Abstract: A multi-criteria optimization methodology is applied to an energy system composed of an earth-air exchanger and a heat pump. The aim is to determine the best sizing for different European capitals climates. The procedure is composed of a sensitivity analysis which determines the influential parameters using the FAST method. Then, a multi-criteria optimization is conducted with NSGA-II genetic algorithms to identify the Pareto front. Finally, a decision-making is performed to select the best compromise with the TOPSIS method. The results show that even if the system is dependent on weather conditions, it is still profitable, autonomous and efficient.
