Traditional architecture produces tons of garbage each year up to generate daily sewage up to 5.8 million cubic meters, the total social terminal building energy consumption ratio up to 27.5% ...... typical "two high-consumption" Construction extensive development mode also have led to one of "haze siege" around the culprit.
To this end, the Ministry of Housing has issued "green building programs of action" and other policies simultaneously support a number of green building industry. China's "Twelfth Five-Year" period will build green buildings 1 billion square meters, in 2015 the proportion of new buildings in the town reaches 20% of green building, sustainable development and the concept of circular economy by the blitz.
China's first listed company Steel Co., Ltd., Zhejiang Hangxiao single silver wood, said construction energy conservation has become essential. Steel structure represented by green building can effectively deal with energy conservation, the relationship between land, water, materials and environmental protection, will lay a governance PM2.5 of "warfare."
To the house but also to health
The third round of large-scale haze since the start of visits since October 23, in eastern China, Beijing, Tianjin, Northeast China, Huang-Huai and other places will reoccurrence of moderate to severe haze. Under the "ten surface haze V", 6 ministries recently issued "Atmospheric Pollution Prevention Plan of Action for the implementation of the assessment methods (for Trial Implementation) Regulations", will improve air quality objectives and tasks to be completed, the air pollution control in key task completion scores, respectively. Correspondingly, the background is that last year the country's total energy consumption was 3.76 billion tons of standard coal, building energy consumption is only approximately 1.1 billion tons of standard coal, a veritable pollution "big." Data show that China's existing buildings are about 95% belong to the high-energy buildings.
"To the house, but also to health." Hangxiao single silver wood chairman told the author that the construction market to pursue better quality, sustainable growth and investment patterns is the key. He said that steel and other green building "four sections of a green" advantages are clear, integrated steel factory building can be done, mechanization rate of more than 90%, the artificial reduction of 70% -80%, which is currently the main building green revolution grasper.
It is reported that Hangxiao "Steel beam combiner structure residential system" has been successfully applied for national patents, the technology will greatly enhance the one hand, buyers in the purchase of residential "room rate", while reducing residential construction period, will help the developers to slow credit pressure to shorten the cash flow; on the other hand, large-scale promotion of "Steel beam system", can speed up the construction industry, technology upgrades, the "disgraced" the building site into a "sophisticated, industrialization" of the modern workplace, so that construction workers turned into a technology-based "industrial workers."
Raised to 50% in 2020 according to "national new urbanization plan (2014-2020)", the urban proportion of green building accounted for new construction of two percent from 2012. Less made "gray house", create more "green house" is relevant enterprises to obtain more market share in the next important test for nearly 10 years.
In this case, steel "green house" on environmental issues related to the advantage of the industry has become a hot topic of discussion. "Steel buildings are four mind 'portfolio', can effectively deal with environmental problems, especially haze days." Vice president Hangxiao Sui told reporters.
First, in the construction of steel buildings needed for the construction cost were less than traditional building materials, can effectively reduce 35% of carbon emissions; secondly, dramatically reducing the cement, sand and other non-renewable resource consumption, and save about 30% of foundation material. Again, the assembly of steel building construction and integration decoration, overall reduce dust pollution caused by construction, reduce construction waste emissions; and finally dismantling and recycling during construction, including steel, steel, architectural glass, aluminum, including a large part of the material can be recycled.
Sui said, "Four record combined" to make about the construction of "green" execution paths form a closed loop cycle in steel buildings. "Hidden steel in construction, for the benefit of future generations."
