I. Abstract
Traditional African architecture has long utilized high thermal mass to combat extreme heat. However, modernizing these forms requires a precise integration of Aerodynamics (ventilation) and Material Science (thermal lag). This study analyzes a contemporary Sudano-Sahelian ecosystem, demonstrating how the synergy between curvilinear Compressed Earth Block (CEB) walls and a decoupled, timber-slat "Parasol" roof system can eliminate the need for mechanical cooling in extreme climates.
II. Site & Geometry: The Logic of the Curve
As seen in the Overall View, the structure rises organically from the savanna, utilizing a village-like compound layout that encourages localized wind acceleration.
Geometry & Self-Shading: The undulating, curvilinear form of the primary volumes is a tactical response to zenithal sun exposure. As shown in the Self-Shading analysis, the curvature ensures that at any given hour, a significant percentage of the building's facade is protected by its own shadow, drastically reducing the "Solar Fraction" or the total amount of radiant heat hitting the thermal mass.
