Abstract:The preference of public building owners to the energy saving incentive Instruments of building determines the influence of policy tools,which is formulated and implemented by the government.In this paper,firstly we defines the types of building energy-saving incentive policies,and identify the influence factors of public building owners to incentive policy tools.Secondly, we analyzes the characteristics of the factors affecting the policy preferences of the public buildings, the preference of the public building owners to those policy tools and the relationship between them.Finally, in order to improve the energy efficiency of public buildings,the paper puts forward some policy suggestions for the government.
1.IntroductionIn recent years, with the rapid economic development, China's total energy consumption is growing rapidly year by year. China's building energy consumption accounts for 33% of the total social energy consumption, and the average per unit area energy consumption of public buildings is two or three times as much as other buildings [1] . Therefore, it is the fundamental way to realize the goal of saving energy by transforming the energy saving potential into the internal driving force of energy saving behavior under the guidance of the policy.Compared with other buildings, public buildings have more demonstration effect and social influence. Therefore, it is imperative to solve the high energy consumption of public buildings. The research results show that the incentive mechanism is an effective way to solve this problem. According to the different functions, this paper divides the public buildings into four types: government office buildings, medical buildings, shopping malls, hotel buildings. The existing incentive policy is not significant [2] .Shuai Gao finds that the owners' preferences for a variety of domestic policies determine the success of energy efficiency incentives or not. However,most research on the incentive policy tools of public buildings is based on the theoretical level, so they don't provide enough support in practice. Therefore,this paper pay attention to the preference of public building owners to incentive policy instruments from the perspective of the practice, basing on the motivation to stimulate the enthusiasm of the owners.
Literature review and model building
2.1.Types of building energy-saving policy toolsThe incentive policy tools have different effects on the target groups, so different types of public building owners may have different preferences for the same incentive policy tools [ 3] . Many domestic and foreign scholars have carried out a study on the energy saving incentive policies. In this paper, the author sorts out the classification of building energy efficiency incentive policies, as shown in table 1.
