Tessellation-based Designs For Facades To Optimize Daylight And Thermal Performance

As the interactive interface between the building interior and the natural environment,the building skin not only bears the role of shaping the facade,but its optical and thermal properties also have an important impact on the light and thermal comfort environment and energy consumption level in the building interior.The optimization of epidermal light and heat performance is a process of multi-objective coupling analysis of epidermal prototype and quantitative optimization of epidermal morphological variables to improve indoor light and heat comfort.The existing optimization design of skin thermal and thermal performance is difficult in the generation and modeling of skin prototype,but it is inadequate in optimization methods and optimization decisions.The study takes the building skin as an object,and aims to explore the strategy of generating high-performance skin prototypes,construct the skin thermal and thermal performance analysis and shape optimization process,and improve the design decision-making method.Provide new ideas for high-performance and beautiful architectural skin design.Through combing through a large number of cases,the study conducted a type study on the application of mosaic geometry in the design of building skins,and summarized the skin generation strategy of "mosaics as graphics,units respond to light and heat";using the computability of mosaic geometry,based on parameters The modeling thinking constructs the mosaic geometry parametric modeling logic,and mosaic unit change logic;through the summary of the optimization logic and methods of the existing performance optimization theory and the study of key technical characteristics,the use of data sampling technology,performance simulation simulation Technology,data mapping technology and multi-dimensional data analysis technology build a software platform.Constructed a three-layer progressive building skin performance optimization design process of sampling and simulation,light and thermal performance analysis,and multi-objective optimization and decision-making;based on the performance optimization design process,a light and heat performance optimization experiment was carried out on the skin prototype generated by mosaic geometry.The objects were analyzed for photothermal performance potential and sensitivity analysis,and the analysis results were obtained;combined with the multi-dimensional data analysis and visualization method,the optimization decision of the mosaic geometric skin prototype was given,and the optimization recommendation value was given;and the experimental results were experimentally verified,Ensure the accuracy of the experiment.The research validates the scientific and adaptability of building skins based on mosaic geometry,and proves that the design strategy of "mosaic geometry as graphics,mosaic units respond to light and heat" can generate high-performance building skins;The performance optimization process of the analysis realizes the targeted analysis of the high-performance skin design and provides guiding suggestions;it innovatively proposes the potential analysis of the skin thermal and thermal performance targets and the sensitivity analysis of the skin variables to assist the architect to carry out Optimize the decision;expand the performance optimization method to assist the architect to optimize the performance in the plan design stage and create a high-performance skin.
