Abstract: Based on the analysis of the characteristics of existing natural ventilation performance optimization methods, the optimization process based on response surface suitable for design stage was proposed. The core steps were: parameter sensitivity analysis, experimental design, response surface model construction, multi-objective optimization, and collaborative optimization platform was established by using ANSYS Workbench. Taking the typical space model of the National Fitness Center as an example, 11 geometric parameters were explored as input variables, and the air age, temperature and wind speed were selected as the optimization targets. By using the parametric modeling technology and CFD numerical simulation technology, 200 sets of data were obtained, and the response surface model was constructed by Kriging algorithm. The genetic algorithm was used to call the response surface model data for fast optimization, and finally the optimization candidates and the optimization interval of each geometric parameter were obtained. -
