Large building daylighting roof shading solutions
2024-07-22
According to the China Building Shading Materials Association, large-scale construction sites are mostly public buildings or commercial buildings, and daylighting roof structures are often used to improve the natural lighting rate and permeability of buildings. While increasing the natural lighting, permeability and beauty, it also increases the adverse effects of light discomfort and rapid indoor warming. In order to solve this contradiction, it is necessary to set up reasonable shading facilities for the lighting roof.
Glass lighting roof can generally be set from the outside of the lighting roof shading and from the inside of the lighting roof shading two ways, referred to as external shading and internal shading. According to the statistics of the lighting roof shading project investigated by the China Building Shading Materials Association for many years, the application of internal shading is more than that of external shading. Although the effect of internal shading is far less than that of external shading, the field of domestic architectural shading is still dominated by the application of indoor shading. The association pointed out that vigorously promoting building external shading and achieving better building energy-saving effects is also the direction that the building shading industry should strive.
Shuttle-shaped louvers or flat louvers are generally used for shading outside the lighting roof. Shuttle-shaped louvers outdoor louvers can effectively block sunlight radiation, while protecting the glass lighting roof, which has a good heat insulation effect. The main thing is that outdoor louvers can realize fine adjustment of sunlight through the rotation of the blades, so as to better control shading and lighting, and provide a comfortable indoor light environment and temperature.
The inner side of the lighting roof is generally set with electric ceiling curtains or electric louvers.
Electric canopy curtain is a common sunshade form for daylighting roof shading. Generally, FSS electric canopy curtain and FCS electric canopy curtain are mostly used. FSS electric canopy curtain belongs to rolling electric canopy curtain. Open the fabric in a tight state, and fold the fabric and curl it to one end of the round tube. FCS electric ceiling curtain is a folding electric ceiling curtain. The fabric is wavy when opened, and folds to one place when retracted. From the shading effect, there is no obvious difference between the two. However, in terms of indoor decoration and beauty, FSS electric ceiling curtain is flat and beautiful than FCS electric ceiling curtain, so FSS electric ceiling curtain has become a widely used type of electric ceiling curtain.
