The construction industry is the country's “carbon emitter”. According to the study on carbon emissions from construction and urban infrastructure in china, published jointly by the china association for building and energy conservation and the university of chongqing on 27 december 2023, total carbon emissions from housing construction in china amounted to 4. 07 billion tco2 in 2021, representing 38. 2 per cent of national energy-related carbon emissions. Of this, 2,300 million tco2 were carbon emissions during the construction operation, representing 21. 6 per cent of the country and 56. 6 per cent of total carbon emissions. When considering infrastructure, the share of national energy-related carbon emissions throughout the construction industry was 47. 1 per cent. The construction industry as a whole still has three characteristics: large construction, high consumption and large emissions。
Windows and doors are the weaknesses in the temperature of the surrounding structure and the energy lost through the outside windows of the house is a major factor affecting the building heat environment and causing excessive energy consumption. The data show that construction energy consumption in the country is more than one third of the total energy consumption in society, while construction energy consumption through doors and windows is as high as 50 per cent. In the context of global emission reductions, countries around the world are raising the energy-saving requirements of doors and windows and driving the upgrading of efficient door and window systems and tectonic technologies. At the same time, under the 3060 double carbon policy, energy conservation in construction has become an indissoluble topic in the real estate sector, forcing construction to move towards high-quality development. Faced with this market situation, the royal window, a well-known brand of china's doors and windows, has continued to focus on the development and innovation of external windows for temperature protection systems, making active use of research and development and technological advantages, creating high-quality and energy-efficient system doors and windows, and accelerating the development of products in a green low-carbon direction。
The external window temperature protection system includes parts such as broken aluminium alloy window frames, mid-empty glass, and broken node treatment techniques connected to window holes. The royal gate and window develops innovative energy-saving technologies and products for building systems and windows, while ensuring the sealing of windows through the face-to-face retrofitting of door and window frames, the increase of the insulation cavity, the filling of insulation materials, the introduction of scalable seals, the use of multiple layers of mid-empty glass, and the introduction of five-star installation standards for the royal gate and window at the installation stage, the improvement of the energy efficiency of the doors and windows in all directions, the reduction of heat consumption by air leakage and cold wind penetration, and the effective reduction of household dependence on heat and refrigeration equipment, as well as the reduction of the loss of home-based heat and of building carbon emissions。
Among the main technical indicators for energy-saving doors and windows, the heat transfer factor is the amount of heat that passes through the window or glass curtain wall within a unit time at a temperature difference of 1 k (°c) on both sides. The indicator indicates the ability of doors and windows to prevent the loss of heat, and the lower the value, the better the temperature. In accordance with the certification requirements for the energy efficiency of building doors and windows, the heat transfer factor for normal aluminium alloy energy-saving doors and windows is 2. 5-4. W/m2 k, the heat transfer factor for broken aluminum alloy windows is 2. 0-3. 5w/m2 k, and the window openings for broken window windows and windows of the royally assigned window and window of the wall of the bridge of thermal insulation are reduced to 1. 96 and the “heating insulation” of doors and windows beyond the gb/t8478-2020 standard of the <2. 5” is a new standard for thermal insulation of doors and windows for users。
High performance temperature-preserving system doors and windows, glass performance is critical, and high performance glass products are one to several times more insulated than normal glass. In general, middle glass is separated from two steeled glass, with dry air between them, which is then sealed with sealed materials, thus providing better insulation. At the same time, thermal resistance of mid-empty glass is large, blocking the flow of heat outside the room and maintaining the comfort of indoor temperature. The royal virona windsor series products are marked with two layers of hollow steeled glass, with greater hardness and resistance to shocks than normal glass, greater temperature tolerance and higher safety factors。
The queen's gate and window has been working to reduce carbon in door and window products. Through innovative awareness and technological accumulation, in 2023 the queen's gate and window were awarded a carbon footprint certification for products such as an open window in the queen's house of representatives, a series of products such as an open aluminium alloy window in the queen's house of representatives was successfully certified and approved by the china institute of building sciences, and china's certification certificate for green building materials was awarded “tristar class” certifications, as well as a number of green authority certifications, reflecting the systematic effectiveness of the queen's gate and window in reducing energy consumption of products, providing a healthy quality habitat for the public and contributing positively to global greenhouse gas emission reduction actions。
Processing equipment was particularly important in the area of doors and windows, for which reason royal doors and windows had been introduced into advanced automated production lines abroad and smart manufacturing plants had been built. In smart workshops, which have smart sawning, cnc smart processing, assembly flow water lines, gel intelligence packages, assembly of debugging flow water lines, smart packaging reservoirs, etc., the production process data acquisition analysis system, mes integration, etc. Have been set up to increase efficiency, reduce loss and loss, ensure quality, etc., and promote green manufacturing upgrades with intelligent production。
Through innovative technologies and the introduction of advanced smart equipment, royal doors and windows not only improve the quality of products, but also drive china's door and window markets into a new era of “high standards and high quality”. In the future, the royal doors and windows will continue their corporate mission of “making high-quality doors and windows, making buildings more energy-efficient and contributing to the achievement of double-carbon goals”, working for the development, design and manufacture of energy-efficient doors and windows, expanding the supply of high-quality, low-energy, green window products, meeting the growing needs of users for a better life and contributing to a green, low-carbon transformation of society。
