The school project was developed in collaboration with Michele Amorim and Endi Marley for "The Earth School Competition, Secondary School in Kafountine," organized by the NGO Kakolum in partnership with Archstroming Architecture Competitions. The proposal aimed to create a school for 400 students in the coastal village of Kafountine, using local materials and sustainable construction techniques. The approach was designed to reduce costs and minimize environmental impact, ensuring a durable infrastructure adapted to the region's climate. The project utilized the Nubian vault technique, which does not require formwork or scaffolding, allowing for faster and more economical execution.

My master’s thesis at FAUP used this project as a case study to assess the architectural feasibility of the Nubian vault in an institutional context, as this technique has traditionally been applied in self-built projects. The research analyzed the functionality of the technique, its climate adaptability, and its potential for replication. Given Senegal’s lack of basic school infrastructure, the tendency toward conventional construction, and the current climate challenges, the study highlights the need for more sustainable alternatives. The results indicated that the technique provides a viable and efficient solution, particularly when combined with reinforced concrete for structural reinforcement.

From an ecological perspective, construction with the Nubian vault significantly reduces greenhouse gas emissions and enhances carbon sequestration. The project incorporated greening strategies that optimize CO2 absorption, promoting a positive carbon balance. It is estimated that the school will become carbon neutral within 10 to 15 years, depending on vegetation growth and resource efficiency. Financially, the construction of the school cost approximately 30% less than a conventional building made of cement blocks and metal roofing, reaching a final cost of around 200,000 euros. This cost was further reduced by using local labor and accessible materials.

In addition to the technical and environmental analysis, the thesis discussed the impact of building form and orientation on environmental comfort. The project prioritized cross-ventilation, protection against excessive solar exposure, and thermal optimization of indoor spaces. The modular structure allows for future expansions without compromising thermal efficiency. The valorization of vernacular materials was also explored, highlighting their positive impact on social perception and the school’s cultural integration. As a result, the project represents a replicable model for other regions with similar climatic conditions, aligning with contemporary demands for universal education and decarbonization.
