Green development is an important development theme of building materials industry in the future. Green building materials is an important force in the transformation and upgrading of the building materials industry. So what is green building materials? What is green building?

The so-called green building materials are building materials products that can meet the functional requirements of green buildings, reduce the consumption of natural resources and reduce the impact on the environment in the whole life cycle, and have the characteristics of "energy saving and emission reduction, safety and convenience and recyclability". Green building materials.

The green building is a building that saves resources, protects the environment and reduces pollution to the maximum extent, provides people with healthy, applicable and efficient use of space, and coexists harmoniously with nature during the whole life of the building.

　Connotation and Requirements of Green Building

At present, there are four major requirements for the development of green buildings: first, materials and products that can enhance the thermal insulation effect of buildings. Second, materials and products that can reduce the weight of buildings and save materials. Third, materials and products that can promote the efficient use of water resources. Fourth, materials and products that do not pollute the environment inside and outside the building.

At present, housing consumption is being upgraded, and high-quality houses, including green houses, are becoming a common pursuit of people's housing consumption. And high-quality housing has its own connotation: first of all, it has better safety and reliability. Buildings have good waterproof, fire prevention, durability, weather resistance and can resist natural disasters such as earthquakes, strong typhoons and other properties. Secondly, it has better green functions. The building has good energy-saving, land-saving, material-saving, and water-saving effects, and does not produce toxic and harmful gases, does not contain pathogenic substances, does not precipitate heavy metals, and has no radioactivity. Third, it has the comfort function that meets the requirements of human habitation, and the building has the adjustment function of temperature, humidity and air freshness that can make the human body feel comfortable. Fourth, it is beautiful. Buildings from the appearance, shape, structure, layout, color and other aspects can give people the enjoyment of beauty. Fifth, it has more convenient functions. The building's power supply, water supply, gas supply and communication facilities are complete and more humane.

Not only that, in recent years, national policies have also become an important driving force for the development of green building materials and green buildings.

On January 1, 2013, the General Office of the State Council forwarded the green building action plan of the Development and Reform Commission and the Ministry of Housing and Urban-Rural Development to the State Council [2013] No. 1. Subsequently, on April 25, 2015, the Central Committee of the Communist Party of China and the State Council issued the "Opinions on Accelerating the Construction of Ecological Civilization", and once again proposed to vigorously develop green buildings.

With the acceleration of the process of a well-off society in an all-round way, according to the relevant requirements of ecological civilization construction, all new buildings in China will be built in accordance with the standards of green buildings in the future. It is estimated that the annual new building area during the 13th five-year Plan period will still be more than 2 billion square meters. In addition, at least 50% of the existing buildings of about 60 billion square meters in China need to be gradually transformed according to the standards of green buildings.

　Five trends of green building materials

The first is the trend of building parts.

In order to meet people's new requirements and expectations in terms of living environment and conditions, the construction industry will develop in the direction of modern construction industry. The modern construction industry is composed of industrialization, greening and intelligence, among which industrialization is the foundation and premise. The so-called construction industrialization refers to the factorization of product production and the assembly of construction.

Building parts are the product of building industrialization, which refers to the construction products that are assembled by different materials under the conditions of industrial production and can meet the functional requirements of buildings. Such as by purpose, mainly including building structures, wall products, roofing products, doors and windows products. Such as by function, mainly including: thermal insulation products, waterproof products, fire products, sound insulation products, sealing products, decorative products, water supply and drainage pipe fittings, bonding, cross-linking products and components.

The development of building parts is not only conducive to improving the efficiency of building construction, but also conducive to ensuring the quality of buildings, and making building materials products better meet the requirements of building functions.

The second is the agglomeration trend

Industrial agglomeration refers to a relatively concentrated and functional industrial development mode formed by the whole industrial chain from raw material supply to product transaction according to a certain division of labor and cooperation. Through industrial agglomeration can make the professional division of labor to the most reasonable degree, so as to achieve the ultimate product quality. At the same time, industrial agglomeration can make all links of the industrial chain achieve seamless docking, thereby improving the efficiency of collaboration between various links, reducing intra-industry transaction costs, and enhancing the competitiveness of products in the agglomeration area as a whole. And the green building materials industry chain is long, suitable for the development of industrial agglomeration.

The third is the green trend

Green building materials themselves also have the problem of green development. The content of green development mainly includes energy conservation, emission reduction and comprehensive utilization of resources, that is, to minimize the consumption of natural resources and reduce the impact on the environment, thereby reducing production costs and achieving environmental protection. protection.

The fourth is the trend of flexibility

The current era has entered an era of individuality, and housing consumption is no exception. In order to meet the increasing personalized needs of people in housing consumption, building materials product suppliers, especially decorative building materials product suppliers, are required to have the ability to manufacture flexibly.

The fifth is the intelligent trend

This includes: the intelligence of the product manufacturing process; the intelligence of the product; the information interconnection and resource sharing of the whole industry chain.
