مدل های میزبانی هزینه های انرژی: بهترین مدل کسب و کار در مرحله توسعه قرارداد انرژی عملکرد

Energy Performance Contracting (EPC) is a significant business mechanism to reduce energy consumption of existing buildings. At present, there are three basic business models of EPC: Guaranteed-Savings Model, Shared-Savings Model and Energy Costs Hosting Model. We suppose that the Energy Costs Hosting Model, in which building owners, Energy Service Companies (ESCOs) and financial institutions can achieve optimal benefits, is the most suitable business model in the developing stage of EPC. We construct benefits distribution models which involve three stakeholders based on interval-valued fuzzy Shapley value, adjust these values according to the actual allocation of energy-saving benefits and compare the benefits of the three stakeholders in the three business models. We conclude that Energy Costs Hosting Model can bring the maximum benefits to these three stakeholders and the participation of governments and authoritative institutions of authentication and appraisal can solve two major problems: ‘unshared information’ and ‘lack of supervision system’.
