Abstract: Abstract With the increasing number of aged buildings, the green retrofit of public buildings is effective way in urban renew process. In order to study the risks of existing public building green renovation projects, this study develops an improved FMEA (Failure mode and effect analysis) analysis model to quantitatively assess the risks. Experts in construction industry are invited to assess the risk factors of public buildings and green retrofit projects, and to determine the weights by entropy weighting method. In the improved FMEA model, the risk factors assessment results quantified by using the Likert five-level scale method, and the EWGM (exponential weighted geometric mean) method is selected to rank the RPN. Based on an empirical study in Chongqing, the top 5 risk factors of the public building green renovation projects of are obtained. Focusing on the assessment results, the possible potential causes of each high risk factor are analyzed, and corresponding risk response measures and suggestions are proposed. The research findings provide references for improving the risk management level of the green renovation project of public buildings.
