This study presents a methodology that integrates Received in revised format multi-objective optimization and multi-criteria decision making MCDM in order to enable June 2 2019 construction decision-makers to select the most sustainable construction alternatives. Four Accepted June 30 2019 Available online objectives functions are investigated which are construction time lifecycle cost environmental June 30 2019 impact and primary energy in order to construct the Pareto front. A novel hybrid MCDM is Keywords designed based on seven multi-criteria decision making techniques to select the best solution Environmental pollution among the set of the Pareto optimal solutions. Sensitivity analysis is performed in order to Construction industry determine the most sensitive attribute and construction stages that influence environmental Multi-objective optimization emissions. The analysis illustrates that WSM COPRAS and TOPSIS provided the best rankings Multi-criteria decision making of the alternatives primary energy is the most sensitive attribute for different MCDM methods. Pareto front Moreover PROMETHEE II is the
