A finite element investigation of the ventilation conditions in a heated building in which the flow is characterized by the existence of a strong effect of natural convection at high Grashof number is presented. The computation of the velocity and the temperature pattern is performed in an intertwined manner, the coupling being performed by a time stepping technique. The proposed solution strategy allows computations at a very reasonable cost. Numerical predictions are compared to experimental data, and exhibit a very good agreement for the velocity field and a fairly good agreement for the temperature.
