Hotel buildings, with high energy consumption and complex systems, are prime candidates for carbon-reducing retrofits. From the Energy Service Company (ESCO) perspective, this study assesses risks in Energy Manage-ment Contracting (EMC) projects. Using the Work Breakdown Structure (WBS) method and Delphi Method to identify risk factors, and constructs the improved entropy weighting method-DEMATEL-ISM risk assessment model. The Fuzzy Comprehensive Evaluation method determines the project’s overall risk level. A case study of an EMC renovation in hotel X revealed that key risks include financial management risk, energy-saving technology risk, financing capability risk, talent risk, and project decision-making risk as critical factors demanding focused prevention and control. The project was assessed as close to low risk, providing insights for similar building energy renovation projects.

摘要

Hotel buildings, with high energy consumption and complex systems, are prime candidates for carbon-reducing retrofits. From the Energy Service Company (ESCO) perspective, this study assesses risks in Energy Manage-ment Contracting (EMC) projects. Using the Work Breakdown Structure (WBS) method and Delphi Method to identify risk factors, and constructs the improved entropy weighting method-DEMATEL-ISM risk assessment model. The Fuzzy Comprehensive Evaluation method determines the project’s overall risk level. A case study of an EMC renovation in hotel X revealed that key risks include financial management risk, energy-saving technology risk, financing capability risk, talent risk, and project decision-making risk as critical factors demanding focused prevention and control. The project was assessed as close to low risk, providing insights for similar building energy renovation projects.
