Abstract:
Green construction projects are initiated in complex and dynamic environments resulting in
circumstances of high uncertainty and risk, which are compounded by demanding cost and time
constraints. This paper describes a systematic way to consider and quantify uncertainty in green
construction process based on LEED rating system adopted by Indian Green Building Council (IGBC).
The system incorporates knowledge and experience acquired from many experts, project-specific
information, decision analysis techniques, and a simulation model to predict risks for different green
ratings in the construction schedule at the initiation of a project. The model provides sensitivity
analyses for different outcomes wherein the effect of critical and significant risk factors can be
evaluated. The study focuses on lessons learned from past projects and describes a risk assessment
process involving typical inputs and expected outputs. The paper also investigates practical
applications of risk management in green construction industry.
