Advantages of external shading in modern architecture

Usually we all know that the building shading system is divided into indoor shading, outdoor shading two ways, China's traditional house shading is generally indoor shading, that is, we usually call the curtain, is made of textile curtains, because there is a decorative function called fabric. In addition, as people pay attention to the environmental protection of the home, aluminum alloy blinds have been loved by indoor home decoration as an inner shade. But from the effect of shading energy saving, in fact, outdoor shading is far more efficient and more scientific than indoor shading.

Indoor shading places equal emphasis on shading and decoration. Generally, it is divided into two types: window decoration and fabric. At this stage, there are quite a lot of varieties and colors of indoor shading in our country, and the shading effect is also different. However, whether it is venetian blinds, roller blinds or fabric, etc., it is treated after sunlight enters the room, forming a heat island effect between curtains and glass. Curtains have no sealing effect indoors, and heat is easy to spread indoors, in order to reduce the heat, the only way to reduce the heat is to use air conditioning for refrigeration. Indoor products like this are generally sunshaded and not insulated. Therefore, this is the reason why it is also very hot when there is no sunlight in the man's city room at night (of course, this has a lot to do with wall insulation). The use of outdoor such a system is to block the heat in the outdoor, so that the outdoor air convection faster, so it will not form a heat island effect, outdoor shading materials should be used quickly heat dissipation materials, such as aluminum alloy materials and so on.

According to research, a building with 32% direct light, the heat obtained from the sun accounts for about 28% of the total heat absorbed. If internal shading is used, 50% of this heat load can be reduced, while external shading can reduce 75% of this heat load. Therefore, the use of outdoor can greatly reduce the effect of heat load and greatly reduce the indoor temperature.

There are also many products to choose from for outdoor sunshade, including outdoor replica, aluminum alloy, fabric, roller shutter, etc. There are also outdoor sunshades, which have better air circulation, but they are not suitable for installation on the outer walls of high-rise buildings. Outdoor louvers and outdoor roller shutter are more suitable for installation outside the windows of high-rise buildings. Outdoor shading because the curtains are installed outside the window, most of the sunlight and heat are blocked outdoors, which greatly reduces the indoor temperature, so the outdoor shading method can play a very energy-saving role. By comparing the indoor, 80% of the heat still enters the room through the glass, while the outdoor sunshade only has less than 40% of the heat entering the room, so the energy-saving effect of the internal sunshade is far less than that of the external sunshade.

In addition, compared with the external shading and internal shading, there are the following advantages:

First: the inner sunshade through some textiles, PVC materials or paint aluminum alloy materials, how much there are some free formaldehyde, there is a certain degree of pollution to the indoor air. The use of outdoor shading on the indoor air without any pollution.

Second: because there is already outdoor shading, as long as the indoor decoration of some very beautiful textiles, because there is no direct sun, so textiles will not fade, will not age, indoor curtains because do not consider the problem of shading two will not be too cumbersome, greatly saving the indoor space.

Third: reduce energy consumption. The use of external sunshade can be installed in a unified way with the supporting buildings of the house. The factory assembly line greatly reduces the loss of materials and the pollution to the environment than the production of curtains of each household. It can make the development of curtain sunshade industry rise to a higher level, and also integrate the low-carbon and energy-saving policies of the National Tenth Five-Year Plan.

Fourth: can be used to beautify the building. Indoor shading due to the different choices of curtains for each household, each building was originally very beautiful. After the curtains were installed, all kinds of curtains were disorganized and unsightly, which greatly reduced the beauty of the city. After the outdoor shading was installed, the external wall image of the building was all unified and the offline feeling was very strong. Even if the household was decorated with Xinghua curtains, it would not have any influence on the attempt. From the above, we can know that the energy-saving effect of outdoor shading is far greater than that of indoor shading, which is incomparable. I suggest that I should introduce effective policies for outdoor shading related industries as soon as possible and regard it as a mandatory project for building shading and energy-saving, so as to achieve our goal of low carbon and energy saving faster. Modern home pays attention to the external decoration of the building and the internal shading and environmental protection, which is undoubtedly one of the reasons why the external shading products can be widely used in the decoration of various buildings.
