Recently, Hebei green building development regulations, the first local regulation to encourage the construction and purchase of green buildings, has been officially promulgated, which will be implemented from July 1, 2015.In fact, since last year, there has been a round of “subsidy wind” for green building all over the country. However, due to the lack of implementation of local laws and regulations, the promotion of green buildings is still slow. The promulgation of the regulations on the development of green buildings in Hebei Province is expected to accelerate the application and promotion of green buildings all over the country. 　　

 In fact, in order to demonstrate the determination to develop green buildings and promote energy conservation and environmental protection, since May 2014, Hebei , Hainan, Xiamen, Shenzhen, Hebei and other more than 10 regions have successively issued green building subsidy standards.　　

 Among them, the newly revised “Hebei provincial special fund management measures for building energy conservation and green building development” in April 2015 is more based on the change of the new version of “green building evaluation standard” for the award and compensation of green building evaluation identification project, from the original design logo star of construction project bidding project to the operation identification star level.Among them, the green building with three-star operation logo can get 50 yuan / square meter award.It is understood that many awards previously announced in other regions are less than 50 yuan per square meter, and a “subsidy wind” for green buildings is expected to be upgraded. 　　

 As a typical representative of green building, steel structure residence is just “wind outlet”.With the development and improvement of the independent steel structure housing technology system in China, the development of steel structure housing market can be described as “budding”.Especially in promoting the demand of green building and energy saving and emission reduction, the steel structure residence has the incomparable advantage of traditional concrete building. 　　

 But for a long time, the steel structure housing has not been widely used in the market.In this regard, some experts say that this is mainly caused by two reasons: one is the price problem, which traditionally considers that the cost of steel structure residence is much higher than that of concrete building; the other is the problem of household demand, and the previous technology of steel structure residence is not suitable for living.Due to the limitation of technology before, the structural form of steel structure residence is exposed beam and column mode, that is, there will be a protruding column and a protruding beam in the corner of the residence, which will have a certain impact on the comfort and aesthetics of the spatial pattern. 　　

 However, with the further implementation of relevant technology research and development, the promotion and application of steel structure housing market is expected to enter the “deep water area”.According to relevant people, a new structural system named “concrete-filled steel tubular shear wall structure” developed by a domestic steel structure company can not only shorten the construction period by half, including financing costs, management costs, labor costs, etc., but also be reduced due to the halving of construction period, and lower steel consumption, so as to significantly reduce the overall cost.At the same time, it also has the advantages of flexible arrangement of walls in shear wall structure according to the requirements of building functions, which meets the requirements of residents in terms of comfort and spatial pattern aesthetics. 　　

 For the application prospect of steel structure residence, relevant experts believe that the cost of the steel tube composite structure residential system developed this time is close to even lower than that of PC (prefabricated concrete), and the problem of exposed beam and column has been reasonably solved. The system is in line with the requirements of low-carbon and environmental protection housing industrialization.Therefore, as the steel structure enterprises have a major innovation breakthrough, it should be said that the steel structure housing industry has ushered in a very good opportunity, which is worth looking forward to. 　　

 Relevant experts believe that, with the help of various green construction subsidy policies, steel structure housing is just “tuyere”, and steel structure housing market space will gradually open.I believe that one belt, one road and one road, will surely open up a huge market for steel structure construction in Asian countries and the world. The new urbanization will also promote the long-term development of domestic steel structure construction market, especially steel structure housing.
