subject: Cppcc National Committee Members Advocated Building Energy Concern Ground Source Heat Pump [print this page] Core Tip: They found through research, internal and external heat exchange from the lower external wall insulation, to cut off the bridge with a new type of hot and cold frames, to the low radiation, high thermal insulation performance of insulating glass, to be able to block 80% of the sun in wall of the roller blind, to make full use of geothermal energy to maintain constant temperature room Ground Source Heat Pump This series the use of energy-saving measures, to enable some projects Building energy efficiency Rate of 85%.
"From the existing building to see, 95% are high energy consumers. If the future situation does not improve once the construction of housing a large number of high-energy, short-term reform is difficult. The best way to ensure that the transition to the low economic carbon future, the need to avoid today's investment decisions leading to high carbon emissions lock. "
The eve of the Environmental Protection Wu Xiaoqing, vice minister of members of the remarks, directed at building energy efficiency industry, "ceiling." In fact, the construction industry, energy conservation is a pressing issue. The "two sessions", on the development of green building, promote building energy efficiency proposals and statements increase in number, members from different angles for the construction industry save energy, sustainable development "of the essay."
Reporter has learned that the rapid development of China's construction industry has mounted a major energy consumer in the blacklist, some experts do not hesitate to call it Energy "Black hole." According to statistics, China's building energy consumption, including heating, air conditioning, ventilation, lighting, hot water, Home Appliances The total energy consumption, etc., more than the total primary energy consumption is 1 / 4 to about 30%, the highest energy first. With accelerating urbanization in China, this proportion will show a rapid growth trend. Not only that, the building has increasingly become the city's carbon emissions, "big." It is estimated that 60% of urban carbon emissions from energy consumption to maintain the building functions, while traffic Car Account for only about 30%.
KMT Central Committee called for in the proposal as soon as possible the development of green housing standards, land auction, construction planning, construction, building inspection and acceptance of a clear energy saving aspects, the application of the housing industry and energy-saving technologies, and in accordance with the relevant standard residential projects, encourage the types of industries included in directory, to promote their priority. In addition, should give full play to urban planning of the project development guide for the application of the housing industry and energy-saving technology of the project to provide public supporting facilities.
Population, Resources and Environment Committee of the CPPCC National Committee Wang Shao-Jie, deputy director of members in his speech should be made to speed up the administrative legislation, the promotion of building energy conservation from the call into the mandatory sexual behavior. He suggested that "12 5" planning should start for the new building construction and transformation of low-carbon ratio of the amount required to develop and sub-annual implementation plan. While strengthening the pilot and demonstration work to ensure energy saving Project Quality.
Construction Central in the proposal that the goal is to achieve green building energy, water, land, materials, protect the environment and reduce pollution, more attention to people's comfort and the harmony between man and nature, represents the modern building development. They found through research, internal and external heat exchange from the lower external wall insulation, to cut off the bridge with a new type of hot and cold frames, to the low radiation, high thermal insulation performance of insulating glass, to be able to block 80% of the sun on the wall of roller blind, to make full use of geothermal energy to keep the room temperature of the ground source heat pump, the use of this series of energy-saving measures can make some of the projects of building energy saving rate of 85%.
Compared with developed countries, the pace of China's green building is indeed long overdue. It is understood that, as early as 80 years in the 20th century, construction of green buildings in developed countries have reached a consensus. Such as the German real estate industry has focused on building the overall energy balance, the continuous development of building energy structure can be adjusted to reduce building energy consumption of new technologies. In China, according to June 1, 2006 the formal implementation of "green building rating" standards, from the national point of view, meet green building standards are only a dozen.
Not only started late in China Building Energy Efficiency, energy waste problem more serious. Population, Resources and Environment Committee of the CPPCC National Committee Wang Shao-Jie, deputy director pointed out that the current process of building high energy consumption, there is a lot of construction due to the irrational structure of materials caused by improper use of high energy consumption and emissions issues. The data show that compared with developed countries, China's construction steel consumption to 10% higher to 25% per 1 cubic meter of concrete mixing cement consumption to more than 80 kg; sanitary wares for more than 30% higher water consumption, while the sewage collection was only 25% in developed countries. At the same time, China's building energy efficiency is very low, the unit energy consumption of building the same climatic conditions than the 2 to 3 times higher than developed countries.
In the field of green building, low-carbon housing development has also been praised. Currently, about 50% of the world of residential development in China. Domestic production is energy-hungry China in residential construction and energy consumption during use accounts for 30% of total energy consumption of the community, building materials, energy consumption accounted for 16.7%. In this regard, Shandong Institute of Economics Institute of Real Estate and Economic Guo Songhai members felt that the housing industry to promote the industrial production of low carbon housing, through a large number of new technologies, new materials, new processes, new equipment to promote and increase the scientific and technological progress of the residential the contribution rate and the housing construction industry labor productivity, thereby improving the overall housing Environmental protection Energy level.
