Fourth, China's building energy efficiency goals

The first phase of the target: from now until 2010 to start building a comprehensive energy conservation and promotion of green building, with an average energy saving rate of 50%. Means that not every building energy-saving rate will reach 50%, but because the green buildings more energy-saving rate may be higher, along with a considerable number of old buildings may also be too late to carry out energy-saving, so the average to achieve 50% of the saving rate. The coastal provinces and cities will have to meet higher standards.

The second phase of the target: from 2010 and 2020 to further enhance the building energy efficiency standards, with an average energy saving rate to reach 65%, the eastern region to achieve higher standards. This means that in the next 15 years, a number of building energy-saving rate should reach 75% standard. This requires us to seize the opportunity to again when the renovation or re-transformation, building energy-saving rate should reach 65% or higher standard.

If we can achieve these objectives, in 2020, China's building energy consumption can be reduced 335 million tons of standard coal, which is equivalent to 2002 the total amount of energy consumption throughout the UK, this is a very impressive figure, the sustainable development of human society is also a huge contribution.

For the building energy efficiency, we have two choices: First, if we do not seriously take the time to promote building energy efficiency, the building energy-saving policies and standards are not implemented, the final result is that building energy consumption continued to rise, coupled with the rapid urbanization, population increase, to 2020, China's building energy consumption will be nearly 1.1 billion tons of standard coal, which is a huge number. Second, if we can achieve two milestones in 2020, China's building energy consumption will be reduced to 754 million tons of standard coal, saving 350 million tons of coal. In this way, we can reduce air conditioning peak load of 80 million kw / h, equivalent to 4.5 Three Gorges power station at full load generating capacity. If in 2020 China's building energy consumption can reach the level of developed countries in the late 20th century, energy-saving effect will be more prominent. Therefore, we invest heavily in building power stations in the facilities to alleviate the situation of China's current power shortage, we must take full account of the great potential of building energy efficiency. If you do not change the current status of the construction of high energy consumption, even if the Three Gorges Project to build 10 power plants can not meet our demand for electricity.

Fifth, Green building development in the four major strategies

1 To enforce energy efficiency standards. Establish a sound regulatory system for building energy efficiency, improve building energy efficiency standards, the development, including architectural design, construction, inspection, testing, running the strict standards and regulations. All new buildings need to enforce energy efficiency design standards. The central government department in charge of experts regularly check the local building energy-saving implementation of the plans and progress. For the non-implementation of standards in all relevant units, according to the responsibility to give a fine, exposure, restricting access to markets, qualified or qualified to carry out the disposal of a variety of
