Clean up the construction industry green wind market, the more violent now very hot.
Recently, the National Development and Reform Commission issued the "2015 recycling economy promotion plan" (hereinafter referred to as "plan"), including in particular the specific requirements for the construction of high energy consumption, construction, high pollution and other issues: promote energy conservation carbon reduction, increase of construction waste resource utilization and actively carry out MATERIALS iNNOVATION. The industry believes that, "plan" will further promote the development of the construction industry to "environmentally friendly" upgrading upgrade.
Data show that China has about 95% of existing buildings are high energy consumers. In this regard, the State Department counselor, former deputy director of the State Bureau of Building Materials Jiang Minglin believes that over-reliance on the "two high and one low" construction mode extensive mode of development, after decades of trial and error, the final to the end.
Bottom altitude dust haze over the sky, overlooking the depressed real estate, such as "urban disease" was the rule. However, there are numerous high-rise buildings, is really "squandering For beautiful eyes," how can "dial finally see the sunrise?" Insiders pointed out, so that the current urbanization "green up" and increase the proportion of green building, It would be a good way to simple.
Reporters recently located in Xiaoshan District of Hangzhou Qianjiang Century City talent special housing construction site to see, under construction Each individual buildings are nearly one hundred meters of the "big man." And these "big" and "member" in the local factories have a special order, "member" from the factory are produced according to specifications, assembled directly. Site clean and tidy, hear the roar of muck cars.
"Steel as the main representative of green building, resource consumption per square meter is about 800-1000 kg, only 1/3 of the energy of traditional architecture, and of which 50% is a renewable resource, thereby reducing the construction process on the environment destruction, extensive development to overcome the traditional architecture of the defect. "China's first steel housing industry base Hangxiao chairman told reporters single silver wood, steel research and development, quality control aspects of the site construction and other compliance with green building standards to achieve smart, green, low-carbon objectives.
"Steel buildings as the representative of green building already has multiple advantages, sustainable development concepts into the construction sector, will become the dominant trend in the construction industry." Professor of Architecture and Civil Engineering, Tianjin University, doctoral tutor Chen Zhihua told reporters.
Steel construction brings not only beneficial to improve the construction of environmental issues and sustainable cycle of economic model, but has been plagued by the problem of high cost has also received a significant breakthrough. In the reporter visited the talent special space projects, the use of new structural systems - Building 11, a combination of steel concrete beam shear wall structure particularly interesting.
"Steel concrete beam shear wall structure than the PC (prefabricated concrete) has obvious advantages, the cost can be reduced by 10% -20%." Staff Building 11 construction units Hangxiao's Road. Chen Zhihua that, after the new energy saving building materials, low energy consumption, long life, no pollution and other advantages, but the cost constraints, the market and technology that, although having little strides. And the powerful breakthrough in green technology system, raised the quality, go down the cost, large-scale application of more energy saving have a more broad prospects. "
Chen Zhihua said that with the "plan" as well as the implementation of air pollution "State 10", eliminate backward production capacity, strengthen energy conservation, building a series of policies to promote ecological civilization, and accompanied by the relative strengths of enterprise technology innovation and cost management, steel development sail is the time.
