Abstract: Comparative contemplation of reference climates regarding their influence on the energetic building performance. There is a steady increase of the importance of component and building simulation as a part of a holistic building information modeling (BIM). The quality of the simulation results is highly influenced by the selected ambient climatic conditions. Currently the user is forced to use different reference climates depending on the focus of the preferred assessment. In this paper, the impact of different German reference climates on the energy consumption of a sample building is assessed. Therefor the steady state heating degree days as well as the transient heating load of the building are compared using different ambient reference climates. Finally, the results generated with the reference datasets are set into relation to the naturally fluctuations of the local climate. [ABSTRACT FROM AUTHOR]
