Research On The Optimization Strategy Of Solar Thermal Performance Of Existing Building Atriums In Universities In Cold Regions ——Taking The Typical Atrium Of Shandong Jianzhu University As An Example

With the enhancement of people’s awareness of energy conservation and emission reduction and the improvement of the quality of life requirements,problems such as high energy consumption in the atrium of existing buildings and uncomfortable light and heat environment cannot be ignored.College buildings are generally built earlier,and the atrium space is often used as a transportation space,and often assumes the auxiliary function of teaching.Due to the strong seasonality in cold areas,the problem of the solar thermal environment in the atrium is more prominent in winter and summer,and the teaching auxiliary function of the atrium is difficult to achieve.,resulting in a larger waste of space.It has certain theoretical value and practical significance to analyze the atrium problem in colleges and universities and establish a model for simulation optimization.This paper takes the solar thermal environment and energy consumption level of the existing building atriums of colleges and universities in cold regions as the research object,sorts out the current solar thermal environment evaluation standards at home and abroad,sorts out the current evaluation standards,and selects the total energy consumption of buildings,UDI_200~2000and The three indicators of population comfort satisfaction percentage are used as optimization goals for later simulation analysis;at the same time,the research status at home and abroad is sorted out,and the commonly used research methods and research contents are summarized.In view of the existing building atriums of colleges and universities in cold regions,through the analysis and characteristics of the atrium types,this thesis finally selects three typical atriums in the teaching building of the School of Architecture of Shandong Jianzhu University,the teaching building of the School of Art of Shandong Jianzhu University and the library of Shandong Jianzhu University As the research object,two typical climatic days in winter and summer are selected for field measurement,and the main problems and solutions in the atrium are analyzed.Through the analysis of common simulation software and optimization plug-ins,the simulation process is determined.Based on the real building scale,the atrium model is established in Rhino,and the performance simulation model is generated through Ladybug and Honeybee.The skylight,side window area ratio,glass type and sunshade The plate rotation angle and interval width are used as optimization variables to simulate and analyze the light-thermal environment and energy consumption level in the atrium.Combined with Octopus,the multi-objective optimization is carried out,and the non-dominated solution set is obtained.Combined with the non-dominated solution set,the correlation between optimization variables and optimization objectives is summarized and analyzed through SPSS,and optimization schemes are proposed according to different optimization directions,which provide strategies for the optimization and reconstruction of existing atrium buildings in universities in cold regions...
