Research On Optimal Design Strategy Of Teaching Building Based On The Improvement Of Photothermal Performance

Green,low-carbon and intelligent buildings are important trends in the future development of China’s construction industry.At the same time,it is also the key to implement the "double carbon" goal,meet people’s health and comfort needs and promote the high-quality development of the construction industry.In recent years,with the comprehensive promotion of the strategy of rejuvenating the country through science and education,creating a good educational environment for the healthy growth of teenagers has become the common aspiration and goal of the whole society.At present,the safety quality of the existing primary and secondary school teaching buildings has reached the standard,but the indoor and outdoor physical environment comfort of the teaching buildings is low,and the energy demand and carbon emission generated by the teaching buildings will inevitably increase,which will bring severe challenges to the realization of "carbon peak" and "carbon neutralization" in our country.To solve this problem,it is necessary to conduct in-depth research on the behavior mode and comfort needs of building users,consider the impact of seasonal differences on indoor and outdoor comfort,synchronously optimize the multiple performance of the building in the scheme stage,and find an appropriate integrated design strategy.Therefore,it is of great significance to carry out the research on the optimal design strategy of primary and secondary school teaching buildings with improved photothermal performance.First,through the questionnaire survey,case investigation and field measurement of primary and secondary school teaching buildings,sample statistics and analysis are carried out on the layout form and internal space of primary and secondary school teaching buildings in cold areas,the design methods of primary and secondary school teaching buildings are summarized,the problems existing in the indoor and outdoor physical environment are found,and the corresponding evaluation indicators are put forward,so as to provide a basis for further research on the optimal design strategy of primary and secondary school teaching buildings based on the improvement of photothermal performance.Secondly,the influencing factors of outdoor thermal comfort of primary and secondary schools are analyzed.A parametric simulation analysis platform is built in grasshopper,and the layout analysis model of the teaching building is established.From the four design factors of D / h value,orientation,enclosure mode and shape design of the teaching building,the influence on the outdoor thermal comfort of the teaching building in winter and summer is explored,and the optimization design strategy is put forward.On this basis,using SPSS statistical analysis software,an orthogonal experimental model with four factors is established to explore the optimal strategy under the integrated design factors.Thirdly,the influencing factors of indoor light and heat performance in primary and secondary schools are analyzed.A parametric simulation analysis platform is built in grasshopper,and the internal space analysis model of the teaching building is established.The effects of thermal comfort and daylighting are analyzed from four aspects: plane combination mode,classroom space scale,classroom window opening and sunshade,and the optimization design strategy is put forward.On this basis,combined with the analysis platform,the optimization design platform of photothermal comprehensive objectives is built in grasshopper.The experimental research on photothermal comprehensive objectives is carried out from three aspects: optimization algorithm,optimization process and set quality,so as to explore the optimal strategy solution set under the influence of photothermal comprehensive objectives.Based on the above research,combined with the design practice of a primary school teaching building in Jining,this thesis investigates and analyzes the layout form,classroom space scale,window opening and shading mode of the project,as well as the field measurement of outdoor thermal environment and indoor photothermal environment,and puts forward the optimization design objectives and optimization design scheme suitable for the teaching building of the project.Based on the "Lady Bug tools" and "honeybee" plug-ins in grasshopper,the geothermal comfort of teaching building and the light and heat comfort of ordinary classroom are simulated.The results show that through the design practice of a primary school teaching building in Jining,the teaching building not only meets the basic functional requirements,but also effectively improves the indoor and outdoor light and heat comfort performance.Therefore,the research results can provide reference and reference for promoting the design of teaching buildings in cold areas.
