China's building energy consumption accounts for about 30% of the country's total energy consumption, building energy consumption level is four times that of Europe, the United States three times, not energy-efficient buildings accounted for 95%. Heat transfer through the windows and doors energy consumption accounts for about 28% of building energy consumption, energy consumption of air infiltration through the windows and doors building energy consumption accounts for about 27%. China's future building energy efficiency is the key energy-saving doors and windows. Low-E glass on the short-wave radiation of transparency, so that the basic through the ultraviolet and visible light, while the long-wave infrared radiation is not passed. Namely, to maintain indoor winter heat, making it difficult to misinformation, while the summer outdoor temperature emit thermal radiation to block out a large number, making it difficult to enter the room, so that "Dongnuanxialiang" and thus have excellent energy-saving effect. Governments around the world since the 70's to adopt policies to promote energy-saving building materials, and promoted the use of low-e glass. Of his stay abroad was high. In Germany, low-e glass, the utilization rate reached 92%, South Korea 90%, Poland 75%. At present, China energy-saving glass penetration is only about 10%, low-e glass penetration is only about 2%, a large space. After 2002, China promulgated a lot of building materials energy conservation policy. In 2006 against the glass of the introduction of a "flat glass industry restructuring on the promotion of a number of opinions" encourages the use of low-e glass. Jiu San Society presented two sessions this year, "on promoting the development of China's proposal for low-carbon economy" has been listed as sponsors on the 1st session. Building energy efficiency hiccups have risen again. Low-e glass, mainly: (1) off-line Low-e glass can not be single use or storage, may be required to complete the color of a product, mainly used in commercial buildings, such as high-end architecture; (2) Online Low-e glass, can be single use, long-term storage, non-perishable, color, gray-blue and the net only two kinds of color, variety simple, mainly used in civil construction. Currently only about two-line Low-e glass production lines, most of the other for off-line Low-e glass production line production line. To leading the company CSG, for example, 80% of the market as the public and installed off-line market. In 2009 China's building carboxylic area calculation, if only 40% of hollow glass or thermal emission energy-saving glass coated replaced LOWE change is 40 million square meters. Low-e glass CSG project 2009 annual capacity of approximately 13.5 million square meters, high-end construction market share of 50% of the glass is definitely the industry leader (brand is an important competitive advantage). The present planning under construction in 11.4 million square meters, 2012 Low-e glass project to almost double capacity, of which nine million square meters large panel coated glass primarily for the civilian market.
