Economic analysis of the residential buildings in cold area implementing different energy saving standard

In this paper, the software of DeST-h was used to simulate the heating energy consumption of a typical energy-saving residential building by the year in cold area. The paper researched the implementation of the 50% of the energy-saving standards and the implementation of the 65% of the energy-saving standards in different circumstances, the cold area of residential building heating energy consumption change,investment and operation cost, energy saving and emission reduction.
