In recent days, the cold Northeast China to zero degrees Celsius, but lived in Changchun City, Jilin province, Li guiling felt the room temperature is not like in previous years so low. As a Government "warm house" beneficiaries, she lives in old buildings by increasing the insulation, thermal insulation effect is greatly enhanced.
"Outer wall to affix a 6 cm thick polystyrene Board, window by aluminum alloy replaced with plastic, the House also added heat meter. At this time, the room temperature in the past to 10 degrees as well, this year reaching 14 degrees. This hasn't heating, if heating, firing the same coal this year certainly higher than last year at room temperature. "Li guiling said.
With 13 million population of China, through various methods seek to service people's livelihood and energy-saving emission reduction between the search for new balance.
"One to the North of the heating period we have headaches, on the one hand, coal, electricity and natural gas are tense, not enough energy; on the other hand, some people are not satisfied, always complaining about the temperature of the House to themselves on not paying the heating fee but no access to proper temperature, suffer. "Engaged in a decade heating of Jilin tongxin thermal Group President arch man said," and this year is different, there is a solid feel. ”
It is understood that the industrial, transport and construction is the most important areas of the three energy consumption, building energy consumption accounts for about one-third of Community consumption.
Since the 1980s, the Chinese Government began to try to promote energy-efficient buildings. Jilin province as an example, energy saving design standards by 30 per cent to 65 per cent. Currently, there are buildings in Jilin province, energy-saving housing accounted for 40 percent, still a 60 per cent of non-energy-efficient buildings.
These non-energy-saving building is troubled by the North heating effect of a universal problem. Tianjin University has China North town winter heating calculation done simulation showed that, in a heating period, temperature increase of 1 ° c, standard coal consumption 4.79 kg/m2.
"Non-energy-saving housing room temperature increase of 1 ° c, annual energy consumption to many 9.889 million tons of standard coal. "Changchun accommodation group co., Ltd. Chairman of the Board, high baoxiang as standard coal calculation of the market, we should spend $ 8118, not only wastes energy, and increases carbon dioxide and dust emissions. "Therefore, the old houses do insulation, improve the old House of cold warm standard is very necessary."
In recent years, the Chinese Government in the North of existing buildings for energy saving, energy-saving ideas for expanding the area of a large number of measures, and achieved remarkable results.
Changchun Yatai Garden district heating room always has up to 16 ° c. 2009 on the community for energy saving, the heating period generally to residents at room temperature of 18 °-20 ° c, heat the water temperature but the company from 49 ° c down to 43 ° c, 40% energy savings.
Jilin tonghua County 2009 national awards funds for the whole County, 449 buildings all for energy saving. The County only started 2 heating boilers will meet the past need 4 heating boilers in order to satisfy the amount of heat supply, the entire heating period can save raw coal 2 million tons, the total value of $ 10 million, the consolidated energy saving rate up to 30 percent.
"The northern areas of existing buildings representing the local community of 25 per cent of energy consumption, energy saving space. "Jilin civil society building energy branch President Zhang wen said, energy saving, can effectively reduce the heating energy consumption, energy efficiency, reduce CO2 and pollutant emissions, to promote the development of low-carbon economy.
It is understood that the "eleventh five-year plan" period, the Department of State has issued to the North heating zone 1.5 million square meters of existing residential buildings heating and energy-saving transformation tasks and give a $ 55 per sqm bonus funds.
This policy greatly mobilized the provinces on existing buildings for energy saving. 2008 and 2009, the two year period, only the Jilin province to implement existing residential buildings heating and energy saving in 1647, 000 square meters, three-year mandate of two years to complete, and in excess of the national plan 547 million square meters.
"However, this number is still too small. "Jilin provincial Department of construction of housing and urban-rural construction energy conservation and Science Department Director Liu Lin said that countries in the North of existing buildings in terms of energy saving should be further increased.
It is understood that, at present, China has 40 billion square meters of buildings need energy saving, "eleventh five-year plan" period, the Ministry of construction only launched 1.5 billion square meters of task indicators, you cannot play an even greater demonstration effect.
Mr. Jenkins was of the view that China must complete 40%-45% of the emission reduction target, building energy saving should attract more attention, especially on "concept, whether from the point of view, or baominsheng emission angle on the existing building of energy saving should increase their efforts."
