Application And Research On Building Outer Wall Heat Preservation Technology

In the developed countries, building energy conservation is the main content of carrying out national environmental protection and implementing the national economy sustainable development.But our country at present construction conservation is much lower than the developed country, Our country's construction unit area energy consumption is 3 to 5 times than the developed countries which climate is close to our country. The building heating energy consumption occupies more than 20% of the local entire society energy consumption in the northen cold area, most of these use the thermoelectricity generation and the coal-burning boiler, bringing the serious pollution to the environment. Therefore construction energy conservation is the important topic to our country's building industry in the 21th century.In the construction, heating loss in the outer structure is great , most of loss lie in the wall itself, therefore the construction wall reform and the wall energy conservation technology developmentis the most important link in the energy conservation technology, the wall heat preservation technology and the energy conservation material is the main realization way to realiza.On the basis of summarying experience with the author working unit– Northeast Normal University. applying to use many kinds of outer walls technology. The text analyses outer wall heat preservation, through analysising and research for several outer wall heat preservation technologies in the Changchun area. The text carries out the preliminary discussion on the issues of outer wall heat preservation technology material constitution, constructional technologies, actual effect etc-which draw the following several...
