With China's rapid economic development , building energy consumption is growing rapidly, the energy crisis and the consequent environmental issues is the most important issue facing our country . Quite a large number of our existing buildings built in the 1980s and nineties, the simple design of the building envelope , windows and doors gap , building insulation, air tightness , poor residential thermal environment , building energy efficiency low, low level of building energy efficiency , the rare energy saving measures . Therefore, the ability of the existing residential building energy transformation , determine whether the promotion of resources , the efficient use of energy , and take the road of sustainable development . The work of building energy efficiency in China is advanced to the south from the north , is located in Changchun City, Jilin Province, northeast belongs to cold regions , Changchun City, Existing Building Energy Saving work is an important part of the work of building energy efficiency in China , winter heating energy consumption accounted for building energy consumption of up to 50 % to 60 % energy saving potential is huge , as the residents of the improvement of the indoor thermal environment requirements and related energy saving policies and regulations , the transformation of the existing residential building energy research will have practical significance . In this paper, the survey of existing residential building energy transformation in Changchun City , mastered both residential energy saving awareness and support of existing residential building energy situation and the people in Changchun City , Changchun City in need of rehabilitation typical residential model , as Research existing building energy-saving program to provide a reliable basis . Calculated using theoretical analysis based on simulation of computer software , and Changchun City Existing Residential Building Energy Saving best solution on mathematical and statistical analysis of the three methods , and the economic and environmental effects analysis program . The actual reference value for further development of Jilin Province, Existing Building Energy Saving work .
