After the energy crisis from the 1970s, different systems were developed to boost the thermal performance connected with glass curtain walls. The glass curtain wall will be leading structure of people building's outer protective system. It is the the majority of active and sensitive section of the building's heat alternate and heat transfer. It is 5-6 times of losing the traditional wall, and its energy consumption is the reason the entire building energy consumption. About 40%, therefore , the energy saving of this glass curtain wall has a remarkably important position. colored Laminated glass
In China, with the development from the market economy, building energy conservation is an urgent need for that sustainable development of China's financial system and society. The awareness of energy conservation and environmental protection of construction models and design units is consistently improving, and the electrical power conservation requirements for glass curtain walls are constantly improving. Although the glass drape wall building adopts the shading measures to achieve the desired heat padding and energy saving influence, at present, the parties at this stage don't pay enough attention to the current. A poorly designed building that has a glass curtain wall can consume four times more electricity per year than a typical real façade building. The glass curtain wall is known for a service life of 55 years, and its energy-saving effect is needless to say far superior to short-life atmosphere conditioners, refrigerators, and boilers. For that reason, the energy saving of glass curtain wall homes is more important approach energy conservation of alternative building products. The development of photovoltaic curtain wall shading technology can be the most potential device for building energy conservation.
