The formal strategy in the design for the Innovative Bioclimatic European School by Atelier3AM, which won the third prize in the international competition, is based on the strong contrast of materials, and propelled by the duality of opaque/transparent. Inspired by the courtyard typology, their design creates a cluster of three separate courtyard buildings defining each educational unit, and connected by a central square. This objective was confronted by the physical site constraints, as well as by opportunities presented by sensible solar orientation and the channeling of the predominant winds.
