The large double roof is made of two principal layers, connected by steel lattice beams. The first is made of metal panels covered with insulation and protects the building from the scorching summer sun. The second is a dropped ceiling of mineralised fibres. Air naturally flows between the two.

The structure of the roof was conceived as a large tree that shelters life underneath it and creates a cool multipurpose public space. The shape of the flying roof columns emulates a tree trunk and its branches. It strongly marks the identity of the project as a whole.

 L’Université Alioune Diop fut fondée en 2007 dans le cadre des efforts déployés par le gouvernement sénégalais pour décentraliser l’enseignement supérieur et encourager les jeunes à rester dans les zones rurales, en fournissant des programmes éducatifs adaptés. En 2012, un projet d’extension est lancé dont l’Unité d’enseignement et de recherche de l’Université Alioune Diop constitue le site principal.

Le projet

L'unité d’enseignement et de recherche de l’Université Alioune Diop à Bambey, où l’emploi de stratégies bioclimatiques pallient un manque de ressources, présente un large auvent et un mur en treillis qui protègent le bâtiment du rayonnement direct du soleil, tout en laissant l’air circuler. Par le recours à des techniques de construction locales et les principes de durabilité, le projet a réussi à maintenir les coûts et les exigences d’entretien au minimum, tout en fournissant une réponse architecturale audacieuse.

Ce qu'en dit le jury

«L’Unité d’enseignement et de recherche de l’Université Alioune Diop, avec son architecture élégante et contextualisée, constitue un exemple durable d’efficacité énergétique à faible consommation d’énergie et impact environnemental.»
«Les questions bioclimatiques, consommation d’énergie, ressources matérielles, pollution de l’eau sont à l’origine du projet et se sont révélées nécessaires à l’optimisation de l’enveloppe du bâtiment. La gestion de l’eau et la technologie des matériaux de construction sont autant d’éléments essentiels qui ont guidé la conception architecturale.
«Côté nord, le bâtiment s’organise autour d’un vaste espace ombragé qui facilite l’interaction sociale et permet une circulation linéaire. Les éléments de construction tels que les parpaings perforés possèdent une double fonction, permettant à la fois de ventiler l’air tout en réfléchissant la lumière directe du soleil.»
«Ce projet tient compte du confort, de la consommation d’énergie et de l’environnement. Il présente un design de qualité basé sur les principes environnementaux, tout en offrant des espaces intégrés au site et adapté aux conditions locales.»
«Les techniques de construction employées ici peuvent servir de prototype pour la réalisation d’autres bâtiments. Le processus de développement durable qui en découle, peut servir de modèle de référence pour la mise en œuvre d’une architecture contextuelle, respectueuse de l’environnement.»
