Abstract: In the view of difficulties and problems in the current villages' planning, which is far from the natural ecology and the spatial form is dull. This article takes villages in Guanzhong, Shaanxi Province as the research objects, uses microclimate and performative research methods, and builds steps of parameter modeling, performance simulation, automatic generation and genetic optimization through the parameterized platform (Rhinoceros & Grasshopper), in order to improve the environmental benefits of the village space from the early design stage, and explore the method and digital design process of village spatial form simulation optimization. Using quantitative simulation, generation, optimization and other series of calculations, taking shape parameters as independent variables, UTCI is selected as the microclimate comfort evaluation index. Taking winter comfort, winter sunshine hours, and summer thermal discomfort percentage as optimization goals, it explores the coupling relationship between buildings and climate environment, and carries out multi-objective genetic optimization optimizes the spatial form design method of the village and provides a reference for the green village planning and design practice.
