Abstract: Modeling of energy systems in the building sector is one of the most fundamental topics in energy systems engineering. Multi-criteria decision-making methods have also had many applications in this field. This paper models an energy system regarding combined cooling, heating and power (CCHP). In his regard, for a commercial building, the energy system was modeled in six different scenarios. Then, using multi-criteria decision-making methods and considering economic, technical and environmental indicators, scenarios were analyzed and ranked. To obtain the criteria weights, the CRITIC and Shannon's Entropy methods were used, and by introducing a novel weight integration method, the weights were combined to obtain the final weights. Finally, the scenarios were ranked using the EDAS method. The results revealed by changing from scenario S1 to S6, economic indicators decrease and the values of net present cost, levelized cost of electricity and operating cost lower by 38.64%, 36.14% and 40%, respectively. It is also shown that the combination of solar system, grid, boiler and electric chiller as well as solar system, grid, boiler, gas generator and absorption chiller were the most favorable energy systems for the building.
