摘要:本研究聚焦于建筑设计中的关键组成部分——立面设计，研究总结了两种创新的立面生成算法。首先，基于专家系统的参数化方法，特别适用于方案设计的初期阶段；其次，采用AIGC语义分割平面图，根据该图信息将建筑部品放置在相应位置，这两种方法均支持3D模型导出，提供了丰富的数据信息，包括立面材料用量、造价以及窗地比等，同时借助AIGC技术中的扩散算法，成功润色立面模型的截图，使其呈现出更为逼真的带有周围环境的效果图；最后，通过IFC数据传输格式，实现了模型向Revit的同步，为多专业协同与深度后期设计提供了便捷的解决方案。本研究在提高立面设计效率和质量的同时，为建筑设计领域引入了新的方法和技术。

Abstract: This article focuses on facade design, a key component of architectural design, and summarizes two innovative facade generation algorithms. First of all, the parametric method based on the expert system is particularly suitable for the initial stage of project design. Secondly, the AIGC semantic segmentation plan is used, and the building parts are placed in the corresponding positions according to the map information. Both methods support the export of 3D models, providing a wealth of data information, including the amount of facade materials, the cost of the facade, and the window-to-floor ratio. At the same time, with the help of the diffusion algorithm in AIGC technology, the screenshot of the facade model is successfully polished, so that it present a more realistic rendering with the surrounding environment. Finally, through the IFC (Industry Foundation Classes) data transmission format, the synchronization of the model to Revit is realized, which provides a convenient solution for multi-discipline collaboration and in-depth post-design. This research not only improves the efficiency and quality of facade design, but also introduces new methods and techniques to the field of architectural design.
