Study On The Space Design Of Exhibition Building In Cold Region Based On Energy Consumption Analysis

In recent years,with the recovery of the world economy,the global exhibition industry has shown an all-round,diversified and stable development trend.Among them,China's exhibition industry has developed rapidly,the number of exhibitions has steadily increased,and the rapid growth of scale has shown a good momentum.All regions have great demand for exhibition buildings.In order to maintain the comfort in the high space of the exhibition hall,the energy consumption of the building is particularly large,but at the same time the energy saving potential is also great.Among them,architectural form is an important factor affecting building energy consumption.In the context of the increasing amount of space in the exhibition halls,the energy conservation from the form of the building and the design stage is considered to be of great significance to the design of the space of the exhibition hall.Especially in the cold regions of China,the problem of huge energy consumption needs to be solved urgently.In this context,this paper starts from the two aspects of the monolithic design and group composition of the exhibition and exhibition space in the severe cold area,and studies the quantitative relationship between them and the building energy consumption,and draws the corresponding relational expression.According to the field survey and research and literature review,the typical shape design parameter matrix of the single space and group combination configuration of the exhibition building exhibition hall in the severe cold area is established,and the energy consumption experiment model is established,which is in the monolithic design and group combination configuration of the exhibition hall space.The typical elements are simulated and analyzed,and the quantitative relationship between each typical factor and building energy consumption is obtained.A multi-regression model is proposed to study the spatial shape design method of the exhibition building exhibition hall under the low energy consumption target.This paper analyzes and summarizes the design status of the exhibition hall single and exhibition hall group configuration in the cold and cold area,and collects the geometric parameters of the exhibition hall exhibition space through field research and literature review.The main exhibition items are classified into the process morphology parameters based on the exhibition process.The intersection of the two forms the typical shape data set of the exhibition hall.Using 3D drawing software Rhino to create the exhibition hall model and import it into Grasshopper,establish the relevant parameters of the exhibition hall variable in Grasshopper,call Energyplus with Honeybee,face length,depth length,plane aspect ratio,height,roof of exhibition hall space The energy consumption simulation is carried out by the proportion of the skylight,the proportion of the facade window and the combination of the group exhibition hall.Then,the data was analyzed by Matlab,and the data was subjected to regression fitting to obtain the quantitative relationship between each morphological element and energy consumption.Finally,the regression analysis is carried out on all the parameter variables in the experiment,and the multiple regression equations of the exhibition space width length,depth length,plane aspect ratio,height,roof skylight ratio,facade window wall ratio and building energy consumption are obtained and sensitive.Degree analysis,and finally the energy-saving design process of the exhibition space of the exhibition building in the severe cold area.Studying the quantitative relationship between the various parameters of the single space of the exhibition and exhibition building in the severe cold area and the energy consumption of the building and the qualitative analysis of the building composition and building energy consumption,it can quickly calculate the corresponding building energy consumption in the architectural design.Conducive to the energy-saving design of the exhibition hall exhibition space,and through the multi-regression fitting equation and the application of the best shape parameter group,the building energy consumption can be compared efficiently,the energy-saving effect of the exhibition space of the exhibition building in the severe cold area can be quickly judged,and the shape design can be modified in time.Data to achieve energy-saving design.
