Natural ventilation, Indoor ventilation, CFD, Simulation-Based Architectural DesignAbstract
In recent years, the design process in architecture has experienced significant increments arising from computational design, which allowed the exploration of design alternatives in real time based on parametric modeling. In the building's design, understanding most of the measurement systems in the context of natural ventilation could drive the decision-making process from the tests with computational simulations. This paper attempts to determine the flow pattern of natural ventilation in indoor environments under specific conditions from the CFD Ansys Fluent® R22 comprising five configurations analyzed comparatively to a control sample. Respecting the scientific reductions and using computational techniques for measurement from Aeronautics, satisfactory inferences were registered. We concluded that the diagonal positioning of the openings substantially accelerates the wind speed in indoor environments. This design strategy overrides the proposition of more openings when the intention is to increase the speed and renewal of indoor air.
