Simplified thermal and hygric building models: A literature review

This paper provides a systematic literature review on simplified building models. Questions are answered Like: What kind of modelling approaches are applied? What are their (dis)advantages? What are Important modelling aspects? The review showed that simplified building models can be classified into neural network models (black box), linear parametric models (black box or grey box) and lumped capacitance models (white box). Research has mainly dealt with network topology, but more research is needed on the influence of input parameters. The review showed that particularly the modelling of the influence of sun irradiation and thermal capacitance is not performed consistently amongst researchers. Furthermore, a model with physical moaning, dealing with both temperature and relative humidity, is still Lacking. Inverse modelling has been widely applied to determine models parameters. Different optimization algorithms have been used, but mainly the conventional Gaus-Newton and the newer genetic algorithms. However, the combination of algorithms to combine their strengths has not been researched. Despite all the attention for state of the art building performance simulation toots, simplified building models should not be forgotten since they have many useful applications. Further research is needed to develop a simplified hygric and thermal building model with physical moaning. (C) 2012. Higher Education Press Limited Company. Production and hosting by Elsevier B.V.
