Solar buildings are a not too much developed matter in the ECOWAS Region (15 West African countries) yet. However there are some examples of solar buildings in Cape Verde, like the CERMI Building which is a Centre for Renewable Energy and Industrial Maintenance. It’s a good example of how to save energy because of the design, the architecture of the building, natural ventilation, solar PV, solar thermal cooling for selected training rooms.
There are also innovative solar and energy efficient buildings in Ghana, such as those buildings designed by the architecture company orthner & associates. Examples, technical data and pictures can be found on the website is: http://www.orthnerarchitects.com/
In Mali there is traditional architecture done with clay, using natural ventilation, that allows the entrance of light to the interior of the building, but keeping it comfortable at the same time. The Great Mosque of Djenné, which is a large adobe building that is considered by many architects to be one of the greatest achievements of the Sudano-Sahelian architectural style, is an example.
Many further solar and energy efficient innovative buildings can be identified in West Africa, when a survey is conducted on this topic.
