Description

Technical Field

[0001] The present application relates to the technical field of building curtain walls, and in particular to a green and energy-saving building glass curtain wall. Background Art

[0002] Glass curtain wall is a building facade system, mainly composed of glass and metal frame, usually used for the exterior decoration of modern large and high-rise buildings. Glass curtain wall can provide a transparent appearance, and large areas of glass can bring in natural light and reduce dependence on artificial lighting. Compared with traditional wall materials, glass curtain wall is usually lighter and can reduce the overall load of the building.

[0003] Green and energy-saving architectural glass curtain walls refer to curtain wall systems that can effectively reduce energy consumption, reduce environmental pollution, and improve the sustainability of buildings. For example, glass materials with good thermal insulation properties are selected to reduce indoor and outdoor heat exchange and reduce air conditioning energy consumption. These glass materials can effectively reflect infrared thermal radiation and reduce radiation heat transfer, thereby improving the energy-saving performance of the curtain wall. Green and energy-saving architectural glass curtain walls also need to consider ventilation when designing. Usually, an openable and closable design is adopted. When ventilation is needed, the glass windows can be opened outward to let in outside air, ensuring the quality of indoor air circulation and reducing the energy consumption required for the operation of the indoor ventilation system, thereby achieving a certain energy-saving effect.

[0004] However, there are certain safety hazards in the openable and closeable glass curtain wall. The glass windows that open outwards will be subject to greater wind pressure.
