某办公楼冬季室外风环境模拟分析及评价研究

Simulation analysis and Evaluation of Outdoor Wind Environment in an Office Building in Winter

近地风的状况与建筑物的外形、尺寸、建筑物之间的相对位置以及周围地形地貌有着很复杂的关系。在有较强来流时,建筑物周围某些地区会出现强风;如果这些强风区出现在建筑物入口、通道、露台等行人频繁活动的区域,则可能使行人感到不舒适、甚至带来伤害,形成恶劣的风环境问题。为了更好的设计、评价绿色建筑,达到国家《绿色建筑评价标准》GB/T 50378-2014关于室外风环境的要求,现对某办公楼冬季室外风环境进行模拟分析。

There is a complex relationship between the condition of the near-earth wind and the shape,size,relative position of the buildings and the surrounding topography.Strong winds occur in certain areas around buildings when there is a strong flow.If the wind zone is located at the buildings'entrance,channel,terrace or the pedestrian area with high people volume,the pedestrian may feel uncomfortable and even get hurt,which constitutes a bad effect of the wind environment. For a better evaluation and design of green building,and to meet the national "green building evaluation standard" GB/T50378-2014requirement,a simulation analysis about the outdoor wind environment within an office building in cold areas during winter season has been established here.
