Building energy saving doors and windows to develop hardware accessories

Recently, according to the Department of housing and urban rural development of Guangdong Province, with the development of China's economy, the total energy consumption of energy conservation has increased year by year. The proportion of total energy consumption has increased from 10% in the late 1970s to 30% now. With the acceleration of urbanization and the improvement of people's life quality, the proportion of building energy consumption in China may rise to about 35%. According to relevant reports, the energy loss of doors and windows accounts for 40% of the building energy consumption, so the energy-saving development of doors and windows industry is imminent.

Building energy saving and green building is a systematic project. The material selection and construction technology of energy saving and environmental protection also play an important role in the promotion of building energy saving and green building. Wang Hongtao, director of the Research Center for curtain wall doors and windows of China Academy of Building Sciences, thinks that the performance evaluation of building doors and windows can be divided into four categories: safety, energy conservation, applicability and durability. What are the performance indicators related to applicability? Water tightness, lighting performance, opening and closing force, etc., and of course, acoustic and sound insulation performance of air. After 50 years of industrialization, the applicability of doors and windows has not been considered as a key point. With the promotion of prefabricated and passive buildings, high-performance acoustic doors and windows will be widely used.

The walls of prefabricated buildings have interlayer, and the interior contains energy-saving and environmental protection materials. Experts believe that doors and windows, as the carrier of contact with the outside world, should also be improved in terms of energy conservation and quality. Modern people are not satisfied with their own houses, but more to improve their living environment, and aluminum alloy doors and windows are an important link that people must consider.

Sun Lijun, chief engineer of Guangdong Architectural Design and Research Institute, also said in an interview with the media that building energy conservation is a challenge to architects and building materials. In terms of architects, they should be innovative and dare to take risks in material construction and building construction; in terms of building materials, the market for building materials is mixed, and the green standard still needs to be strengthened.

The function and position of the door and window system in the whole building has been significantly improved, but many important functions of the door and window system are realized through hardware accessories. In the field of door and window accessories, the upper and lower hinge parts of the traditional aluminum alloy window are exposed, and the sealant strip needs to be cut during installation, and the overall appearance will be affected after the window is closed, which can not meet the needs of modern energy saving, environmental protection and low-carbon life.

Therefore, as a door and window curtain wall industry closely related to architecture, it is a key link to meet today's user's refined demand and form an interactive system with prefabricated buildings. The door and window system, which accounts for 40% of the building energy consumption, not only needs high-quality energy-saving and environmental protection door and window products, but also needs high-quality hardware accessories and hardware system to realize the major mission of the green development of the door and window industry.
