Research On Multi-objective Optimization Design Of Exterior Windows Of Rural Houses In The Cold Zone A

At present,urban and rural residents in China need to further improve the building environment.The consciousness of energy conservation and emission reduction has been further deepened in architectural design.A series of architectural performance design methods and techniques related to the physical environment of buildings have been further developed.Based on the further application of information technology and optimization algorithm in the field of architectural design,this paper takes the outer windows of agricultural buildings in cold zone A of China as the research object for the corresponding experimental research.Through investigation and comparison,the study first identified the ecological settlement village of hongsipu district,wuzhong city,ningxia hui autonomous region as a typical case.By comparing the latest standards of energy saving and lighting design,the typical problem of multi-objective tradeoff of building performance is identified through the project acceptance data and simulation analysis.Under the support of parametric modeling,joint simulation of building performance,multi-objective optimization algorithm and other technologies and theories,the multi-objective optimization experiment?standard house model experiment,house attached sunshine room model experiment?was designed.Through comparison,three evaluation indexes of Total Building Energy Consumption,UDI_100-200000-2000 and sDA were selected as the optimization objectives of the experiment,and the exterior window types with different performance parameters and the window-wall ratio in different directions were determined as the exterior window performance and scale design variables.With Grasshopper as the experimental programming and operation environment,Ladybug and Honeybee performance simulation plug-in,Octopus multi-objective optimization plug-in were used to generate the building model and set up an experimental platform capable of realizing performance joint simulation and optimization.The multi-objective optimization experiment was carried out after the platform test run and the inspection work was completed.After judging the convergence of the experimental results,a conclusion is drawn by 3d visualization analysis:there is a mutual constraint relationship among the three optimization objectives of Total Building Energy Consumption,UDI_100-200000-2000 and sDA.Through the selection of Pareto optimization solution set in different ways,the optimal design scheme of exterior windows suitable for different household types was obtained.Based on the data collation and analysis,the design strategy of outer Windows of farm houses in cold area A was put forward.The research method of this paper provides a new perspective for the research design of agricultural housing in China,makes up for the shortcomings of multi-objective driven design and parametric design in the field of agricultural housing construction,and provides a reference for the design of agricultural housing exterior windows in cold zone A.
