Study On Profits Allocation Of Energy Performance Contracting For Sustainable Building Energy Efficiency Retrofit Of Existing Residential Buildings In Heating Regions Of China

In our country,existing residential buildings energy efficiency retrofit is mainly based on the government leading model in the previous time. But the limitation of government’ funds has limited the development of existing residential buildings energy efficiency retrofit. Energy Performance Contracting is a kind of market-oriented energy efficiency innovation operation mode,which can achieve the integration of resources of existing residential buildings energy efficiency retrofit. However,facing various ways of heating mode and retrofit mode,the profits allocation of Energy Performance Contracting for sustainable buildings energy efficiency retrofit of existing residential buildings still has some problems that the subjects and objects under different technical and economic conditions of profits allocation are analyzed vague.The paper is based on the logic route of “profits allocation subjects→profits source→means of profits allocation→model of profits allocation→model solution”to carry out the research:According to different concentration degree of residential buildings’ heating,heating modes are divided into centralized heating mode,semi centralized heating mode,relative centralized heating mode and decentralized heating mod,using stakeholder theory,focusing on Energy Performance Contracting project,the profits allocation subjects under different heating conditions and different categories of retrofit are overall analyzed. The profits of sustainable buildings energy efficiency retrofit of existing residential buildings is analyzed from three aspects,which are heating profits,refrigeration profits and external profits and the calculation formulas of them are given respectively. Energy Performance Contracting is reclassified based on different investment modes of Energy Performance Contracting projects,the characteristics,applicability and the corresponding profits allocation modes are analyzed among the types of energy service corporation contributing projects,residents contributing projects and mixed subjects contributing projects. For settlement of expense payment belongs to one time transaction,which isn’t involved in further profits allocation,so the profits allocation model of profits sharing and fix price plus incentive fee are established with cooperative game theory,subsequently the models are resolved by Shapley value method which has amended by risk compensation. Finally the follow-up work is looked forward.
