| Primary School in Gando / Kr Architecture Architects: Kr Architecture Location :Gando, Burkina Faso Category:Schools Architect in Charge Diébédo Francis Kr Client Schulbausteine fuer Gando / Gando Village Community Area 310.0 sqm Project Year :2001 Photographs Sim eon Duchoud As a native of Burkina Faso, Francis Kere grew up with many challenges and few resources. When he was a child, he travelled nearly 40 kilometers to the next village in order to attend a school with poor lighting and ventilation. The experience of trying to learn in this oppressive environment affected him so much that when he began to study architecture in Europe, he decided to reinvest his knowledge towards building anew school in his home village. With the support of his community and funds raised through his foundation, Schulbausteine fuer Gando (Bricks for Gando,) Francis began construction of the Primary School, his very first building. The design for the Primary School evolved from a lengthy list of parameters including cost, climate, resource availability, and construction feasibility. The success of the project relied on both embracing and negating these constraints. In order to maximize results with the minimal resources available, a clay/mud hybrid construction was primarily used. Clay is abundantly available in the region and is traditionally used in the construction of housing. These traditional clay-building techniques were modified and modernized in order to create a more structurally robust construction in the form of bricks. The clay bricks have the added advantage of being cheap, easy to produce, and providing thermal protection against the hot climate. Despite their durability, however, the walls must still be protected from damaging rains with a large overhanging tin roof. Many houses in Burkina Faso have corrugated metal roofs which absorb the heat from the sun, making the interior living space intolerably hot. 63 The roof of the Primary School was pulled away from the learning space of the interior though, and a perforated clay ceiling with ample ventilation was introduced. This dry-stacked brick ceiling allows for maximum ventilation, pulling cool air in from the interior windows and releasing hot air out through the perforated ceiling. In turn, the ecological footprint of the school is vastly reduced by alleviating the need for air-conditioning.

Fig. 59 – Bihar Village settlement The typology demands a strong constructional material which can withstand the water flow as well as the wind flow, as well as giving a vernacular look according to surrounding site context. People living in rural area usually are unable to adapt new technologies and materials easily. They are more comfortable in their local surrounding materials. Use of fly ash bricks is practiced due to high strength, practically no breakage during transport and use. Due to uniform size of bricks mortar required for joints and plaster reduces almost by 50%. Fig. 60 – Fly Ash Bricks 65 • Advantages of Fly Ash Bricks It reduces dead load on structures due to lightweight kg, dimension 230 mm X 110 mm X 70 mm Same number of bricks will cover more area than clay bricks High fire Insulation Due to high strength, practically no breakage during transport and use. Due to uniform size of bricks mortar required for joints and plaster reduces almost by 50%. Due to lower water penetration seepage of water through bricks is considerably reduced. Gypsum plaster can be directly applied on these bricks without a backing coat of lime plaster. These bricks do not require soaking in water for 24 hours. Sprinkling of water before use is enough. It is only good for the places like subtropical area or area where climate is warm because it doesn't absorb heat. But during cold it is not helpful. • Disadvantages Mechanical strength is low, but this can be rectified by adding marble waste or mortar between blocks. Limitation of size. Only modular size can be produced. Large size will have more breakages. Download 5.52 Mb. Share with your friends:
