This study aims to reduce energy demand in architecture through the use of passive strategies, specifically focusing on natural indoor ventilation. Computational simulations (CFD: Computational Fluid Dynamics) were conducted, and parametric algorithms in Grasshopper were employed, applying a methodology based on evolutionary design. The objective is to optimize the design of single-family courtyard houses with cross-ventilation by evaluating how the morphology of these houses influences their performance in terms of natural ventilation. Through morphogenesis processes and evolutionary design, more than 200 morphological variations (samples) were generated, whose results allowed for the selection of the best-performing models. The most successful genes were combined in new generations to repeat the evaluations, ultimately achieving a housing model that optimizes ventilation up to 2.5 times more than the traditional courtyard house model.
