231: Permeable Facades and Daylight Performance Simulations: A Parametric Approach To The Distribution of Solid and Void In Cobogós

This paper presents a parametric design approach for adaptive facades using cobogós, traditional Brazilian perforated elements. The study integrates parametric modeling and environmental performance simulation to investigate how variations in geometry and module distribution affect daylighting, glare, and solar radiation. A reusable algorithmic structure was developed in Grasshopper, enabling the rapid generation of multiple formal alternatives based on variable parameters. Three configurations were selected and tested using Climate Studio in a room with northwest orientation located in a hot and humid bioclimatic zone. Results indicate that the distribution of solid and void elements has a significant impact on visual comfort and daylight autonomy. This approach supports data-informed decision-making during early design stages and demonstrates the potential of combining vernacular architectural references with digital tools to create responsive and energy-efficient façades. Although the study is limited to a single spatial scenario, the methodology can be adapted to other contexts and environmental demands.
