Shading has been an important part of buildings from ancient times to the present. Traditional building shading structures are generally installed on side windows, roof skylights, and atrium glass tops. The types include Portable Folding Gazebo, curtains, grilles, green vegetation, etc. With the development of buildings and the upgrading of curtain wall products, the external shading system is also constantly innovating in function and appearance. From the form, it is divided into four categories: horizontal shading, vertical shading, integrated shading and baffle shading.
1. Horizontal shading
In front of the glass, a sunshade in the form of an extended and overlapping flat plate can effectively block the sunlight projected from above the glass curtain wall with a large sun height angle. Under different solar azimuth and altitude conditions, the shadow area produced by the shading component also changes. Therefore, it is necessary to carefully consider the shade changes in different seasons and different times when horizontal shading. In low-latitude areas or in summer, because the sun's altitude angle is large, the shadow of the building is very short, and horizontal shading is sufficient to achieve good shading effect. The easiest and most effective way is to use the difference between winter and summer sun height angles to determine the appropriate eaves distance, so that the eaves can block the hot summer sun without blocking the warm winter sun. Horizontal shading is the most widely used. .
2. Vertical shading
The vertical sunshade with the protruding plate arranged in front of the glass can effectively shield the sunlight from the side of the glass window obliquely from the side of the glass window with a small angle. But for large angles, the sunlight falling from the glass window, or the sunlight that is close to the sunrise or at the time of the day, it does not have the effect of blocking. The factor that determines the vertical shading effect is the azimuth angle of the sun. Because it can effectively block the oblique light with a very low height angle, it is suitable for the four oblique directions of the south, east, north, and west.
3. Comprehensive sunshade
The integrated sunshade can effectively block the high-angle and medium-sized sunlight from the front of the glass window. The shading effect is relatively uniform, so it has a wide range of applicability in glass curtain wall construction. The integrated sunshade has the advantages of horizontal sunshade and vertical sunshade, and is more effective for sunlight of various orientations and height angles. Nowadays, many people use concrete to design modernist works with sunshade grille as the main architectural vocabulary.

This type of shading can effectively block the sunlight from the orthographic window with a small height angle. Therefore, it is mainly used for east-west glass curtain wall construction. Baffle-type sunshades can most effectively block the sunlight from the entire window. In order to take into account lighting and ventilation, this sunshade often needs to be moved and opened for proper adjustment. In this regard, different architects often have different approaches.
