Due to the increase in energy consumption in the world due to the increase in its demand in various sectors, the need to reduce energy consumption and provide solutions related to this field has become evident. In the past, many efforts have been made to reduce energy consumption in the building operation phase. But currently, attention is being paid to the optimization of energy consumption in the construction phase. One of the problems in optimizing energy consumption in the construction phase is the complexity of calculations and the unwillingness of contractors. The reason for contractors' reluctance to use energy optimization systems in the construction phase is not considering the cost and time of the project in these systems. The main goal of this research is to provide a system to optimize the energy consumption, cost and time of the project at the same time. In this regard, first, information is collected from building information modeling through IFC. Then, the processes in the construction phase have been simulated using discrete event simulation software. In the next step, using optimization algorithms, the various available options have been examined and then they will be compared with the financial and time constraints to extract a group of acceptable solutions from the perspective of energy, time and cost. Finally, by using decision making methods between acceptable options, the optimal option has been selected. To eva‎luate the performance of the presented system, this system was implemented on an industrial project located in Khorramshahr city. The results obtained from this implementation show that the presented system has good power, speed and accuracy in implementing optimization processes and finding the optimal option for construction. Also, the results show that there is a significant potential in reducing the time and cost of the project, which in the case study has the ability to reduce the cost by 7%, energy by 7%, and time by 29%. The reason for the decrease in energy consumption during the construction phase is that most of the energy consumed in this phase is related to the consumption of materials, which can be seen by changing the materials in the construction phase.
