China Business Intelligence Network News: Building shading refers to the installation of shading facilities on buildings that have the function of blocking or adjusting sunlight entering indoors. The key application position of building shading lies in building window holes. Building window holes are the only way for building natural lighting and the main way for buildings to directly obtain solar radiant heat in winter. It is also an important factor in the size of building air conditioning load in summer. Therefore, building window holes and auxiliary facilities The design and manufacturing of the building have a very important position in architectural design and indoor environment control technology and systems. The building shading industry includes the production of building shading main materials, parts and products, building shading product assembly and sales, building shading scientific research, engineering design, construction and installation, building shading products and engineering testing, acceptance and other related links.

　　The main shading products used in modern building shading can be divided into functional shading products and traditional shading products according to their application functions.

Policies are good for the development of the building shading industry

　　 With economic development, China has become a recognized energy-consuming country, and building energy conservation is imminent. As one of the main building energy saving methods, building shading plays a key role in the realization of building energy saving. In recent years, the country has successively issued a number of laws, regulations and policies to support and promote the development of the building sunshade industry.

The scale of the building sunshade industry continues to grow

　　 With the rapid development of the national economy and the rapid improvement of people's living standards, the demand for the building sunshade industry is increasing. According to the statistics of the Building Shading Industry Association, the total sales of the building shading industry in 2016 was about 463.02 billion yuan, of which the export value was about 13.6 billion yuan; the total sales in 2017 reached about 508.53 billion yuan, of which the export value was about 15.1 billion yuan; Ushered in steady growth, the total sales amounted to approximately 569.32 billion yuan, of which 18 billion yuan was exported. It is estimated that by 2020, the industry's total sales will be about 637.3 billion yuan and the export value will be about 20 billion yuan.

At present, the structure of domestic solar shading products has been fully transformed and upgraded from mid-to-low-end to mid-to-high-end. Consumer needs at different levels have been met, and a large number of powerful companies have been formed in the solar shading industry clusters in Zhejiang, Jiangsu, Beijing, Shanghai, Guangdong, and Shandong. Grow fast and start to be in line with international standards.

Development prospects of the building sunshade industry

　　 1. The standard system is gradually established, and many parties will work together to promote industry standard work in the future

　　 At present, my country's building sunshade industry standard system is basically established. As of the end of 2019, the Ministry of Housing and Urban-Rural Development has issued more than 30 reference standards for the sunshade industry, covering terminology standards, general requirements, product standards, method standards and engineering technical specifications. Under the joint efforts of the Ministry of Housing and Urban-Rural Development, China Building Shading Industry Association and other parties, progress has been made in the formulation of national standards, industry standards and group standards. The national standard "General Technical Requirements for Building Indoor Window Decorations" edited by the Building Shading Materials Branch held a working meeting to solicit industry opinions; engineering construction recommended standards "Technical Specifications for Intelligent Building Shading" and "Technical Specifications for Construction and Installation Services of Building Shading Products" Other group standards are forming a standard compilation group; "Built-in sun-shading hollow glass products", "Metal blinds for building sunshades", "General technical requirements for building sunshades", "Technical requirements for building ventilation shutters" and many other industry recommendations are being prepared Formulated and launched one after another. On December 14, 2019, the 7th National Building Shading Industry Annual Conference was grandly held, emphasizing that standardization should lead the development of the industry, adhere to the value orientation of standardization, and jointly shape the industry standardization system. With the gradual improvement of the standard system, it will surely promote the continuous improvement of the quality of building sunshade products, and help my country's building energy conservation and green building development.

　　2. Product structure and technical functions are significantly optimized, and multiple industrial clusters will gradually be formed

　　 With the continuous development of the national economy, people’s living standards continue to improve, and consumers’ awareness of green, energy-saving and environmental protection is increasing, and energy-saving and environmentally-friendly products have become the focus of most people’s attention. The structure of building sunshade products has also developed from mid- and low-end products to mid- and high-end products to meet consumer demand at different levels. Under the general trend of energy conservation and environmental protection, more and more building smart sunshade products are active in the market, and with the integration of smart technology, they have become an indispensable part of smart homes.

　　 In terms of technology, the skinning, diversification, and architectural integration design of modern building shading are the three main development directions. Since the building skin is no longer a simple division of internal and external spaces, its functions have become increasingly complex, such as shading, lighting, ventilation, and moisture retention. In terms of architectural integration, both the overall sunshade and the traditional sunshade for daylighting have their advantages and disadvantages. They need to be selected according to different needs to achieve a balance between use and energy saving.

　　 In addition, the sunshade industry has become an important industry for large-scale industrial production. At present, my country has gradually formed the building sunshade industry clusters in Zhejiang, Jiangsu, Beijing, Shanghai, Guangdong, Shandong, etc. A large number of powerful companies have grown rapidly, and gradually entered foreign markets, accelerating the pace of integration with the world.
