Some good news - "‘We don’t need air con’: how #BurkinaFaso builds #schools that stay cool in 40C #heat" - Architects use local materials and merge traditional techniques with modern technology to make schools and orphanages cool, welcoming places.
The Noomdo orphanage was another of his projects. “The Kéré building provides us with good thermal comfort because when it’s hot, we’re cool, and when it’s cold, we’re warm inside,” says Pierre Sanou, a social educator at the orphanage near the city of Koudougou in the Centre-Ouest (centre-west) region of Burkina Faso. “We don’t need air conditioning, which is an incredible energy saving,” says Sanou. Temperatures in this region of the world remain at about 40C (104F) during the hottest season.
“Kéré builds with local materials from our territory like laterite stone and uses very little concrete,” says Sanou. Kéré’s buildings in Burkina Faso are earthy. They start from the ground and take into account that concrete is a material that needs to be transported to the site, is much more expensive and generates waste. “They are permeable buildings that seek the movement of natural air and protection from the sun. For example, they are built with very strong walls and very light roofs so that the cool air that enters from below pushes the hot air out from above,” says Eduardo González, a member of the Architecture School of Madrid.
One particularly ingenious innovation is his use of the ancient idea of raised and extended metal roofs. The rooms of Noomdo are covered by a shallow barrel vault resting on a concrete beam but with openings. Above, a metal plate protects the roof from direct sunlight and rain. Additionally, it lets out the hot air. González says the technique can be found in the vernacular architecture of the Persian Gulf. In Burkina Faso, he says Kéré integrates it into his projects and “gives this technique a contemporary image”."
