This Master's thesis deals with the calculation of the primary energy demand of a single family house. In order to draw conclusions in advance about the future energy consumption, a dynamic calculation method on an hourly basis was developed. With this method, influences from the ambient conditions and the behavior of residents with the resulting response of building services can be combined.
The core of the calculation constitutes the central hot water storage tank. It assimilates the entries from the thermal solar system and the heat pump and provides the output for space heating and domestic hot water.
The calculation method has been refined using data from an existing building. To improve the accuracy of the method and to indicate errors, comparative calculations were performed according to current standards in the field of thermal insulation and building services.
