Research On Design Strategy Of The Outdoor Space Of Block-style Commercial Complex Based On Thermal Comfort

With the development of the city and society,the block-style commercial complex emerged at the historic moment.It is an emerging type of commercial complex.The block-style commercial complex first appeared in North America.It integrated the shape of the block into the design,turned the public space on the site into a part of the urban space,opened it to the public,created a pleasant external space,integrated into the urban environment,and constructed a rich Vibrant city life block.The high-quality block-type commercial complex external space is not only an extension of the commercial space,but also a supplement to the urban public space,and has certain commercial value and social value.So far,most of the studies on block-type commercial complexes have focused on the architectural form,business model,and spatial connection.Few studies have been conducted on the design of the external space of block-type commercial complexes from the perspective of thermal comfort.Good thermal comfort is one of the important factors influencing the quality of the external space of a block-type commercial complex,which will affect the user's physiology and psychology,and thus affect the vitality of the external space.With the increasing importance of outdoor environment and the advancement of science and technology,many researchers began to engage in research on outdoor thermal comfort.Related studies have shown that the thermal environment of outdoor space will affect the activity level of outdoor space,but different regions will have different laws due to different climates.The livability and vitality of the city are closely related to the quality of the urban outdoor space.In cold cities,due to the impact of cold climate conditions,residents' outdoor activities will also be affected.When designing buildings,it is of great significance for cold cities to include outdoor thermal comfort affected by climatic factors.When studying the external space of a block-type commercial complex based on outdoor thermal comfort,due to the differences in the psychological and physiological characteristics of outdoor activity crowds,combined with the different effects of outdoor microclimate,the thermal sensations and thermal comfort of different types of people in different climate zones There will also be different laws,and the existing outdoor thermal comfort evaluation indexes will also have regional differences.Therefore,this study analyzes the thermal comfort problems of outdoor pedestrians in cold-street block-type commercial complexes,using data analysis and field survey methods to evaluate the outdoor thermal comfort evaluation indicators UTCI and PET,and modify them in accordance with regional differences to correct This is to study the relationship between outdoor pedestrians and outdoor thermal environment in a cold block-style commercialcomplex,which will prepare for the further study of the design of the external space.In addition,through the investigation of the typical block-type commercial complex in the cold area,the characteristics of the external space are summarized,and the design elements that affect the thermal comfort of the external space are analyzed.Then,a typical model is established,and the control variable experiment is conducted through software simulation.The outdoor pedestrian UTCI scale of the commercial complex is used as the evaluation standard to analyze the thermal comfort quality of the external space under different variables,and then based on the outdoor thermal comfort,a design strategy for the external space of the cold block commercial complex is proposed.
