As in previous years the International Green Building and Energy Conservation Conference is different in this year's "green building, green building materials and indoor environment optimization" sub-forum, a new discussion on the contents of green building materials not covered in previous years have attracted much attention, especially For green building materials green building development in the basic role of the development of China's construction industry as well as the importance of the role of the industry conducted lectures for participants elaborated on a deep understanding of green building materials. "Green buildings need the support of new building materials. Did not use the development of new building materials, green building has become a river without water, without trees of 'castles in the air'." Trodat Group Executive Vice President Zhang Jianping said.

Green building materials is the basis for green buildings

Chinese Society for Urban Studies Green Building Materials Research Institute Li Jiangong that green building green building materials is an important foundation for green building is bound around the use of green building materials in full swing, the emergence of new green building materials throughout the construction industry will inevitably lead to revolution .

In China's "green building rating standards" Although there is no "green building" in clear words and expressions, but it clearly will "adopt intensive production of building materials, components and parts, reducing on-site processing," green building evaluation into control entry, the "use good durability of construction materials, such as high-strength steel, high-performance concrete, high performance concrete admixture" and "will be construction, old building demolition and site cleanup of solid waste can be recycled use of renewable and recyclable materials recycling and reuse of separation "and other content on the general term, but will be" high-performance, low material consumption, durability, good new building structures "is as green building evaluation preferences .

All these specific standards achieved without green building materials. A sand-stone, a bar, a component ...... Though small, it determines whether the building "green" and can successfully get the green building star logo.

Zhang Jianping, said: "Green building is the result of rigorous testing national testing agencies do not release formaldehyde, benzene, ammonia and other harmful substances, and radioactive materials, but also in the production process does not produce polluting waste water, waste gas, waste, are completely low carbon environmentally friendly building materials, is the ideal choice for national green building material. "

Early this year, the National Development and Reform Commission, the Ministry of Housing and Urban Construction jointly issued the "Green Building Action Plan" will vigorously develop the green building materials green building our country's development as one of the tasks of the ten, clear requirements to local conditions, local materials, combined with local climate characteristics and resource endowment, to develop safe durable, energy saving, convenient construction of green building materials, and to speed up the development of better building insulation fireproof insulation systems and materials, and sintered hollow products, aerated concrete products, multifunction integration of wall materials, integrated roofing, low-E glass, bridge insulated windows, shading systems, high-performance concrete, high strength steel and other green building materials.

Not long ago, the Ministry of Housing and Urban-Rural Development has issued a "" second five "green building and green eco-city development plan", pointed to a number of key laboratories, engineering technology innovation center, focusing on green building, new materials, new technology development; building green building materials, products, equipment and other industrial base, promoting high technology content, good economic returns of scale green building materials, lead to green building materials, energy saving and renewable energy industries.

It is reported that, in order to promote research and development of green building materials, Chinese Society for Urban Studies at Trodat Landao New Material Research Institute inaugurated a green building, green building materials for promoting the development, design and production base.

Recycling of construction waste to green building materials

Statistics show that China's emissions from large construction waste, construction waste recycling rate is low, less than 5%, and the EU countries as well as Japan, South Korea has a big gap. At present, China's annual demolish buildings generated more than 250 million tons of solid waste, solid waste generated new buildings about 150 million tons, for a total of about 400 million tons. Construction waste has accounted for 30% of total municipal waste to 40%, ranking second in municipal waste has serious harm to the urban construction and environment, to become a major social nuisance.

In the "" second five "green building and green eco-city development plan", the proportion of building materials and waste recycling as a green eco-city index system in a control indicator. "Green Action Plan" that should speed up construction waste recycling technology and equipment research and development promotion, preparation of construction waste utilization technology standards, to carry out construction waste recycling demonstrations, study the establishment of construction waste recycled product labeling system.

All kinds of waste can be recycled into a useful material is construction of a conservation-oriented society needs. In the construction of green buildings have been processed using a variety of waste, recycling of wastes, green building is not only a symbol, but also the green building energy consumption for the whole community contribution.

Comprehensive utilization of waste has been the industry's struggle topic. Midtown Branch Green Building Materials Research Institute, Trodat Group CEO Yang history introduction, Midtown Branch Green Building Materials Research Institute research to fill our use of waste, construction waste, gangue polishing turns green building materials, blank, not only for national construction waste to use a major breakthrough, but also solve the problems of urban development in China junk "Besieged City" problem.

Housing industry calls for green building materials

Housing industry has become the future development of the construction industry sent to. Residential green building materials is a necessary requirement for the development of industry, while the housing industry calls for green building materials, on the contrary to promote the green building industry.

Jianping that the housing industry in the production and business model saving time, reducing costs, saving period. Building materials and products are the basic material elements of residential construction. Old industrial building with green building standards far are inconsistent with the development of green building concept, the housing industry for new materials and new products from specifications, quality and performance will make new demands. To improve the ability of components and parts for assembly and construction quality speed, components, fittings must be designed to improve plant production style fine, practical, improve size, accuracy specifications, materials to be used texture density, easy processing, easy modern transport, easy forming new building materials, but also an inevitable requirement of new building materials have energy saving, environmental protection, health care functions to achieve a modern residential green building indicators. This requires building materials industry must make the appropriate technology research and development, equipment modification, according to market demand constantly adjust the industrial structure and product mix, improve building materials production technology and management, improve product quality and technical content, the crude product to fine processing semi-finished and finished products direction.
