Domestic existing buildings is about 43 billion square meters

Indeed, building energy-saving development space. Dell Latitude D820 Accu Only from the insulation material, a point of view, taccounting for about 81% of all insulation materials, the laptop battery for less than 10%. Domestic existing buildings is about 43 billion square meters, more than 95 percent of high-energy buildings; annual growth rate of approximately 2 billion square meters, of which more than 80 percent of high energy consumers; 20% do energy-saving deal with 150 square meters of energy-saving investment The annual market increase of 60 billion yuan, which does not include the existing building energy-saving, domestic building insulation market is less than 2.5 billion yuan.

Around the building to use the theme of energy conservation, the main measures include the following three categories:A high level of thermal insulation of the building envelope. For example, Dell Latitude C400 Accu the window to take a multi-storey windows, insulating glass, Low-E glass, filled inert gas method, notebook battery so that the entire window heat transfer coefficient from 1.5 to 2.5W / (m2K) reduce to around 1.0W / (m2K); external walls insulation, especially the use of external thermal insulation, external wall heat transfer coefficient from 0.3 to 0.5W / (m2K) dropped to about 0.1 ~ 0.2W / (m2K); Dell Inspiron N5010 Accu building envelope insulation and good indoor heavy structure built with masonry.

(2) high efficiency heating, cooling, lighting and appliances, equipment and systems, reduce the heat transport, transmission and cold energy consumption, make full use of clean energy, and expand cogeneration or thermoelectric cooling by the laptop battery to expand the application of heat pump, energy storage, heat recovery and variable flow technology.(3) to maximize the efficient use of natural energy, First Solar. Other natural energy sources such as geothermal energy will also be utilized. Ground source heat pump can be used for building heating and cooling. The wind resource-rich places to make good use of wind energy. Of course, Dell Inspiron E1505 Accu building green is the common use of natural energy.
