The hottest new regulations for the use of buildin

Xiamen, Fujian delimits new regulations on the use of building energy-saving glass

energy conservation of doors and windows is one of the hubs of building energy conservation in China. The research, development and promotion of new energy-saving, thermal insulation doors and windows and glass are the inevitable trend of building energy conservation

energy conservation of doors and windows is one of the hubs of building energy conservation in China. The research, development and promotion of new energy-saving, thermal insulation doors and windows and glass are the inevitable trend of building energy conservation. The relevant parts of Xiamen will be designated from January 1 next year. Insulating glass must be installed and used in buildings on both sides of the street

traditional glass has defects

according to the introduction, at present, the widely used architectural glass in China includes ordinary white glass, colored glass, coated glass, etc. In terms of function, ordinary white glass has good daylighting, but poor heat insulation and radiation protection functions, which cannot meet the needs of building energy conservation; Colored glass has a certain heat insulation function, but the effect is not significant, the light transmission is poor, the interior is gray and the visual effect is poor, so it cannot meet the needs of high-quality life; Coated glass has certain heat insulation function. However, it reflects a large amount of visible light, which not only causes darkness in the room, but also causes "light pollution" and certain potential safety hazards

insulating glass not only concentrates the advantages of traditional glass, but also overcomes the defects of traditional glass. Keep the hot air out in summer and prevent the loss of heat in the house in winter, so as to reduce the use of energy such as air conditioning and heating, and realize that all additives cannot add too much building energy conservation. Low-E glass is a kind of safety insulating glass, which has been forcibly used in new buildings in Europe, North America and other regions

low-e glass is energy-saving and safe

low-e glass, also known as low radiation glass, uses vacuum deposition technology to form a low radiation coating on the surface of the glass. Low-E glass is the deep processing of ordinary glass, and then the two pieces of glass are "put together", leaving a vacuum space in the middle

Zhang Jianquan, director of the building materials and equipment department of Xiamen Construction and Management Bureau and director of the Municipal Office of wall material innovation and building energy conservation, said that Low-E glass has the characteristics of energy conservation, tranquility and safety, which can block the transmission of heat through the glass, block the hot air out in summer and prevent the loss of heat in the house in winter, so as to reduce the use of energy such as air conditioning and heating and realize building energy conservation

low-e glass is still a kind of magic glass. Its surface is coated with a layer of film. It is visually transparent from indoors to outdoors, but indoors from outdoors. But it has a certain degree of shielding. It is precisely this film that blocks the invasion of ultraviolet rays, prevents indoor objects from fading and aging, and allows a large amount of visible light to enter the room directly, so as to obtain a good lighting effect

at the same time, Low-E glass can be processed into laminated Low-E glass, tempered l0w-e glass and other forms, which has good safety function. Once the glass is accidentally broken, it will crack into small pieces, and will not fall off a whole piece. It can reduce the risk. It is also because of this that Xiamen requires the buildings on both sides of the street to enforce the implementation of safety insulating glass

it is twice as expensive as ordinary glass

since 2005, Xiamen has required that energy-saving glass be used for the external doors and windows of civil and public buildings. At present, the local enterprises producing Low-E glass in Xiamen mainly continue to expand the utilization of domestic high-strength, high toughness - low quenching sensitivity aluminum alloy materials in new aircraft and aerospace vehicles. Renewable plastic granulator equipment manufacturers encounter huge business opportunities. At present, the recycling rate of waste plastics in China is not high, and the sales of glass are good. More and more people begin to recognize and use this energy-saving and safe glass. At present, the price of Low-E glass in the market is 200 yuan per square meter, which is about twice as expensive as ordinary glass, but its energy-saving effect is remarkable, and the energy savings are also considerable. Experts calculated an account on the spot. If a house of about 100 square meters uses Low-E glass, its cost is only more than 2000 yuan higher than that of ordinary glass, but the energy-saving effect is significant and the residence is very quiet
