【摘要】 根据所处地区气候环境,研究城市内部空间通风环境优化,作为城市建筑空间形态控制指引要素,有利于提高建筑形态决策的科学性。结合标准化风温指数、地表通风潜力和夏季热岛强度,对北京中心城区建筑空间形态设计进行了气候分区。通过气象数值模拟,得到不同气候分区中典型城市单元的近地面风速和气温,构建出城市单元风温数据样本,经回归分析确定了单元建筑高度、密度和容积率与标准化气候指数之间的关系。以单元建设后的标准化气候指数更优化为原则,计算给出不同气候分区内的建筑空间形态控制指引。更多还原

【Abstract】 According to the local climate environment,this paper studies the optimization of ventilation environment in urban space,and takes it as one of the control elements of urban building space form,can improve the scientificity of building form decision-making.The climate zoning of building space form design in central urban area of Beijing is carried out by using the standardized wind-temperature index,surface ventilation potential and summer heat island intensity.Then the near surface wind speed and air temperature of 36 typical urban units in different climate zones are numerically simulated by using the city sub-domain scale model,which are used to construct the wind and temperature data samples for regression analyzing the correlation between building control index(height,density,plot ratio) and standardized wind-temperature index.At last,based on the principle of more optimization of standardized wind-temperature index after unit construction,the control guideline s of building space form in different climate zones are given.更多还原
