Under the background of energy saving and environmental protection, how to choose glass curtain wall reasonably

Under the background of energy saving and environmental protection, how to choose glass curtain wall reasonably

① Material selection is aimed at reducing glare

The glass used for glass curtain walls generally includes clear glass, ultra clear glass, tinted glass, coated glass, low e glass, laminated glass and insulated glass. Glass with glare reduction performance should be selected, and special glass should be used to reduce reflectivity.

② Material selection is based on thermal insulation performance.

The thermal insulation and energy-saving effect of building glass curtain walls are inferior to that of traditional enclosure structures. To achieve the purpose of thermal insulation and energy saving, it is necessary to reduce the overall heat transfer coefficient of the curtain wall. In the structural design, the main consideration is to use thermal insulation profiles and double-layer, triple-layer insulated LOW- E glass.

Double-layer and triple-layer LOW-E insulating glass have different functions in different seasons. Remove most of the radiant heat in summer. Winter can play the role of heat preservation, and prevent indoor heat loss, the disadvantage of this is the investment cost is larger.

③ Material selection is based on sound insulation performance.

If you want to improve the sound insulation performance of insulating glass, choose a high-quality insulating glass structure, such as using laminated glass to synthesize an insulating glass structure, which will have a greater effect of increasing glass damping. PVB film has a certain hindering effect on sound waves, thus effectively blocking the transmission of sound.

 

④ Material selection is aimed at the overall appearance effect.

The glass curtain wall is the outer protective structure of the building and also the coat of the building. The architect uses its rich colors and artistic shapes to express the design concept and create colorful artistic effects.

How to design the glass curtain wall reasonably?

1. Pay attention to the angle of glass curtain wall installation, try not to use glass curtain walls in concave, sloping buildings;

 

2. Glass curtain wall includes exposed frame glass curtain wall, hidden frame glass curtain wall, semi-hidden frame glass curtain wall, point type glass curtain wall, full glass curtain wall, etc.

 

Therefore, the glass curtain wall with an exposed frame or semi-hidden frame should be used as much as possible in the design, because even if the structural adhesive fails, the chance of glass falling will be greatly reduced due to the support and constraints of the frame.

3. Install double-glazing glass in the glass curtain wall, and paste black light-absorbing material on the inner glass, so as to absorb a large amount of light, avoid reflected light from affecting the public, and use our accumulated experience to reduce light pollution as much as possible.

 

4. The glass curtain wall can be used in combination with other materials to avoid light pollution as much as possible.

 

The combination of glass curtain wall and metal thermal insulation and decorative integrated board building materials can effectively reduce the building form factor (the ratio of the external area of the building in contact with the outdoor atmosphere to the volume surrounded by it, the smaller the better for energy saving), and reduce the housing itself. It is conducive to the ecological energy saving of residential buildings, and then achieves the purpose of energy saving, which is very suitable for the current green building construction and the national "double carbon strategy" requirements.

Research and development of new types of glass curtain walls, so as to change the current status quo of glass curtain walls, and reduce all the shortcomings brought about by glass curtain walls is imminent, and hopefully, in the near future, the beautiful appearance of glass curtain wall building is no longer a double-edged sword.
