自然通风是重要的绿色建筑被动式设计策略，对于节能减排、提高建筑环境舒适度和改善室内空气品质等方面具有至关重要的作用。计算流体动力学(简称 CFD)是近代流体力学、数值数学和计算机科学结合的产物，将其运用在绿色建筑设计领域，能够为更精确地预测设计方案的建筑风环境提供依据，建筑师结合建筑技术科学的相关知识与模拟的结果进行分析，进而多方案比选和优化建筑设计方案。从总体布局、建筑形体、围护界面3个层面通过 CFD 风环境模拟来进行建筑自然通风优化的方法与实例研究，为建筑风环境的优化设计提供思路。

Natural ventilation is an important passive strategy of green building design, It plays a crucial role in conserving energy, reducing emission, enhancing comfort level of built environment, and improving indoor air quality. Computational Fluid Dynamics (CFD for short), as the combination of modern fluid dynamics, numerical mathematics and computer science, could offer the architect an important basis to optimize the architectural design when applied to the green building design. In combination with relevant knowledge in science of building technology and the simulation results, it can analyze the strength and weakness of various design options and optimize them. The paper shows the methodology and case study of optimizing the building’s natural ventilation through CFD wind environment simulation from three aspects, i. e. master layout, building form and envelope interface, thus offer some ideas for optimizing the building’s wind environment.
