Submitted work studies feasibility of construction of a 3 storey residential and office building in the passive house standard in climate conditions of Stará L'ubova, North-Eastern Slovakia and the analyses the sufficiency of renewable energy sources to supply the energy demand for heating, domestic hot water preparation and lighting. The work included search for suitable location for the building, designing the dimensions and setting the energy-related parameters of its construction materials and components. Than a calculation of energy balance of the building has been done to analyse the possibility to reach passive house standards. Calculations shown that it is feasible to construct the building of the design in the passive house standard although higher quality construction materials and components than minimum required must be used. Energy demand for heating can be fully supplied by air recovery and heat pump. Energy demand of the building can be fully covered from solar thermal system. Installing photovoltaic modules would suffice to cover electricity demand for lighting.
