A numerical simulation of the air flow pattern in a building at constant temperature having several openings for air inlet and a chimney is presented. The modelling is based on the use of a Galerkin‐Uzawa finite element method (FEM) with quadratic elements, for reliability and cost‐effectiveness. Four different cases of ventilation conditions are investigated. Numerical results are compared to existing finite difference predictions and experimental data, and exhibit a noteworthy agreement.
