Black-box modeling of buildings thermal behavior using system identification

Abstract In this paper the modeling of buildings thermal behavior is studied. The main goal is to develop a modeling procedure that can be used at different scales (a thermal zone, a floor or a whole building) and on different buildings. The scalability of the chosen black-box model structure is first assessed; simulation experiments are then conducted in order to test if the modeling procedure is reusable. As these tests are hardly feasible in practice, a real university building is first modeled using an energy simulation software. This model is then used to validate the proposed approach.
