基于合同能源管理模式的既有建筑节能改造项目经济效益评价方法研究

Economic Benefit Evaluation Method of Existing Building Energy Conservation Reconstruction Project Based on Contract Energy Management Mode

基于合同能源管理模式,为降低项目投资风险性,需在实施前进行科学合理的经济性评价。但对于既有建筑节能改造项目而言,其涉及的功能领域广、技术类型多,且各类技术特点及运营模式均各有不同,若针对各项目特点分别选取不同的经济效益评价指标并逐一对其进行评价,将会极大降低项目经济效益评价工作的效率。因此,将基于工程经济学理论及工程实践经验,选取具有通用性特点的经济效益评价指标,并为采用合同能源管理模式的既有建筑节能改造项目提供科学合理、可操作性强的经济性评价方法,旨在提高改造类项目经济效益评价效率,有效降低项目投资风险。

In order to reduce the investment risk of contract energy management project,it is necessary to conduct scientific and reasonable economic evaluation before the implementation of the project.However,for the existing building energy-saving reconstruction project,it involves a wide range of functional fields,many technical types,and various technical characteristics and operation modes are different.If different economic benefit evaluation indicators are selected and evaluated one by one according to the characteristics of each project,the efficiency of the project economic benefit evaluation will be greatly reduced.Therefore,based on the theory of engineering economics and engineering practical experience,this paper will select the economic benefit evaluation indexes with universal characteristics,and provide a scientific,reasonable and operable economic evaluation method for the existing building energy-saving reconstruction projects adopting the contract energy management mode,in order to improve the economic benefit evaluation efficiency of reconstruction projects and effectively reduce the investment risk of projects.
