The aim of the work was to determine the possibility of applying a solar system for heating, cooling and preparation of domestic hot water for a newly built residential building located in the city of Split. The computer dynamic simulation program for thermoenergetic and thermotechnical systems TRNSYS was used to perform the simulations. 3D model of the object was generated using the Google SketchUp program. In the first part of work, for the thermal mathematical model of the building, the annual energy consumption for heating and cooling was calculated depending on the type of shading. Then, for several technical systems for heating, cooling and preparation of domestic hot water, the selection of equipment and their implementation was carried out. Air-water heat pump systems, water-water heat pump systems and a solar thermal system with vacuum tube solar collectors in combination with an absorption cooling device were considered. In the system with heat pumps, a photovoltaic system is implemented for the production of electricity to cover the costs of operating the system. In the second part of the work, the energy and economic analysis of the system was carried out. Based on the analysis, the air-water heat pump system was selected in combination with the photovoltaic system, which proved to be the most cost-effective.
