Johnson (Johnson & Johnson) good energy-saving products for glass doors, windows and curtain walls of glass membrane buildings

the low-carbon development of China's construction industry is mainly reflected in the promotion of building energy conservation and green buildings. The promotion and adoption of building energy-saving products to the maximum extent and the effective implementation of national policies and regulations on energy conservation and emission reduction have become more and more important issues in the practical work of government departments at all levels and relevant construction units. In accordance with the 11th five year plan, the design standard of 50% energy saving will be fully implemented for new buildings, and a national standard system and technical support system of 65% energy saving will be established in four municipalities directly under the central government and the northern region. Protecting the environment and reducing pollution are very important in the energy-saving design of new buildings and the energy-saving renovation of existing buildings in the future

at present, the total amount of new buildings in China is about 2billion square meters every year. There are about 40billion square meters of buildings. There are about 13billion square meters of buildings that need energy-saving transformation. The annual demand for exterior doors, windows and curtain wall glass is about 3. More than 300million square meters

China's building energy consumption accounts for more than 1/3 of the country's total energy consumption. The unit energy consumption of civil and public buildings is four times that of Europe and three times that of the United States. Non energy efficient buildings account for more than 95%. The energy consumption lost through doors and windows accounts for more than 40% of the total building energy consumption. The energy saving problem of exterior window glass has become quite prominent and urgent. The application rate of energy-saving glass in many foreign countries is quite high, such as 92% in Germany, 90% in South Korea, 75% in Poland, and less than 10% in China. It can be seen that there is still a big gap in glass energy saving in China, and the task is very arduous

in 2005, the Ministry of Construction issued the design standard for energy efficiency of public buildings and the notice on strictly implementing the design standard for new residential buildings. Beijing, Tianjin, Shanghai, Shandong and other provinces have also introduced new building energy efficiency design standards. Beijing proposed that the heat transfer coefficient K of doors and windows should be ≤ 2. 8w/㎡。 K

China national building materials and Equipment Co., Ltd. (http://www.johnsonfilms.com) has taken leading the development of the industry as its own responsibility in many years of work practice, and has made scientific and technological innovation in building materials engineering and products; R & D design; The introduction of high-tech products has always been in the leading position in the industry. For many years, under the leadership of Sinoma Group, a large central enterprise directly under the SASAC, we have been unremitting in the field of building materials, persistent in exploration and bold in innovation. Great achievements have been made in large-scale engineering construction at home and abroad, promotion and application of high-tech products, etc

since 1996, the national building materials administration led the introduction of Johnson (Johnson) glass film (http://www.johnsonfilms.com) from the United States and China Building Materials Equipment Co., Ltd. led the industry to promote its use nationwide, Johnson (Johnson) glass film has solved China's architectural glass problems to a certain extent; Safety glass and automobile glass have long-standing problems and troubles in energy conservation, safety and environmental protection. It has created good social and economic benefits. Johnson glass film not only has incomparable advantages over other products in terms of advanced functionality and convenient construction operability, but also highlights its energy conservation in the use of architectural glass, safety glass and automotive glass; Safety; Block 99% ultraviolet light; Anti glare; Beauty, durability and privacy protection. In recent years, we have undertaken a large number of excellent engineering application cases, which have also proved its superior characteristics and irreplaceable role. If; The general office building of the customs, the National Grand Theater, the China Millennium Monument, the office building of the head office of the China Construction Bank, the capital airport, Nanning International Convention and Exhibition Center, the Palace Museum, the State Electricity Corporation, Howard Johnson Suzhou, the Ministry of Railways of Turkmenistan, Shanghai Huanqiu financial center, the office building of the Qingdao municipal government, the Beijing Olympic venues, the National People's Congress conference center, the Shanghai WorldExpo exhibition hall And a large number of new or reconstructed glass renovation projects at home and abroad. With a total area of more than one million square meters, it has won praise from the industry and users for its perfect multi-functional glass solutions

scientific and reasonable selection of window glass and Johnson (Johnson) glass film (http://www.johnsonfilms. Com) with the characteristics of high efficiency and energy saving is one of the effective measures to solve the problem of building energy saving. At present, the more common energy-saving glass includes: heat absorbing glass; Heat reflective glass; Low-E glass; Hollow glass; Vacuum glass; Coated glass

· heat absorbing glass - it can reduce 20%-30% of the solar energy entering the room. It is characterized by low shielding coefficient, low solar energy penetration, low direct sunlight penetration and low direct sunlight reflectivity. Its visible light reflectance, heat transfer coefficient and emissivity are similar to those of ordinary glass

· thermal reflective glass - the reflectivity can reach 20%-40%, or even higher. Its shielding coefficient, total solar penetration, direct solar penetration and visible light penetration are low. Direct reflectance of sunlight, high reflectance of visible light. The heat transfer coefficient and emissivity are similar to those of ordinary glass

· Low-E glass with low emissivity. Its shading coefficient, total solar penetration, direct solar penetration, direct solar reflectance, visible light penetration and visible light reflectance are similar to those of ordinary glass. Its emissivity and heat transfer coefficient are relatively low

· hollow glass - it is characterized by low heat transfer coefficient, about 40% lower than ordinary glass. It is a commonly used insulating glass at present. Combined with different series of Johnson glass functional films, it will produce excellent energy-saving effect in 2014. At the same time, it has the functions of safety, blocking 99% ultraviolet rays, preventing glare, beauty, privacy protection, durability, etc

· vacuum glass - the heat transfer coefficient of vacuum glass of the same material is at least 15% lower than that of hollow glass. However, due to its high production conditions and process requirements, it does not have the conditions for large-scale production and use

· coated glass - the effect of heat absorption, heat reflection or low radiation can be achieved by coating on ordinary glass. With the continuous development and innovation of glass deep processing technology, especially the rapid development of film technology, some new coated glass products are not energy-saving glass with single function, but energy-saving glass with multiple functions. For example, the solar controlled low radiation coated glass combines the characteristics of heat reflection, low radiation and heat absorption

compared with other glasses mentioned above, coated glass has obvious functional advantages in practical use. In terms of thermal insulation, compared with coated glass, coated glass not only has the functions of heat absorption and heat reflection better than coated glass, but also the thermal conductivity of polyester film itself is much lower than that of glass, which makes the thermal conductivity of coated glass lower than that of other glasses under the same conditions. In terms of safety and explosion-proof performance, coated glass has no safety and explosion-proof performance, while coated glass itself is safety glass. Its safety and explosion-proof performance is similar to that of equivalent laminated glass, and is better than laminated glass in terms of splash prevention

compared with LOW-E glass, coated glass is more "broad-spectrum" in use area and climatic conditions. Low-E glass has high far-infrared reflectance, and its barrier to near-infrared is similar to that of ordinary glass. Most of the heat energy of the sun is transmitted in the form of near-infrared ray. Therefore, Low-E glass is more suitable for use in cold areas where indoor heating facilities are required for heating and sunshine is required to supplement heat in winter. In the hot south most of the time, people need to use air-conditioning refrigeration to reduce the indoor high temperature. The "Yang stop power transmission" brand can only bring more heat, which can only make the air-conditioning energy consumption greater and the technical level of complementary exchange greater. In terms of safety performance, Low-E glass also has no safety performance like ordinary glass. It can meet the requirements of safe use only by sticking film. In addition, the coating of Low-E glass is easy to oxidize, and the effect of single piece is not good. Generally, it is made of hollow glass. Its shelf life is about five years. Johnson Johnson films (http://www.johnsonfilms.com) has designed a series of glass functional films with different functions according to different regions and climatic characteristics, which can fully meet the energy-saving and safe design and use needs under various conditions. And the shelf life of the product can reach more than 20 years. American Johnson (Johnson & Johnson) glass membrane with different functions can be used together with insulating glass and Low-E glass to achieve almost perfect application effect

now, more and more designers and construction units have realized the urgency of building energy conservation, but they are not mature in the selection and application of energy-saving products. The above introduction is intended to provide you with a choice in solving the energy-saving and safety problems of window glass and curtain wall glass. Let us join hands to make due contributions to the cause of building energy conservation and emission reduction in China
