Current, our country is facing very grim situation of energy, energy consumption is very large, especially in the building energy consumption is above 30% of total energy consumption, building heating energy consumption of unit area is the international climate similar to the developed countries from 2 to3 times, make the building energy efficiency has become a focus of energy saving in our country. In addition, China's urbanization is in the high speed period, GDP of our country average per capita has close to 2000 U.S. dollars, it is dweller consumption structure upgrades into the stage, and living conditions continue to improve, to building thermal comfort requirements are increasingly high, heating and air conditioning is used more and more widely, the per capita energy consumption will increase rapidly. Therefore, construction of new energy-saving technology be imperative.
" Eleven five" period the main building energy conservation work, a new architecture is the full implementation of energy-saving 50% of the design standards, the establishment of four municipalities directly under the central government and the northern area to achieve 65% national standard technical support system, completed in 100green building and the super low energy architecture demonstration; two is the existing building reformation, especially public buildings should be made breakthrough progress, require large city to complete the transformation of area 25%, medium city is finished 15%, small city finished 10%. At the same time North heating system reform is finished basically, drive north of existing residential building energy-saving; three is the construction of renewable energy in the size of the application of essential breakthrough; four is formed by state and government at all levels to promote the construction of energy-saving regulations mandatory impetus.
The Ministry of construction required the implementation of energy-efficient building standards is a result now, benefit is in a thousand years decision, according to the planning of building energy saving in our country, to 2010 countrywide new building for more than 1/3to achieve energy conservation and green building construction standard, the urban construction of the total energy consumption to achieve energy saving of 50%, to 2020to further promote green building and energy saving construction, realize the majority of existing buildings for energy saving, so that the whole society building total energy consumption to reach the goal of 65% energy saving.
The country publishs4trillion yuan economic stimulus plan, the construction industry is the major field. With the development of the construction industry to increase investment ceaselessly, building energy conservation plan will get promotion. Polyurethane as the world's best insulation material, has been widely used in building external wall thermal insulation system of exterior wall thermal insulation, in the future, there will be greater development of polyurethane.
