The CLIM 2000 software proposes a host architecture for dynamic, modular building energy modelling. CLIM 2000 provides a library of basic models, which in particular allows simulation of hydraulic heating networks. Unlike those oriented towards simulation of the building envelope, these models pose specific resolution problems. Owing to the modelling adopted, the elements making up the hydraulic networks require knowledge of the topology of the heating circuit. The choice of models depends on this topology. This choice is made by an expert system, here produced with the GENESIA 2 generator, executed before the global model numerical solving phase, consisting of assembly of the various basic models. Here, we propose studying the method used to solve these problems inherent in this new type of model. This approach enabled the field of application of CLIM 2000 to be broadened in relation to its initial design. Here, the modelling adopted demands pre-processing before the numerical solving phase. General modelling problems can therefore be processed independently of any numerical solving (processing of sequential data, choice of models dependent on the organisation of a graph, etc.). The solution proposed here will thus enable other problems we will encounter in the future to be answered on a case by case basis, further to specific adaptations.
