It might look like the exterior is plastered with clay but this
is a lime plaster with a local mineral pigment. Lime is used
externally to protect the dome from rain. A clay plaster exterior
would wash away leaving the earth bags vulnerable. Domes in arid
and semi-arid climates might not need a protecting roof but in regions
like this
where there is significant rainfall a roof is needed.
In this region of
Zambia the hottest daytime temperatures are around 37C (99F)
and the coldest evening temperatures about 10C (50F). The
windows have a very simple frame, no glass, just mosquito nets. In the hot summer days it's a
cool place for the village children to learn and play. |
