《上海市建筑玻璃幕墙管理办法》的正式实施,使玻璃幕墙的安全性、环保性进一步得到重视。以上海政华大厦旧楼改造工程为例,把玻璃幕墙的原单层玻璃改换为LOW-E中空钢化玻璃,并通过对两种玻璃传热系数的计算,证明中空玻璃传热系数远小于单层玻璃,节能率为61.1%,达到了节能、环保、安全的要求。建议玻璃幕墙选用LOW-E中空钢化玻璃。 The “Shanghai Building Glass Curtain Wall Management Measures,” the official implementation of the glass curtain wall safety, environmental protection has been further attention. Take the old building renovation project of Shanghai Zhenghua Building as an example, the original single-layer glass of the glass curtain wall was changed to LOW-E hollow tempered glass, and the heat transfer coefficient of the two kinds of glass was calculated to prove that the heat transfer coefficient of the insulating glass is much smaller than that of the single layer Glass, energy-saving rate of 61.1%, reached the energy-saving, environmental protection, safety requirements. Recommended glass curtain wall selection LOW-E hollow glass.
