Abstract:

Risk sharing structure in the existing reconstruction projects for building efficiency the characteristics of dissipative structure.The analysis of the risk sharing structure and the dissipative structure theory are applied for investigation of the formation mechanism of the risk sharing dissipative structure in the reconstruction project for building energy efficiency.On this basis，the direction discrimination model of risk sharing structure is constructed based on the grey relational entropy evolution model，and 3 kinds of evolution direction of risk sharing structure are presented.Lastly，suggestions for promoting collaborative governance，strengthening regulation，and designing contract are proposed.

Key words: building energy efficiency, risk sharing, dissipative structure, evolution direction
