The building energy demand simulation tools consist the compass of the roadmap towards the energy efficient building. Apart from the software itself, the result of the simulation strongly depends on the degree the data used represent the actual situation, among which the climate data of the area are a key factor. In this work, the energy demand of a large building complex is estimated, using the widely accepted EnergyPlus building simulation software in combination with two, also widely accepted, weather files. The simulation results for heating are compared with the actual fuel consumption of a three-year operation period. The comparison reveals that the weather file and the size of the simulation domain significantly affect the simulation representativeness.
