Construction is one of the three traditional energy-consuming industries, consumes the energy of the whole society of nearly 30%. High energy consumption, high emissions, high pollution has been a trial of domestic steel prices, serious excess capacity directly affects the survival of businesses. Can walk on two legs, allow industry to become "green" does not contradict development and ecological protection industries; and "green" industries to develop green building industries such as steel?
Connection of steel structure building industry and steel industry transformation and upgrading of the "Green House". As the main representative of green building, the advantages of steel buildings with steel recovery 90%, once a large number of construction, steel structure construction will become the "steel storage". Meanwhile, steelmakers can also take green energy-saving ride. After calculation, if the construction methods of steel structure in China's popularization of the industrialization of construction waste will be reduced by about 83%, building energy efficiency is more than 50%.
Steel as a green building, throughout the full life cycle "reduction, reuse, recycling, reduction of priority" of circular economy principles can maximize saving resources, protecting the environment and reducing pollution. With the steel industry's "improving the efficiency of steel products, promote the reduction of the life cycle of steel products and green" goals coincide.
At present, our country steel structure super high and large span spatial structures, industrial plants and other areas have been widely applied, in housing, urban development and other applications with a broad space. It would be expected that shipped to the site in the future more will not fragmented steel, concrete, insulation Board, but a piece of the wall panels, stairs and other "parts"; workers in the machinery of cooperation of these "parts" assembled into a residential ……  
In strong support of the State, the green building industry gradually achieved nothing, changed from weak to strong. New this year since the implementation of the evaluation of green building standards, green building in China is showing strong growth momentum. According to statistics, China's total ranked 3194 green building assessment identifies the project, doubling the number from a year with total floor area of reach 360 million square meters. Currently, 287 prefecture-level cities across the country, put forward low carbon eco-city construction in the city has reached 280, proportion of urban green building new building this year is expected to be in 2012 from 2% to 20%.
