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 couplingbetween the different phenomena. A full-scale DSF has been experimentallystudied in summer configuration with different airflow rates through the airchannels of the façade and for different angles of the solar shading devices.First the numerical modelling has been validated using the experimentaldata. Then, The model has been used to study the influence of airflow ratesand blades angles (Venetian blind) on heat transfer in DSF
