摘　　要：大面积玻璃幕墙是建筑能耗的薄弱环节。以北京市某座全幕墙写字楼为工程实例,首先对建筑采暖制冷能耗进行能耗模拟计算,对项目已匹配在用的既有制冷机组进行评估。然后,选取不同热工性能参数的玻璃幕墙进行模拟计算与分析,探索适合当地气候条件的热工性能参数的幕墙玻璃,为建筑师、开发商在设计选择玻璃幕墙材料时提供借鉴与参考。Large area of glass wall is the weak point of energy-efficiency. Taking a full glass wall office building as an example, firstly estimated the building cooling and heating loads by numerical simulation, and then evaluated the existing cooling system. Secondly, numerically simulated and analyzed varied parameter of thermal performance of glass curtain wall, so as to grope for the appropriate glass adapted to the local climate. Finally, architects and developers could take the result as reference when selecting the material of glass curtain wall.
