Study On The Energy-saving Reconstruction Management Of Existing Building

The stock of existing building in our country is large which consummate large amount of energy. So the reconstruction of the building that does not meet the energy-saving design standard becomes one of the most important and the most effective measures in the process of meeting the energy efficiency goals. This paper studies on the pre-management of existing building energy-saving reconstruction based on the project management principles and systematic methods. We propose the evaluation method of existing buildings energy-saving design and the analysis method of investment benefit. The paper designs the contract pricing mechanism of energy saving service and the mode of bank guarantees and loans. In the end, the paper studies on the management of a teaching building's energy-saving reconstructionFirstly, through literature review, inspecting the domestic energy-saving design standards and consulting experts, we propose the design requirements of existing building envelope and energy systems.Secondly, according to the energy-saving reconstruction of existing building, this paper analyses its major costs, and then gives the estimation methods and processes for investment in energy-saving reconstruction. The factors of building energy consumption and energy forecasting price have been analyzed to determine the earnings of building energy-saving reconstruction in the future. Finally, this paper describes the financial evaluation and investment risk analysis methods of energy-saving reconstruction benefits.Thirdly, through selecting principal-agent theory to analyze the building energy efficiency services, this paper points out that the current contract pricing process does not fully consider the asymmetric information, there is no rational pricing mechanism adopted to avoid the adverse selection and moral hazard. We find that the specific risk assessment can be analyzed by the dynamic risk-sharing model. The risk assessment is determined by the risk characteristics of different project and the contractors'risk aversion.Fourthly, through the way of questionnaire, this paper finds the main financing channel of energy service companies and analyses the main problems of the energy services companies'bank financing. Based on the analysis of the affect of mortgage and the guarantee for enterprises'financing by Yehning Chen model, this paper makes recommendations to the bank financing of the energy service companies and designs the financing mechanism of the building energy services company. The Government must provide credit guarantees by way of free or low-cost. This paper makes recommendations to the bank financing of the energy service companies and designs the financing mechanism of the building energy services company.
