基于风环境模拟对高层住区布局的优化

居住区风环境是衡量居住环境的重要要素。以合肥市某居住区规划设计方案为样本,选取规划设计阶段的两套方案,运用Airpak软件进行数值模拟,分析两套方案在夏季和冬季不同风场条件下的风环境。依据国家现行标准对1. 5 m人行高度处风速、风压等评价指标进行优劣评价,归纳建筑布局对风环境的作用和效应,得出构建开敞的通风廊道能够充分改善夏季住区内部的通风效果。旨在优化高层住区的风环境,为构建舒适健康的居住区规划设计提供理论指导。

Optimization of High-rise Residential Layout Based on Numerial Simulation of Wind Environment

The wind environment of the residential district is an important factor to measure the living space. Taking the planning and design scheme of a residential area in Hefei as a sample, two schemes in the planning and design stage were selected, and the Airpak software was used for numerical simulation to analyze the wind environment of the two schemes under different wind field conditions in summer and winter. According to the current national standards, the evaluation indexes of wind speed and wind pressure at the pedestrian height of 1.5 m were evaluated, and the effect of building layout on the wind environment was summarized. It is concluded that building an open ventilation corridor can fully improve the ventilation effect of the residential area in summer. This paper aims to optimize the wind environment in High-rise residential areas, and create the theoretical guidance for building a healthy and comfortable residential district environment.
