Design-oriented coupling of system models and spatial models crossing multiple scales for energy simulation in building retrofitting

Abstract

Early phases of building design and retrofitting require quick energy analysis and decision. However, complexity first caused by the spatial effects of radiation and second by the dynamic thermal behaviour requires advanced modelling and computation technologies. To achieve quick-responding and sufficient accurate analysis results, this paper describes an approach of coupling two model types in a design-oriented way: First, a spatial model serves to analyse the radiation behaviour of the façade of a geometrically complex building body; second, a simulation-enabled systems model represents the dynamic behaviour by selected rooms with adjacent façade at a lower scale. Due to early design phase, the models are only partly simulation-enabled and a static coupling is used instead of a run-time coupling. Moreover, the paper includes strategies for model interaction and validation. A study for the use of renewable energies in the retrofit of the hospital Ingolstadt illustrates the application of the method.
