Identification and Prioritization the Risks of Green Building Projects Based on the combination of FANP and FDEMATEL: (Case study: Savadkooh County)

Green buildings are consistant objects which consider environment issues and natural resources throughout the life cycle. The risk of a green construction project reduces the accuracy of the estimation of the projects objectives and reduces the efficiency of green building projects. Therefore, identification and prioritization of risks can play a significant role in the success of green construction projects. In this research, we present a comprehensive model of all criteria and indicators of the risks of green construction projects; we have made the final ranking of green building construction risk indicators so that we can reduce the risk of green projects at run-time. For this purpose , at the first step, the identification and screening of indicators from the viewpoint of experts in green construction projects is considered by using the Fuzzy Delphi technique and then, the new method is used to combine the results of the network analysis process and the DEMATEL technique in fuzzy conditions to rank and evaluate the causal relationships between the factors and ultimately final prioritizing green building risk indicators have been done in terms of the results of the initial steps using the fuzzy Analysis Network Process (FANP) and DEMATEL technoique. The results of the research show that the risks associated with poor quality of materials and inappropriate equipment are very important and the lack of scale for the cost of activities has the least importance.
