At present, China is still using coal as the main fuel, urban energy structure is irrational, quality energy such as natural gas and solar, geothermal, wind and other clean and renewable energy in the building is still very low utilization. At present China's new housing construction in urban and rural areas each year more than 85% for high-energy buildings, existing buildings more than 95% is a high-energy buildings. China's unit energy consumption of building area two to three times in the developed countries, on the community a heavy energy burden and serious environmental pollution, which has become a constraint to sustainable development of China's outstanding problems. At the same time building utilization of land resources are still low, water pollution, construction supplies advanced problems.

4 Pairs of high prices and high cost of misleading

In the real estate sales to advertising hype bombing and the prevalence of the concept of the era of "green building" has become a real estate business, without exception, are easy to sing a new word, so let people mistakenly believe that green building is a high-end construction. The green building and building energy-efficient development path positioned on high-end, aristocratic, will not be successful; Facts have proved that the path of development identified as Chinese-style, ordinary people type, applicable technology type, green buildings will develop healthily.

5, Limited to new construction

According to Ministry statistics, the new buildings in the design phase of the implementation of the implementation of mandatory energy efficiency standard rate of 53% from 2005 to 2007 increased 97%; the construction phase of the implementation of the implementation of mandatory energy efficiency standard rate of 21% from 2005 to the 2007, 71% of the total annual savings of about 7 million tons of standard coal. Within the next 30 years, we have more than 400 billion square meters of new construction, under the existing construction management system, reach the green building standards are not allowed to start, so only a new implementation of energy-efficient buildings, the difficulty is not very . Difficulty is that China is now the existing 40 billion square meters of energy-saving buildings,how to make existing buildings into green buildings.

6, Building energy conservation is not only government's duty

Building energy efficiency and green buildings, can not just stop at experts, government officials and some large enterprises, large cities, should enter the homes of ordinary people. To let people know what is green building, not with flowers grass, fountain pool, green well in real estate is the "green buildings." If the ordinary people can be concerned about building energy-saving and green buildings, have taken note of the energy consumption of housing, materials, indoor environmental impact of carbon dioxide gas emissions, then we will form the consensus of market demand for green building. With the market demand, building energy efficiency and green buildings in order to promote a society-wide application.

The lack of awareness and knowledge of green building

The imperfect standard specification system

The irrational urban energy structure

The misleading of high prices and high cost of

The limit of new construction
