Window Design Of Office Buildings In Cold Climate Area Based On Multi-objective Optimization Algorithm

With the development of speed up,people gradually realize the urgency and importance of energy conservation.With the rapid development of sustainable architectural design,various countries have introduced a suitable assessment system for their national conditions.And the most common point of these evaluation systems is to use specific figures to measure the performance of buildings.Therefore,it is very important to simulate the performance of the building in the architectural design stage.On the other hand,the evaluation system is a comprehensive evaluation of the conflicting,nonlinear multi-performance.Accordingly,it is of great significance to study the multi-objective optimization of building performance.Taking into account the above issues,based on the basic theory of multi-objective evolutionary algorithm,this paper proposes a multi-objective performance optimization platform of the architectural design stage based on Grasshopper software.The aim is to provide a quick and effective method for the optimum design of sustainable architecture.It is worth noting that the workflow for the optimization of objects and objectives are not restricted,can be based on specific circumstances.In order to verify the application of the working platform,and to make the research result more extensive,the standard model of the space form construction of the corridor in the office buildings in the cold area was extracted.The standard model is extracted as the final research object.Based on the establishment of a integrate simulation and optimization platform,the annual total energy consumption is smaller,the greater the daylight uniformity,the smaller the daylight glare probability as the optimization targets,the optimization design of building window parameters is carried out.At the same time,the convergence,distribution degree and comprehensive evaluation index of the simulation results are analyzed.The parameter system of the quantity influence of the window parameters is established for the annual total energy consumption,daylight uniformity and daylight glare probability.And a series of parametric design models,based on the integrated optimal solution of the building energy consumption and lighting quality,are obtained.The paper has three innovations: First,the standard model of gallery plate office building in cold area was extracted.Provide the theoretical basis for the standard model extraction of other building types,and make the research results more universal.Second,a integrate simulation and optimization platform and workflow based on the window of office building is put forward.Improve the efficiency of sustainable building design.Third,a series of parametric design models,based on the integrated optimal solution of the building energy consumption and lighting quality,are obtained.It can provide parameters support and reference model for the window design of the interior gallery type office building.
