Location: Hiddi and Dillu, Ethiopia
Organisation: NGO Abay Ethiopia
Brief: A flexible model will be needed to adapt to each space.
4 classrooms, latrines, a covered courtyard and an open courtyard, multifunctional space, kitchen, dining room or a corral.
– MASTER PLANNING
1) Space and Circulation
The cluster forms a centralised open courtyard, allowing activities, efficiency and safety to occur. Covered courtyard is designed for children to carry out sport activities during rainy days.
2) Multifunctional Space
The multifunctional space can be used for any age group. Indoor space can be extended to covered courtyard according to the needs of activities, whether sunny or rainy days.
– RAINWATER HARVESTING
Connected roofs allow the rainwater collection effectively in a large area. Roof surface area for rainwater harvesting is 700 m2.
During rainy days the rainwater from roof surface will flow to the roofs above horizontal beams (the lowest area of the roof). From there the rainwater will be guided to gutters which are connected to the underground water tank.
Rainwater stored in underground water will be utilised for the orchard and the latrine.
– CLIMATIC ADAPTATION
1) Flooding: buildings are elevated two steps from the ground in order to prevent flooding.
2) Ventilation: small openings at the top of the walls provide building ventilation.
3) Harsh Sun Impact: the Northwest façade has a cavity wall creating a thermal mass for daytime cooling and evening warmth.
– MODULAR DESIGN
1) Dimensions of Classrooms x 4 Cluster
Classroom x 4 cluster including the other requested programs is in dimensions of 36m x 36m.
2) Roof Unit
Because of the frame structure, which allows H.C.B wall underneath to be flexible for shaping the space. A roof unit is sized by 9m x 9m.
A classroom is in size of 6m x 7.8m within one roof unit, which provides the flexibility for a potential future extension on each site. Each classroom has its outdoor garden where ecological education can be taken place.
