Gütesiegel für Rechenergebnisse zum thermischen Gebäudeverhalten? Genauigkeitsanalyse von Programmen und Anwendereinflüsse

Simulation programs for the prediction of the energetic and thermal behaviour of buildings are more and more frequently used at the design stage. Often, it is hardly possible to check the accuracy of the building energy balances and temperature courses that are calculated with such tools by making more estimations. Due to the great number of programs, in particular with regard to their complexity, systematic capability and credibility checks are required for such tools. This report deals with the various possible test methods. A test method developed in an IEA-project is introduced. This method can be employed for validating newly developed programs. The impact of user related errors and incorrect input on the energy balances of buildings is demonstrated with an example. The need of a minimum level of quality insurance is explained.
