摘要
The object of this research work is the comparison of the annual primary energy consumption of different types of heating systems, using two different calculation methods. The TRNSYS 18 software makes use of dynamic simulation, while the Win Watt software calculates according to the Hungarian implementation of EPBD (Decree No. 7/2006). There were differences in results which could be caused by the more precise calculation of the TRNSYS software. Differences were shown also in the weather data used by the two computer tools that had one of the most important effects on the results according this investigation. The number of heating degree days used by TRNSYS is 10% less, than that the Hungarian decree provides. Using the yearly measured energy consumption data given by the inhabitant of the investigated family house, the validation of the developed dynamic building energy simulation model by TRNSYS could be also achieved with good agreement.
