Research On Incentive Mechanism Of Ultra-low Energy Consumption Building

In recent years,China’s social energy consumption situation is severe,and the building energy consumption has accounted for nearly one third of the total social energy consumption.Under the realistic situation that building energy consumption is increasing year by year,it is urgent to start promoting ultra-low energy consumption buildings that can effectively reduce building energy consumption from the perspective of economic development and international responsibility.Due to the late start of ultra-low energy consumption buildings in China and uneven development areas,they are still in the stage of technology demonstration and promotion,and their economic externalities make the importance of government incentives self-evident.Based on low energy consumption building,the present situation and problems of development and policy on the basis of considering the lifecycle of the building,analysis of the incentives of the government needs to take and developers to build low cost benefit of building energy consumption,build a game model between government and developers,stable equilibrium calculation,puts forward Suggestions for the government’s incentive intensity.Finally,combining with the evolutionary game simulation method of the incentive mechanism model,this paper makes an empirical analysis on the prospect of the promotion of ultra-low-energy buildings in hubei province,and puts forward some Suggestions on the incentive policies for the development of ultra-low-energy buildings in hubei province.The results show that the government of hubei province should subsidize the incremental cost of building developers with a certain proportion of ultra-low energy consumption buildings.In addition,it can also increase the plot ratio incentive and the price subsidy of commercial housing.Secondly,in order to maintain the continuous operation of ultra-low-energy buildings,it is suggested that the developer bear a certain proportion of the maintenance and replacement cost in the life cycle cost of ultra-low-energy buildings.The government can also reduce the cost of building ultra-low-energy buildings by strengthening research and development of related products and technologies and promoting industrial chain development.Finally,the government should improve the system of policies and regulations on ultra-low-energy buildings,strengthen the supervision system,expand the scope of pilot projects and strengthen the promotion,so as to promote the development of ultralow-energy buildings in hubei province.
