The prefabricated building refers to the construction in the form of standardized production, parts separation, prefabrication in the factory, integration of insulation and decoration in the production of prefabricated parts, and transportation to the construction site for assembly based on modular design and modern management means. Promoting the modernization of the construction industry and vigorously developing prefabricated buildings are conducive to achieving energy conservation, emission reduction and resource recycling, promoting green and safe construction, improving the quality of residential projects, and improving the living environment. Compared with traditional buildings, prefabricated buildings can reduce 40% water consumption, 40% steel loss, 60% wood loss and 60% construction waste.
It is proposed to actively promote the application of passive low energy consumption green building technology. From July 1, 2017, among all new construction projects in the city Public buildings The project and industrial building project fully adopt prefabricated buildings. All counties and districts should build steel structure residential demonstration communities, gradually expand the scope of use, and increase the proportion of prefabricated buildings in new buildings year by year. Encourage enterprises to adopt prefabricated construction in commercial residential development projects, and give priority to the use of steel structure and passive low-energy green building technology.
We will support and promote the modernization of the construction industry and the development of prefabricated buildings in terms of area awards, financial awards and subsidies, and construction land. For commercial residential projects with industrialized construction and prefabricated assembly rate of more than 30% or passive low energy green building technology, when going through planning approval procedures, the building area of the prefabricated part of the exterior wall or the insulation layer of the exterior wall (not more than 3% of the planned area of prefabricated buildings) may not be included in the plot ratio of the transaction plot. The municipal, county and district governments have established special funds to subsidize prefabricated housing or passive low energy green building technology projects. The newly started urban shantytown reconstruction and commercial housing projects will be subsidized by the municipal government with a subsidy of 100 yuan per square meter, and those self built by rural villagers will be subsidized by the county/district government with a subsidy period of 5 years. The land department will give priority to land use for commercial residential projects that actively apply for the construction of building industrialization technology, and the prefabricated assembly rate reaches more than 30%.
