The present paper presents a numerical modelling of a double skin façade (DSF). The model developed includes a zonal model approach for the mass transfer based on the pressure difference in the DSF. The radiative and convective heat transfers are also taken into account to obtain a global coupling between the different phenomena. A full-scale DSF has been experimentally studied in summer configuration with different airflow rates through the air channels of the façade and for different angles of the solar shading devices. First the numerical modelling has been validated using the experimental data. Then, the model has been used to study the influence of airflow rates and blades angles (Venetian blind) on heat transfer in DSF.
