Design brief
The school is named by the name of the largest man-made lake in Ghana - Volta. It is called by the Volta School in Ashanti Region of Ghana.
The building typology collected for this project is the classroom. On the site, there is a total of 13 units of classrooms organized alternatively with the existing vegetation. Each unit contains two classes in which each class has a capacity of 42 students.
The major scheme for the master plan is to leave the respect for the current natural conditions of the site entirely. Particularly, two large areas of palm trees will be saved for remaining the moderate atmosphere and coolness for the whole site. Besides, the domestic walkways are kept mostly to become the main circulation for the users. Hence, the area of vegetation in the middle of the site becomes the central courtyard for all students and staffs of the school.
All steps in the construction of a typical unit and other blocks are based on three basic factors – affordability, possibility, and environmental efficiency. The materials used for all architectural elements of the design have resources from nature and are entirely available on the construction site and neighborhoods such as earth for foundation and insulation walls, palm wood for door/window frames, and palm leaves of roofing. Furthermore, all traditional and regional technologies in construction are applied besides the environmental strategies to ensure that they are familiar with the local labors.
To deal with the vulnerability of climatic conditions to the buildings in this area, the passive design strategies are thought and used effectively to reduce impacts of the weather on the buildings and remain the comfort for the people, especially in hot season. These environmental solutions focus on optimum of natural ventilation for both cross- and stack- ventilation by the large overhang of the corridor, high palm leaf roof, the appropriate room depth and the openings designed for all walls. Additionally, they allow the penetration of diffuse natural light inside the building to provide a good visual environment for the students, however, still keeping the direct sunlight outside from 10 am.
For the hot dry places, the vegetation is very important to preserve the humidity and the coolness. So, an effective simple method is used that the rainwater will be reused and collected by the system of biological gutters of pebbles. This system conducts the rainwater going around the courtyards and lawns, and providing water slowly for earth and plants. By this way, the maintenance of the vegetation is very affordable and a decrease of labors.
Budget (for one class)
1. Foundation & Floor (earth, brick blocks) : $2850
2. Walling (earth) + Door/window frame (Palm timber) : $1971
3. Roofing (concrete beam, trusses by palm timber, tiles by palm leaves) : $1816
4. Fittings : $860
5. Miscellaneous (gutter by aluminium, metal chain) : $105
6. Operable doors/windows (panel of colorful polycarbonate, frames of palm timber) : $170
7. Fixed windows (palm wooden screen) : $124
8. Lighting (fluorescent lamp + aluminium shade) : $104
TOTAL : $ 8000
