Neo-Vernacular Architecture in Nawdéba Country in Northern Togo: Analysis of Elements of Sustainability, Vulnerability to Climatic Hazards and Thermal Comfort of a Social Hall at CIDAP (Centre International de Développement Agro-Pastoral)

Due to rapid urbanization, climate and socio-economic change, vernacular architecture in the Kara region of Togo is now facing mutations that threaten its existence. In the Kara region, new forms of housing, inspired by ancestral building practices and green technologies, are emerging as neo-vernacular architecture. This study aims to evaluate the overall performance of the CIDAP social hall, which is considered a model of neo-vernacular architecture. Through a series of both qualitative and quantitative tools, including the VerSus tool, the PTVA method and the calculation of the temperature difference ratio (TDR), the CIDAP social hall was analyzed regarding the criteria of durability, vulnerability to climatic hazards and thermal comfort. This work indicates that this building achieves a sustainability score of 88.33%. In terms of vulnerability to climatic hazards, the vulnerability index is around 0.392 for heavy rainfall, 0.389 for high heat and 0.309 for strong wind hazard. For thermal behavior, the TDR is of the order of 0.634. All these results reveal a satisfactory performance of the CIDAP social hall in terms of durability, vulnerability and thermal comfort.
