| Now, the issue of energy has become the focus of attention of the world, humans in order to meet the growing demands for the energy, and the Earth’s non-renewable resources dwindling, gradually increasing both contradictions, humans will face energy shortages. With the rapid development of China’s economy, the demand of energy is increasing, Energy conservation strategy for sustainable is our strategy in China,we have to establish the saving society. The energy consumption of building account for a large proportion of the energy consumption, the energy consumption of building has more than one-fourth of total energy consumption nationwide, and has continued to increase, so saving energy of building has huge potential.The energy efficiency of Building has become the important subject of the research topics, Western developed countries have accumulated extensive experience in building energy-saving, meanwhile some advanced technology be used, but our contury’s building energy-saving technology is still developing, there is still a large gap with Western countries, have a broad space for development. Residential buildings occupy a large proportion in China type, high energy consumption. In cold aera,energy-efficient design is particularly important, because of long heating time and heating characteristics of high, design standard for energy efficiency of residential buildings in cold area is currently saving energy consumption enhance65percent than1981’standards by improving building energy efficiency, while improving internal comfort of residential buildings, reducing energy consumption, achieve the sustainable development of constructionThis paper select Shenyang city for cases, based on local energy-saving design specification, combined cold area of geographic climate features, for city heating live building energy-saving design for research, clear energy-saving design standard of upgrade range, from building planning layout, and monomer design starting, made applies the area of design policy and the rationalization proposals; focus on building of outside insulation wall body, and doors and Windows, and roof, and building ground, retaining structure of energy-saving constructed design in the exists of problem, Discuss the important parts and building practices and a optimal design; At the same time a new point of view of energy, listed in residential construction can be widely promoted in the coldest zone of technical measures; And describe the have a large impact on building energy-saving and other energy-saving technologies with existing energy efficiency standards that are appropriate.Liaoning province Publish local standards of the design 《Design standard for energy efficiency of residential buildings》(DB21/T1476-2006), in2006and2011, and 《Design standard for energy efficiency of residential buildings》(DB21/T1476-2011)(version06is the same as the version11), two editions of standards is also aimed at energy saving rate of65%developed. The version11compared to the standard version06, thermal design provides for certain improvements. This case study of a typical high-rise residential, respectively, according to the Shenyang local06Edition and standard version11, design different building envelope insulation construction programme of energy-saving standards, through comparative analysis, verify that the application of energy saving technology of optimization effects. After the standard level of countermeasures and suggestions to explore the energy-saving design of heating residential buildings in severe cold region towns in China improve the technical route.This article Submit building energy-saving design and direction of development in cold area, through research on the residential energy-saving in cold aera, provide the theoretical foundation and technical support. |
