The data show that the total amount of China is rising year by year, and the energy consumption of the buildings in China currently accounts for 40% of the total energy consumption, wherein the energy lost through doors and windows is 46%, namely about 2.25 hundred million tons of standard coal lost through glass windows every year, which is equivalent to the annual energy generation of 21 three gorges power stations, so the energy conservation of the buildings needs to be grabbed from the doors and windows firstly. The high-performance selective shielding material can enable the glass to have a selective transmission function on a spectrum, and can block infrared light, far infrared light and ultraviolet light and block heat radiation on the premise of transmitting most visible light without influencing lighting, so that the energy consumption of an air conditioner or a heating device is reduced, and the purpose of energy conservation is achieved.
