世界建筑科学技术突飞猛进,房屋建筑快速发展,建筑围护结构的保温隔热和气密性能大有提高,采暖、空调和照明的设备与技术日益进步,使人们能够在更为优裕和舒适的室内环境中生活与工作,人类建筑文明取得了前所未有的成就。在此同时,人们也不得不面对着资源枯竭、环境恶化、生态破坏、气候变暖等一系列严峻问题。强调节能、低污染、低耗能的绿色建筑顺应时代的要求而生。虽然玻璃幕墙建筑采用遮阳措施能达到更好的隔热节能作用,但在国内,现阶段各方对此重视不够。一栋设计不良的全为玻璃幕墙建筑的全年空调耗电量,可能是一般混凝土外墙大楼的四倍。而玻璃幕墙的使用寿命达五十年 The world’s building science and technology by leaps and bounds, the rapid development of housing construction, building envelope insulation and air tightness greatly improved performance, heating, air conditioning and lighting equipment and technology advances, enabling people to be more comfortable and comfortable indoor environment In life and work, human civilization has made unprecedented achievements. At the same time, people also have to face a series of serious problems such as resource depletion, environmental deterioration, ecological destruction and climate warming. Emphasize energy-saving, low-pollution, low-energy green buildings conform to the requirements of the times. Although glass curtain wall construction with shade measures can achieve better thermal insulation energy saving effect, but in our country, all parties at this stage pay insufficient attention to this. The year-round air-conditioning power consumption of a poorly designed all-glass curtain wall building may be four times that of a typical concrete facade building. The glass curtain wall life of up to 50 years
