基于风环境与遗传算法的建筑体块生成方法--以某综合体设计为例

Building Block Generation Method based on Wind Environment and Genetic Algorithm:Taking a Complex Design as an Example

高速发展的城市化背景下,方案设计阶段由体块设计带来的风环境影响不容忽视。文章基于风环境,开发了一组融合遗传算法的计算流,以期支持建筑体块生成。以某综合体设计为例,在体块生成阶段,使用CFD模拟评估不同参数下建筑体块的风环境,结合遗传算法,利用全年情况下风环境对人体舒适度的影响作为评价标准,寻找了一组能够使室外风环境更优的影响建筑体块形式的参数组合。考虑风环境的建筑设计能够有效提升建筑整体舒适性。该方法作为参数化设计的补充,有望成为建筑师在设计过程中可供选择的新工具。

In the context of high-speed urbanization,the negative impact of wind environment on building block generation design cannot be ignored.This study aims to develop a method that can consider the wind environment in the design of building blocks based on genetic algorithm.Taking a complex design as an example,CFD simulation is used to evaluate the wind environment of building blocks under different parameters,and combined with genetic algorithm,a set of building blocks with better wind environment under variable parameters is calculated and generated.This method is expected to be a new tool for architects in the design process as a complement to parametric design.
