基于节能模拟的高架车站建筑设计优化策略

Optimization of Elevated Station Design Based on Energy Saving Simulation

通过在节能软件中模拟巴基斯坦拉合尔当地热环境,对高架车站朝向、外窗遮阳形式、公共区舒适性和外窗玻璃构造及面积进行分析,得到以下结论:(1)建筑应选择当地建筑的最佳朝向,南偏西10°;(2)选择围护结构蓄热的被动式降温策略;(3)同一种遮阳构件及间距的条件下,采用垂直遮阳形式效果更好;(4)采用空气空调系统维持高架车站公共区的舒适性环境,为减少冷量损失采用双玻璃的外窗,在满足外窗面积及排烟要求的情况下,外窗与外墙面积比例应尽量小。

Through the simulation of Lahore＇s local thermal environment in the energy -saving software, this paper analyzes the orientation of the elevated station, the form of shade of the outer window, the comfort of the public area and the area of the outer window glass. The conclusions are as follows： （1） The best direction is the south west 10° ;（2） the best passive cooling strategy is structure heat storage; （3） With the same shade components and spacing conditions, the use of vertical shade is better; （4） Adopting air - conditioning system to maintain the comfortable environment in the public area of elevated station. To reduce the cooling loss, double -glass outer windows shall be used to meet the requirements of outer window area and smoke exhaust. The ratio of outer window to outer wall area should be assmallas possible.
