ABSTRACT
The paper presents and justifies the desirability of creating a zero-energy house focusing on renewable energy sources in the form of a heat pump and a photovoltaic installation. For the purposes of the study, actual results of a heat pump operation were obtained and compared with atmospheric conditions such as: temperature, humidity, and insolation. The size of the photovoltaic installation was selected, allowing the building to fully meet its energy needs. Furthermore, a program was created that allows people to select the appropriate pump power depending on the data provided by the investor or the selection company. On the basis of these data, the economic viability of the investment of this solution has been demonstrated.
