People's Daily Online, Beijing, May 24. "The construction of a green city is inseparable from the application of green building materials. The refinement, standardization, digitization and intelligence of the application of green building materials are the only way for the development of green building materials and green buildings." Recently, at the first China Green City Construction Forum and Green Building Materials Digital Science and Technology Innovation High-quality Development Summit, du Yun, chairman of the Green City Construction working Committee of the China Association for the Promotion of International Economic and technological Cooperation, said that only by speeding up the construction of green building materials 5G digital industrial park, using big data Internet technology and scientific and technological innovation to promote the green transformation of the traditional building materials industry, can we achieve the goal of carbon peak and carbon neutrality faster.

The outline of the 14th five-year Plan points out that we should promote the comprehensive green transformation of economic and social development and build a modernization of harmonious coexistence between man and nature. "Development of green buildings" is included.

In July 2020, the "Green Building Creation Action Plan" jointly issued by the Ministry of Housing and Urban-Rural Development, the National Development and Reform Commission and other seven departments clearly stated that by 2022, the proportion of green building area in new urban buildings will reach 70%. In this regard, Du Yun introduced to reporters that at present, my country is vigorously promoting the application of prefabricated buildings and green building materials, requiring the use of green building materials in new urban buildings to reach more than 40%, and the green building materials industry will usher in a broad space for development.

How to vigorously promote the development of green building materials industry? In Du Yun's view, on the one hand, it is necessary to develop safe, healthy, environmentally friendly, and excellent new building materials, and promote the certification and promotion of green building materials; on the other hand, it is necessary to promote the integration, systematization, and assembly of green building materials products. Let "green building materials go to the countryside" make new contributions to rural revitalization; on the last hand, it is necessary to create a new format for the digital development of the green building materials industry, build a systematic and perfect ecological chain of green building materials industry.

Yue Quanhua, former director of the Building Materials Department of the Materials Department of the Ministry of Industry and Information Technology, said that under the goal of achieving carbon neutrality, the "low carbon" of building materials is reflected in the goal of reducing greenhouse gas emissions, with low energy consumption, Based on low emissions, pay attention to the selection of green materials in the decoration process, as well as the recycling of products. Therefore, new building materials with low carbon and environmental protection are widely used in urbanization construction, urban renewal and transformation of old residential areas.

"Low carbon is a very important part of green development. Building a green and low-carbon circular development economic system with integrated urban and rural development and high-quality development has brought new development opportunities to the green building materials industry, and also put forward higher requirements on the quality, performance, function and security capabilities of materials." Yue Quanhua said that the new round of scientific and technological revolution represented by 5G, artificial intelligence, cloud computing, big data, new energy, digital economy and sharing economy has been further promoted, providing important support for the development of green building materials industry.

In addition, Yue Quanhua also pointed out that it is necessary to carry out research on the application of green building materials in pilot cities to promote the development of green buildings in high quality. He said, first of all, this will help to develop and strengthen the green building materials industry, accelerate the promotion of green buildings and passive ultra-low energy buildings, and help the construction sector to achieve carbon neutrality. Secondly, it is conducive to cultivating a complete domestic demand system and promoting a dynamic balance between high-quality supply and high-level demand for building materials. Finally, it is conducive to building a green, low-carbon and livable emerging city, widely forming a green production and lifestyle, and satisfying the people's yearning for a better life.

Sui Yinping, deputy director of the Emerging Industry Development Center of the National Development and Reform Commission, said that it is urgent to promote the green transformation of the traditional building materials industry. At present, the energy consumption of building materials in my country accounts for 39.5 of the national energy consumption. Green building materials are the material basis for building a green city. The integration of innovation and green development of the building materials industry is the fundamental guarantee for supporting the development of green cities.

"This is not only an important construction field and technology and people's livelihood field to promote the construction of green cities as the carrier and smooth the domestic cycle, but also a key link to implement the goal of carbon neutrality." Sui Yinping said.

Zeng Lingrong, president of the China Building Materials Industry Economic Research Association, told reporters that during the "14th Five-Year Plan" period, to promote the construction of green cities, we must firmly grasp the key driving force of industrial digitalization, and firmly grasp the assembly of green buildings and the parts of green building materials. The two key areas of the green building revolution are to vigorously develop green integrated manufacturing, intelligent construction, smart buildings, smart industrial parks, smart cities, and smart life, make it a new driving force for the development of green cities and green economy.
