合同能源管理模式下被改造居住建筑剩余使用寿命研究

EMC model has been successfully applied to the field of industrial energy saving and public buildings energy saving since it was introduced into China. However, for our country in the new urbanization process，urban construction and demolition of residential buildings are frequent, it is difficult to determine the remaining service life of the existing residential buildings, which influence the decision of pay back period of the residential buildings energy saving reconstruction under the EMC model, so the development of EMC model in the field of existing residential buildings is slow. So establishing Weibull distribution life-span calculation model to estimate the average actual life of residential buildings in specific area, and then get the remaining service life of residential buildings.
