According to the national Treasury's press office of the news, recently, the central government allocated northern heating area existing residential building heat metering and energy efficiency reformation capital of 1.7 billion yuan, plus the appropriations of $3.6 billion, before transferring funds of 5.3 billion yuan in 2012, major support for existing buildings energy conservation. Recently, the state department of housing and urban-rural development (hereinafter referred to as the "ministry") issued by the existing residential building energy-saving reform guide, only the northern heating areas in China town of existing residential building about 3.5 billion square meters need to reform. To this, vice President of China building materials circulation association qin of learning, points out that the news will not only is good for building energy conservation building materials market, will lead to the development of upstream and downstream related industries.
According to relevant data shows, at present, China's ten thousand yuan GDP energy consumption is three times as much as in the United States, the energy consumption of per square meter of real estate is three times as many developed countries. And according to the ministry, China's building energy consumption in the proportion of total energy consumption is very big, accounted for above 28%. According to the international experience and China's current building that can predict the level of development, in 2020, our country building energy consumption accounts for the proportion of the total energy consumption in the whole society will reach 35%, can be used for the first field. For how to implement energy saving renovation of existing buildings in the north of qin said, northern heating area is the key area of building energy efficiency in China, the annual heating heating will consume large amounts of energy, and emissions of carbon dioxide and other waste into the atmosphere, increased the concentration of greenhouse gases in the air. Due to the vast majority of existing buildings energy saving measures, palisade structure heat preservation and heat insulation performance is poor, can use the low system efficiency. About the personage inside course of study points out, winter heating and summer cooling energy consumption in China is now the common glass consumption dropped 50%.
Therefore, the retrofit of existing buildings in northern area, upgrade the heating heating system, make full use of ground source heat energy, is a major measure to promote building energy efficiency in north. Statistics from the ministry shows that if the current in the city do not accord with standard of energy saving energy saving renovation of existing buildings for BiaoMei can save about 35 million tons a year, if only for the existing buildings of nearly 2 billion square meters of large public buildings to conduct a comprehensive energy-saving reconstruction, can form the construction energy conservation industry chain of nearly 400 billion yuan.
