To Building energy efficiency Concern, whether in the office Jinde Jun Director General Ministry of Construction Project Division, construction and management Secretary during the period or in the work of the CST have been relaxed. But the real concern for Jin Zhuren Ground Source Heat Pump Technology, or was he took over after the work of the CST.
Jinde Jun director, said in early 2005, I went to work of the CST. Contact with the first issue is the building Energy Reduction. I am concerned about the ground source Heat Pump This is from the construction point of view of energy saving. I know, building energy reduction targets despite clear, but the task is very heavy, and we are in a period of rapid development of urbanization. Volume of housing construction is growing every year, statistics show that the completion of each volume are more than 2 billion square meters. I think this growth will continue for a period of time.
Building energy end energy consumption in the whole society which has accounted for about 27.5%, and this does not include the construction process using the materials consumed Energy Mainly refers to steel and cement. According to the information that the terminal building materials energy consumption to energy consumption accounts for 16% of the community. So doing, building energy consumption reached 43.5% of the. With the increase in the volume and the increase in urban population, our per capita use of energy demand but also to improve, and that the per capita energy use showed a lot of coal. Overall, the building will increase the proportion of coal.
Faced with this situation, how energy-saving building construction to reduce emissions all have very important meaning. Of course, the realization of the path of building energy saving, there are many, but I understand that the use of ground source heat pump technology development and utilization of shallow geothermal energy is a practical way. Because it is the biggest feature is the use of relatively small amounts of high-grade energy, to develop this low-grade underground reserves of energy used by buildings. Obviously, this is good for energy conservation. In addition, it saves the conventional energy, it must achieve emission reductions. When the shallow geothermal energy combined with the air after its advantage even more pronounced. We are using air conditioning is to heat emission in the air, the city would naturally increase the temperature, and the formation of a huge heat island. Now reduced precipitation in major cities, and urban heat island effect I see is a relationship focused. If the shallow geothermal energy after the heat discharged into the ground, and thus reduce the use of conventional energy realized when the thermal pollution of air, in particular, the thermal pollution of the city. Therefore, the use of ground source heat pump technology development of shallow geothermal energy is a good way, not only energy saving, no pollution, and sustainable. From the energy quality, character point of view, this low-grade shallow geothermal energy use in the construction of the heating and cooling and domestic hot water, the very counterpart.
Speaking of which, Jinde Jun director cheerfully asked us: Do you think that not so? Because the building does not require high-grade energy. The land-source heat pump technology to shallow geothermal energy development out of this low-grade applied to architecture, it seems to be prepared specifically for this industry like. Applicability of its industry, industry has the advantage of the shallow geothermal energy project and the construction industry closely linked. Therefore, it is one of the reasons to attract my attention.
