Research On The Microclimate Optimization Of The Exterior Space Of A Block-type Commercial Complex Based On Numerical Simulation

The external space of the block-type commercial complex is the characteristic space of this kind of building,and its existence makes it have a more pleasant scale and more intimate experience than the traditional commercial complex,which makes the occurrence of behavior rich in possibility.Because the outer space of block-type commercial complex is directly connected with the city,it has also become an important part of urban outdoor space,so the microclimate state of its external space is not only affected by its own space design.at the same time,it is also affected by the urban microclimate of the region.The external space microclimate environment in Jinan area is obviously affected by seasonality,and people’s outdoor behavior is affected by microclimate to a great extent.through the subsequent investigation and statistics of this paper,it is found that the building form of block-type commercial complex in Jinan area has its rationality and necessity.Therefore,improving the microclimate state of the outer space of the block-type commercial complex is of great significance to enhance the vitality of the block-type commercial complex.Therefore,this paper takes the outer space of the block-type commercial complex in Jinan area as the research object to explore the relationship between crowd behavior and microclimate,in order to put forward suggestions for the optimal design of the outer space of the block-type commercial complex in Jinan area.The full paper is divided into five parts,the first and second chapters are the basic research parts.Firstly,through background research and literature review,explain and define the related concepts of microclimate and block-type commercial complexes involved in the research,and understand the current research status at home and abroad;then trace the source of block-type commercial complexes and compare them vertically and horizontally to illustrate the research The importance of external space research;the last is the interpretation of microclimate and comfort related theories and evaluations,which provide a research background for the research and analysis of chapters three and four.The third chapter is the statistics and analysis of comfort questionnaire and microclimate measurement.Firstly,determine the microclimate factors that affect comfort through the method of comfort questionnaire survey and user behavior observation;then use the method of fixed-point measurement to find out the microclimate problems existing in the external space of the block-type commercial complex,and analyze the space that may affect the microclimate.The element makes a preliminary judgment.The fourth chapter is about numerical simulation and determination of influencing factors.It is divided into two aspects: one is to construct a simplified model for numerical simulation of the current situation of the external space of Kuanhouli in Jinan,and to find the existing microclimate problems in the external space of Kuanhouli;The horizontal and vertical comparisons of comprehensive numerical simulation experiment results provide an in-depth analysis of the causes of microclimate differences in various spaces,and provide a reference for subsequent external space microclimate optimization.The fifth chapter is the suggestions for the optimization of the outer space of the block-type commercial complex.Aiming at the planning and construction of block-type commercial complex in Jinan area,optimization suggestions are put forward and verified by numerical simulation from the aspects of road space layout,square space setting,building form design,site setting and so on.
