Are now advocating energy-saving, steel residential building known as the 21st century "green buildings." Compared with traditional concrete structure, with light weight, seismic performance, easy post-disaster rehabilitation, basic low cost, recyclable and renewable materials, energy conservation, provincial land, water and so on. However, this green building in our country such a big country of steel has been developed less than ideal. According to statistics, now, steel building construction industry in our country as a whole the proportion of less than 5%, while developed countries has already reached more than 50%.
In view of this situation, CPPCC member and professor at Wuhan Iron and Steel Group Technology Center to bring a senior engineer Yuan Weixia "promote steel housing, to reduce carbon emissions and promote sustainable development" proposal.
Yuan Weixia that the steel housing is a socio-economic development and scientific and technological progress in the construction of the product in line with housing industry and construction resources for sustainable development. In implementing the building of a conservation-oriented society, the implementation of low-carbon economy and reduce emissions today, and vigorously promote the steel housing, is very necessary, but also very urgent.
Steel housing with traditional concrete structure cost is roughly equal to the use of an area can be more than 5%%, but the building materials used in carbon emissions vary widely. According to Wuhan Steel Structure Engineering Co., Ltd. Changfeng cyber-Si analysis calculations indicate that steel housing, per square meter of steel consumption of 100 kg to 120 kg, using a variety of building materials, carbon emissions at 480 kg / square meters, while the concrete structure of the building materials for residential carbon emissions for 7406 kilograms / square meters. Housing using the process, due to its use of energy-saving design, the house of the thermal insulation effect is good. In the house, the removal of the final stage of dismantling of steel structures require less manpower and motivation, but also a large number of materials can be recycled.
Meanwhile, the steel structure is conducive to residential housing industry, namely, by industrial production methods, the construction of the houses to reduce energy consumption. According to statistics, if the real estate industry, housing industry the proportion of 10%%, annual reduction of sewage discharge will be about 10 times the amount of lake water to reduce the timber harvesting is equivalent to 9000 hectares of forests, conservation of electricity is equivalent to a Gezhouba Hydropower Station months of generating capacity.
Given a series of steel structure housing the advantages of Yuan Weixia recommended that the Government departments to take measures to promote its rapid development:
First, to focus on the development of residential steel TV towers, multi-layered and small high-rise housing, the residential dwelling size and use of space capabilities to meet the residential standards of well-off society in China. The second, related departments should intensify efforts to promote steel residential development, such as building affordable housing when the steel structure residential, commercial housing in the auction when the land required to build steel homes, residential construction on the steel structure of loans and tax aspects of of the support. Third, do a good job steel structure housing the pilot project, to create a number of steel structure housing the project of a point to face, the steady promotion of steel homes, and some innovation and development. Fourth, from the national level, organizations concentrate on carrying out the standard system and materials, steel frame residential building systems, building systems research. Fifth, step by step steel housing industry. Based on the use of existing technology, wall materials and to optimize the integration, to resolve steel structure housing three panels (floor, wall panels, interior wall board) problem is very important.
