Research On Wind Environment Simulation Modification Design Strategy Of University Library In Cold Area

The problem of energy consumption has become a hot issue in today's society.With the expansion of university campuses,the university library is an important role in reducing energy consumption as a building with high energy consumption in campus buildings.In this paper,the university library in the cold area is selected as the object of study,and the two cities in the cold area are chosen as the design and the external environment of the university library and the wind environment of the building body are discussed and studied by simulation modification design strategy.This paper is divided into three parts.The first part is the first,the second chapter,belongs to the basic research.The first chapter introduces the research background,the research object and the research status of the wind environment at home and abroad,and defines the related concepts.The second chapter mainly studies from the low energy university library,the meteorological architecture and the simulated revision design,has laid the foundation and the research direction of this article.Through the data analysis of the climatic conditions in the cold area,it is concluded that the time period of April,May,June,September and October is the transition period,which can bring the space comfort through certain passive low energy consumption measures.The second part is the third and the fourth chapter,which is the main research content.The main subject of the third chapter is the simulation modification design strategy of the external environment of the library,from the campus planning macro-level strategy to enter the design site to modify the wind environment conditions,the study of architectural form and site design is carried out from the view of meso level,to obtain a preferred combination of designs.The main subject of the fourth chapter is the simulation modification design strategy of the library building,from the micro-strategy to the adaptive building interface and open reading space to study.Mainly using Fluent CFD simulation software,with a certain climatic conditions as the basis,the university library design process simulation analysis.Finally,the design strategy diagram,in this strategy can be designed to save a certain amount of energy consumption.The third part is the fifth chapter,which is the practical application of the project and the actual measurement.This paper discusses the wind environment of the building and summarizes the corresponding design rules,and makes some suggestions on the revision of the library by discussing the application examples of the simulated and corrective design by investigating the library of Hebi City Vocational and Technical College.Through the above methods,the optimal design strategy of low-energy university library is discussed,and the architectural design model which can achieve the purpose of ventilation and energy saving can be obtained at the initial stage of design.We hope to make useful suggestions for not only the university library,but also the low energy consumption environment design of other public buildings.
