确定了天津市第四阶段建筑节能耗热量指标,通过对外墙保温厚度的经济性分析,给出了寿命周期内推荐的外墙传热系数.指出建筑外窗传热系数应按照各朝向面积加权平均方法选择.通过对南向外窗的耗热量计算分析,认为天津地区建筑南向窗墙面积比可适当放大.探讨了建筑体形系数的控制方法.
確定瞭天津市第四階段建築節能耗熱量指標,通過對外牆保溫厚度的經濟性分析,給齣瞭壽命週期內推薦的外牆傳熱繫數.指齣建築外窗傳熱繫數應按照各朝嚮麵積加權平均方法選擇.通過對南嚮外窗的耗熱量計算分析,認為天津地區建築南嚮窗牆麵積比可適噹放大.探討瞭建築體形繫數的控製方法.

The fourth stage heat consumption index of residential buildings in Tianjin was decided. Optimum heat transfer coefficient of exterior wall was deprived from the life cycle economic analysis. The heat transfer coefficient of exterior windows should be in accordance with the average value using the different orientation area-weighted method. From the heat loss calculation of south window, it is concluded that the south window ratio can be increased in Tianjin. The regulatory method of the building shape coefficient was also discussed.
