Abstract: The effectiveness of implementing energy-saving renovation projects in existing buildings under EPC mode depends on the value and effectiveness of investment management. The value implementation path of implementing energy-saving renovation projects in existing buildings fundamentally lies in investment risk management based on comprehensive evaluation of benefits and reasonable distribution of benefits. Starting from the core content of ESCO investment management in existing building energy-saving renovation projects, a special study was conducted on "Comprehensive Benefit Evaluation of Existing Building Energy Efficiency Renovation Projects Based on Value Added Life, Optimization Mechanism of Income Distribution of Existing Building Energy Efficiency Renovation Projects under EPC Mode, and Investment Risk Analysis and Control Strategy Research of ESCO Existing Building Energy Efficiency Renovation Projects". The research ideas and logic of investment management were constructed from three basic levels, and the overall framework was constructed A hierarchical system consisting of five modules and three chapters, including comprehensive benefit evaluation of existing building energy-saving renovation based on value-added life, optimization mechanism of income distribution for existing building energy-saving renovation projects, investment risk management and summary for ESCO existing building energy-saving renovation projects. Establish a value implementation path for ESCO investment management in existing building energy-saving renovation projects: a theoretical system of benefit evaluation, income distribution, and risk management, providing theoretical support and practical reference for ESCO investment management in existing building energy-saving renovation projects, and using the value of ESCO investment income to promote the progress of existing building energy-saving renovation projects and the healthy development of the market.
