Abstract: THis paper investigates the integration of CFD in computational and parametric design and its potential in driving the optimization of the natural ventilation performance of buildings, using as a case study the courtyard spaces of the typical multistorey buildings in the historic center of Athens, Greece. The study employs a multi-scalar simulation approach and shape optimization techniques to assess the potential of using CFD to drive the design of retrofitted membranes that enhance the natural ventilation of the unused courtyards. By parametrically modeling a membrane componenton a representative courtyard case and using a Genetic Algorithm (GA) optimization along with a Fast Fluid Dynamics (FFC) CFD solver that allows for fast inerative CFD simulations, the study aims to produce localized retrofitting interventions to increase the air quality of the courtyards and the ventilation performance of the buildings.
