Europe says green building is an ecological building or sustainable building. The United States called the green building. China to the definition of green building is "refers to the in the construction of the entire life cycle, maximum conservation of resources (energy, land, water, wood), protect the environment and reduce pollution, provide health, application and efficient use of space for people, and the natural harmonious coexistence of building."
Academician of the Chinese Academy of engineering, Tongji University Professor Shen Zuyan said: "the construction industry in our country in recent years has been energy, materials, water and other resources the use of major , development to promote the application of steel structure in full compliance with national efforts to promote the initiative for the establishment of a conservation minded society, it is in accord with the requirements of sustainable development of construction industry put forward by former national." Shen Zuyan for the steel structure building summed up the "light, fast, good, province," the four major characteristics. Light - steel structure building with light weight. The weight of the steel structure housing is about 50% of the reinforced concrete house, the use of the area is about 4% higher than that of the reinforced concrete. Fast - the industrialization of steel structure building is high, and the construction period is short. Under the same conditions, the steel structure and the reinforced concrete structure construction period, compared with the steel structure is reinforced concrete structure 1/3~1/2. Good - good steel structure, high reliability. In the past earthquakes, the steel structure is the lightest structure, and has been recognized as the most suitable structure for the earthquake resistant area, especially the strong earthquake zone. Province -- simple from currently material prices, steel structure than the cost of the concrete structure to high, but steel structure than the concrete structure construction speed to about 50% faster. This will save a lot of time cost and the whole weight of the house also concrete structure are 50% lighter than the above, such foundation treatment, and the amount of transportation costs will decline. Construction is a system engineering, including design, manufacturing, transportation, installation, maintenance and management, and many other aspects, therefore, from the overall perspective, the steel structure more province". In addition, the steel has the characteristics that can be recycled, compared with the current use of other building materials, which is the most conducive to energy saving, section materials, water saving and land. Shen Zuyan to the steel structure be concise and to the point summary, and characteristics of green building is so.
Zhejiang Steel Structure Industry Association, Hanjia Design Group Co., Ltd. chief engineer fanghongjiang combined with the characteristics of steel structure, with the theme of green building proposed "zero resources, zero energy consumption, zero emission, zero pollution, Zero site, zero distance" concept of architectural design and the use of in the current domestic built the largest steel structure residential estate in -- million County mostly city residential project. As the design, most million city residential project manager, Party Hongqiang is very optimistic about the steel structure construction industrialization. In million County mostly city residential project design and construction process, led to give full play to the Taoxing structure of steel structure building system can moderate change, non load bearing parts can be replaced and steel can be recycled three major advantages, in accordance with the concept of green building design, with six zero design standards, the establishment of from the planning, design, construction, use and dismantling of the construction life cycle development and construction of the new model, the design and construction of a new generation of meet the industrialization, standardization and industrialization of the production of modern steel structure residential building products. Million County mostly city model for accelerating residential industrialization, change the traditional housing production, promote energy saving and green low carbon environmental protection building up to the important role of demonstration and guidance.
