LoginNatural ventilation can be an effective measure to minimize building energy consumption and to improve indoor air quality. This study focuses specifically on buoyancy-driven single-sided ventilation design using computational fluid dynamics (CFD) techniques. Simulations are performed for a student dormitory under typical conditions of outdoor temperature, cooling load, and opening size by use of an indoor stack model and a combined indoor and outdoor stack model. The simulation results are also compared with semi-analytical solutions. It is found that the outdoor environment plays a significant role in accurately modelling buoyancy-driven flow, thereby making the combined model more appropriate and informative for studying single-sided ventilation. The results produced by the combined model are within a 10% agreement of the semi-analytical solutions.
