The aims of this project are to contribute to the development of educational infrastructure in rural Ghana in order to provide a better future for the next generations and to value the use of earth as a local sustainable construction material. To be successful the project is important to keep the community engaged during the workshop.
THE CLUSTER
The starting point for this project is the traditional Ghanaian clustered typology called Asante. It consists of clusters of small modules set around a common central space. In our case each cluster consists of ten modules used as classrooms. This typology produces a sense of community and belonging over the central space. Two big openings on the long sides are the main entrances to the blocks and four narrow alleys on the short sides give them more permeability.
THE MODUL
The module is conformed by two spaces: the classroom and the porch. The classroom is designed to host 24 students which can use the porch as a flexible space for multiple activities to play, rest or serve as a storage area. This will be a transitional space between the classroom and the central courtyard
THE MATERIAL
The module’s walls will be built with earth, particularly with Laterita. Why?
Firstly, this is a traditional material on the area (70% of the surrounding land contains Laterita). Secondly, is 100% recyclable, and lastly it has great climatics properties: Thanks to it is great thermal inertia, the wall accumulates heat and regulates the humidity, keeping a constant temperature during different seasons.
ENVIRONMENTAL STRATEGIES
The porch, built with wood and straws, carries out different bioclimatic functions. It surrounds the classroom to protect it from rain, noise and excess of sun radiation. The roof’s porch is displaced from the classroom’s one allowing natural ventilation and some overhead light. Cross ventilation occurs thanks to the distribution and orientation of the openings that also bring an homogeneous light to the class preventing visual discomfort.
