An increased utilization of renewable energy sources in the heat and electricity generation is one of priority tasks of the Slovak Republic to boost the use of domestic energy potential and thus to decrease the Slovakia's dependence on imported fossil fuels. Heat pumps and photovoltaics offer the most energy-efficient way to provide heating and cooling in many applications, as they can use renewable heat sources in our surroundings. The experimental workplace of our Faculty "Economic Research Centre for Renewable Energy Sources and Distribution systems" was founded with the purpose of investigating possibilities to reduce the energetic costs of buildings tied to economy. The realized project of the Centre creates real environment for effective implementation research of technologies in laboratory and operative conditions: technologies of cogenerative elements, heat pumps, photovoltaics elements, thermal capillaries, and technologies in field of measurement and regulation. The article discusses the issue of prediction of electric energy production using photovoltaic system. The procedure and results of photovoltaic system simulation model are subjected to comparisons between measurement, simulation and calculation methods. In regard to results of the comparison is established simulation model of produced electricity for the buildings. Within indoor environmental engineering system is installed in a building as a source of cooling. In conclusion, energy balance evaluated the electricity consumption coverage of heating and cooling system using photovoltaic system.
