Research On Passive Design Strategy Of Library In Hot Summer And Cold Winter Area

Since the industrial revolution,advances in technology have greatly advanced the development of human material civilization,and at the same time triggered a serious energy and ecological crisis.The development of science and technology has brought great freedom of architectural creation,resulting in an ever-increasing proportion of building energy consumption.In China,building energy consumption accounts for 20.6% of the total national energy consumption,and will continue to increase in the future.Under the influence of the sustainable concept,green buildings,ecological buildings and low-carbon buildings have become the focus of the construction industry.Passive design is an important way to realize green buildings and has great significance for the construction of ecological civilization.Apply passive building design principles and graphical analysis,thsware software simulation and other methods to explore the principles and strategies of ecological library design.Firstly,through the arrangement of the development and status quo of green buildings,the research direction of passive design of libraries in hot summer and cold winter areas is determined.Analyze and summarize the passive theory practice and library development at home and abroad,and lay the theoretical foundation of library passive design.Then it conducts research and analysis on the library of hot summer and cold winter area,and draws the actual foundation of the paper based on its current situation.On the basis of historical research and practical significance,this paper studies the passive design principles and strategies of the climate zone library and guides the corresponding design practice.The passive design principles of the library in the hot summer and cold winter area are mainly integrated sunshade,comfortable lighting,ventilation and wind-proof unity,and thermal insulation and heat management.Passive design strategies mainly include planning,single and detailed construction.Planning layout needs to consider site selection and environment,general layout,building orientation,and landscape design.Site selection should consider accessibility,good ecological landscape,the general plane adopts small depth and deep layout,Dajinshen Library should adopt optimization strategies such as atrium and courtyard,landscape design green plants,water bodies,ecological grounds,etc.to optimize outdoor microclimate;It mainly includes the shape and space design.The shape can expand the lighting surface through the shape cutting,realize the self-shading of the body through the picking and dislocation,strengthen the ventilation through the wrong movement,the inclined roof and the tall structure;the space design passes through the atrium,the threedimensional courtyard and the peripheral buffer.Space and other strategies.The detailed design starts with ecological skin,lighting,shading and ventilation components,and combines climate and functional attributes to optimize passive design.The passive design of the library needs to construct a systematic strategy from all sides,to avoid disadvantages,and to adopt the passive priority and active assistance principle to meet the indoor environment comfort.
