Analysis on Evolutionary Game of Participating Subjects in Existing Building Energy Efficiency

Now the largest improvement for building energy efficiency were achieved in new building and the existing buildings are still 75% belong to the high-energy buildings in China. Building energy efficiency working mainly depends on the implementation of the mandatory building energy efficiency design standards and neglects the role of economic incentives. Building energy efficiency mainly has the government and the owners of two related participants who will continue to game select to protect their own interests' maximization. This paper concludes with a discussion of evolution game of market mechanism and government regulation: In initial implementation stage of existing building energy efficiency strategy, the government should provide certain concessions to the energy efficiency owners and give the not implementation energy efficiency owners some punishment. However moderate punishment should be chosen. Because under certain conditions, the greater the punishment more conducive to promoting the owners to implement energy efficiency, but the punishment is too large, it will play a negative role.
