The shading design of glass curtain wall has a great influence on the users of buildings, on the one hand, it is also the requirement of energy saving. This is the energy saving design of the building's outer structure, which is linked by factors such as windowing, shading and insulation materials. The main factors are:
1. Window and wall opening rate is one of the most important factors affecting external wall energy saving. Reducing window area rate is also one of the important means to reduce energy. However, the pursuit of transparent effect of glass curtain wall can meet the energy demand by reducing window area or improving shading.
2. External shading and glass shading are the second important factors affecting the energy saving of external walls. Glass materials and external shading effect may be affected by the size of shielding rate, but the effect is more obvious after the installation of sunshades. Glass materials can choose reflective glass, high reflectivity glass.
3. Curtain wall building orientation is the third factor affecting exterior wall energy saving design (12% overall). The building should be configured in a north-south direction. Building exterior shading refers to the installation of corresponding shading facilities on the outdoor side of the glass curtain wall. Building exterior shading can block direct sunlight, play a very good shading and heat insulation effect, can effectively reduce the energy consumption of air conditioning, save energy consumption.
The outer side of glass curtain wall sunshade usually has fixed baffle sunshade, movable louver sunshade, etc. Among them, the movable louver shading can adjust the rotation Angle of the louver, control the amount of sunlight radiation into the room, achieve relatively fine dimming, but also control ventilation, has become the mainstream form of shading outside the curtain glass window. Indoor shading refers to the installation of shading facilities on the interior side of the glass curtain wall to shade the sun, adjust the light, protect privacy, decorate the interior and other effects. The effect of indoor sun shading and heat insulation is not as good as that of building exterior sun shading, which has limited building energy saving effect, but it is more flexible to adjust the light and more convenient to clean and care.
The inner side of the modern curtain wall is generally covered with electric opening and closing curtains, rolling curtains, indoor blinds and so on. All kinds of shading methods can also be divided into different types according to the product material and style.
