The basis of this study are experimental results obtained on a real scale cell in controlled climatic conditions which are used to show the potential influence of radiative participation of inside air on natural convection in a room. In a second part, a numerical analysis of flow patterns and heat transfer in a twodimensional thermally driven cavity containing a participating fluid is presented. The results obtained show the influence of the radiative coupling between the walls and the fluid, and the influence of the radiative transfer inside the fluid itself on the thermal field and flow patterns obtained in the cavity.
