Abstract:
This paper addresses the issue of energy efficiency in housing and the reduction of solid fuel consumption and energy consumption. It simulated the cost and efficiency of a photovoltaic system and a hybrid system consisting of an air-water heat pump supported by a photovoltaic system. In the first part, the solid fuel requirements for heating the house were calculated taking into account the materials used in the construction of the house and the insulation. At the same time, data on the location of the dwelling and the area in which it was built were also used. It was noted from the calculation that CO2 emissions are high over a year. Thus the use of green energy was chosen. Furthermore, the energy efficiency of the house was studied by using a photovoltaic system. In order to optimise the hW requirements of the photovoltaic system the software Homer Pro was used. With the help of it we obtained data on the cost per kW for several PV system variants. Calculations were made for the cost of a hybrid air-water heat pump system supported by a PV system. This system brings the house closer to a green house. In conclusion, even if the initial cost is high, the advantages of using green energy are many. In addition, the investment pays for itself over time.
