This study explores the potential of parametric façade openings to enhance natural ventilation and reduce cooling loads in high-rise office buildings. These buildings often experience stagnation zones on the windward façade, typically at mid-height, where airflow divides upward and downward. Focusing on the floor intersecting the stagnation point, the study investigates how aperture design and spatial distribution can optimize airflow and thermal comfort during warm seasons. A multi-stage methodology was employed, combining CFD analysis (ANSYS Fluent) to identify façade pressure zones, with seasonal energy simulations conducted in EnergyPlus through the Honeybee interface, and generative parametric modeling in Grasshopper. Various hexagonal aperture configurations were assessed based on air change rates (ACH), operative temperature, and cooling energy use intensity (EUI). The results indicate that aperture distribution has a notable influence on ventilation performance and indoor comfort. Among the four tested configurations, the edge-to-center (EC) scenario, which represents a gradient distribution where the size and porosity of openings increase from the façade edges toward the center, achieved the highest comfort percentage and a notable reduction in cooling EUI compared to the least effective scenario. These findings demonstrate that strategic, static aperture design can effectively balance passive airflow and thermal comfort without relying on complex dynamic systems, offering a scalable solution for climate-responsive façade strategies in high-rise buildings.
