtyard type roof added interface partial shading,and based on this motif,puts forward the design strategy for the core traffic space mode of commercial complex in hot and humid areas.
