CAN GENERAL SIMULATION MODELS IDENTIFY EXISTING BUILDING CHARACTERISTICS?
R. Enriquez, S. Soutullo, San Juan, J. A. A. Jiménez, M. R. HerasAbstract: The experimental evaluation of the energy performance of existing buildings and components is implemented usually via stochastic modelling from experimental data (Rabl 1988, Jiménez 2008, Enriquez 2008). The most popular methods, stochastic black and grey box modelling, produce predictive models and in some cases identify sucessfully the principal thermal parameters of the building. However, the models obtained are hard to generalize to other situations. On the other hand, simulation techniques are becoming popular tools used commonly in the design stage of a building to optimize its energetic behaviour. However, it is uncommon to check experimentally the validity of simulations or employ them to design, tune or optimize the buildings control systems and their operation. In this work a different approach to the identification problem is explored. It is studied the possibility of creating a general purpose simulation model for an office room and fit it to experimental data of different occupied and oriented rooms in order to identify their main thermal parameters.
