Background

Energy conservation and emission reduction play a significant role in social sustainable development and are also tasks and challenges facing all countries in the world at present. In 2006, the energy consumption of civil buildings (operation) in China accounts for 23.1% of the total energy consumption of the society in the current year, and the total energy consumption amount is continuously increased along with the improvement of urbanization rate, economic development and the continuous improvement of income and living standard of people, so that the reduction of the energy consumption of buildings is one of the most important tasks of energy-saving work. The most direct factor influencing the energy consumption of the building is the heat insulation performance of the building enclosure structure, and the door and the window are the weakest parts of the heat insulation in the enclosure structure and are the most main factors influencing the energy saving of the building. As for the typical building envelope structure in China at present, the energy consumption of the doors and the windows accounts for about 40 to 50 percent of the total energy consumption of the building envelope structure.

The LOW-E glass has single silver, double silver and triple silver, but the glass has undesirable heat insulation effect in summer and obvious heat insulation effect in winter. In order to solve the problem of short plate of LOW-E glass with insufficient heat insulation performance in summer, heat insulation and heat preservation glass is developed, and a 6(LOW-E) +12A +6 (heat insulation) structure is adopted at present, and the heat transfer value is about 1.6-1.8W/(m.K). However, the heat transfer coefficient of the window is still 0.95W/(mK) higher than that of a wall body, which is 0.65W/(mK), so that the heat insulation effect of the window is still not ideal even if the current best technical scheme is adopted.
