| In recent years,the development of green building performance simulation technology and parametric design methods and tools are becoming more and more widely.With the rapid development of the economy and the rapid development of the city,the construction of office buildings continues to grow,and the research on energy conservation can not be ignored.Based on daylight performance,the paper carries out themulti-objective optimization experiment of multilayer office building space in cold region,in order to realize the organic combination of architecture generation,performance simulation and optimization,as well as to enhance the efficiency of building design optimization.The paper elaborates the theoretical basis of multi-objective optimization of multilayer office building space in cold region based on daylight performance,including the concept of daylight analysis in multilayer office building space and three daylight performance optimization objectives.It also introduces the technology platform of daylight performance simulation and a variety of optimization algorithm theory.Then process framework of multi-objective optimization of parametric architectural space influenced by performance has been constructed.The process framework is divided into three parts: the building information network construction and the space generation,the building performance index simulation and the multi-objective building space optimization.Firstly,the paper elaborates the construction process of the construction information parameter network and completes the flow of the building performance index simulation,as well as explains the steps of multi-objective building space optimization.And indoor illuminance of the certain conference room research is measured and simulated to verify the simulation accuracy of the technology platform of daylight performance simulation.And based on daylight performance,the process framework is applied to carry out experiment of multi-objective optimization of multilayeroffice building space in cold region.Based on Grasshopper platform,combined with Ladybug and Honeybee daylight simulation technology and Octopus multi-objective genetic algorithm optimization technology,the paper studies the design parameters to determine the optimization objectives,and to ensure the effective use of daylight indoor while reducing the probability of glare phenomenon.The optimization results of the experiment are compared with each otherand analyzed by visualization.Accordingly,the design strategy of multilayer office building space in cold region based on daylight performance is summarized,which makes up the shortcomings of data transmission between performance simulation and optimization in the architecture design,so as to provide a reference for the research on performance simulation and optimization of building design in cold region. |
