Workshop the Kiwanda

The Kiwanda


“Kiwanda” is Swahili for workshop. At the Kiwanda WOT members test new techniques, fix and carry out maintenance on the properties, keep demonstrations, lectures and a lot more. The workshop has a large number of special homemade tools.

The building is designed according to the passive solar energy principle. This ensures the building stays warm in the winter and cool in summer. This is how
it’s done: (see diagram).

Passive Solar Energy Principle

The air conditioning of Kiwanda
1. The heat of the sun enters the building through double glazing whitch are facing south.
2. The heat of the sun warms the inner side of the building and the floor.
3. The excellent insulation of the building (20 cm thick) keeps the heat inside.
4. Overhanging eaves keep the sun out in summer. In the winter, when the position of the sun is low, the sun will shines trough the eaves.

Applications

The principle of passive solar energy is used in other buildings too, like hospitals in high altitude areas in developing countries. During the day there is plenty of sunshine, but at night the temperature drops significantly. By appling the passive solar energy principle less (rare) firewood is needed to warm the building.
