Background

At present, the building energy consumption of China accounts for about 30% of the total social energy consumption. The outer window is a door for ventilation and lighting of the building, and is also a bridge and a channel for communication and contact between people in the house and the outside. Especially for residential buildings, the arrangement of the exterior window is related to the quality of life, and even the health condition, of the occupants of the house. The outer window is used as a part of a building surface enclosure structure, the energy-saving effect of the building is directly influenced, and according to statistics, the energy consumption of the whole building mainly comprises the following parts, namely 47% of the outer window, 25% of the outer wall, 11% of a stair partition wall, 9% of a roof, 3% of a balcony door, 3% of a door and 2% of the ground. It can be seen that the proportion of energy consumption of the outer window is the largest. Therefore, the improvement of the heat preservation and insulation performance of the external window is one of the important ways for reducing the long-term energy consumption of the building.
