Using renewable energy is becoming more profitable nowadays because of applying advanced technology. The paper, presented by the authors, analyses the case of using solar and geothermal energy to create comfort in homes with low energy consumption. In this situation, the performance of the systems that take energy from low-heat renewable sources and convert it into useful energy is growing. The characteristics of the buildings with low power consumption, of passive houses in particular, can cause the development of a new generation of devices to create comfort. The energy used to create comfort in the first passive house built in Romania, which was designed for offices, analyzed by the authors, is using both geothermal and solar power. The authors present the energy performance of the building correlated with the performance of the air-conditioning system that uses ground-water heat pumps. The thermodynamic analysis presented, highlights how the performance of geothermal energy systems increased, their variation depending on the climate zone variation parameter values. The authors make a detailed analysis, in the presented paper, about the influence of the working conditions of the installation elements, on the heat pump energy consumption and the methods adopted to reduce losses and increase system performance.
