Abstract: the aim of the current thesis is to present a physical model with the purpose of describing the performance of a solar chimney. It has to be in contact with an enclosure allowing the airflow with the outside. This effect would be the result of the natural convection caused by the incidence of the solar radiation throughout the day. Consequently, the hypothetical cooling of the enclosure itself in summer will be studied. To do so, the dependency of the chimney’s instantaneous efficiency on different structural parameters as the length or the tilt with respect to the horizontal plane will be analysed. The model is based on the energy balance between the different parts of the chimney; a few equations which will be solved iteratively. Therefore, several magnitudes involved in the process will be determined, such as the different uniform temperatures or the air mass flow rate through the chimney
