Northern Jiangsu Civil Energy Applications

China is a large population and relative per capita resource poor country. As a result of rapid economic development, the rapid growth of energy consumption, Energy,land and other resources have become increasingly prominent, and have become china's major constraints of sustainable economic and social development . According to the survey, community building energy consumption accounts for 28% of total energy consumption, With the "People's Republic of China Energy Conservation Law" caming into effect, on April 1, 2008, it is realistic and far-reaching significance to implementa energy conservation for buildings to save energy, protect of land resources.The paper try hard to Jiangsu Northern Area building energy-saving innovations, and establishs regional climate characteristics Jiangsu Northern Area natural conditions of the civil construction and energy-saving systems, which can not only ensure the building of energy-saving, effect of comfort, and help conserve resources, lower costs, but also energy-efficient construction is the key to retaining the structure of the external binding properties of thermal insulation .In general civil construction, energy consumption on heating, the wall heat consumption accounting for 35% -45%, window for 23% -25%, doors and balcony doors households account for about 5%, the roof about of 8%, air infiltration accounts for 18% -22%, bottom only the 2%. Therefore, this paper research on thermal power accounted for 80% of the external walls, windows, doors and level, discussed the 4 types of commonly used wall, 3 types of doors and windows, 5 of the thermal performance of roof , energy-saving design of energy-saving building materials have played a role in promoting good. The paper in accordance with the purpose of the overall framework of meaning - The natural conditions in North Jiangsu areas - planning and design - performance analysis of retaining structure - thermal analysis of buildings -practical engineering applications and summing up the logic of the order of arrangement.The specific content of the article is: The first chapter introduces the research background and purpose of the significance of introduced foreign civil construction of the development and application of energy-saving situation, as well as the idea of this paper, structure and content. The second chapter introduces the impact of building a major factor in energy consumption, as well as the constraints of the characteristics of Jiangsu Northern Area. The third chapter introduces Jiangsu Northern Area planning and design of energy-saving buildings. The fourth chapter introduces the main areas of common envelope Jiangsu Northern Area structure and classification of energy-saving insulation measures to the characteristics of thermal insulation system. The fifth chapter focuses on the status of building thermal analysis methods and thermal analysis, as well as energy-saving measures in the specific characteristics of engineering. Finally, summing up the whole article come to the conclusion and analysis of existing problems and propose directions for future research.
