An urban eco-friendly and energy efficient impact in Parma, for the expansion project of the Cariparma Crédit-Agricole Cavagnari Headquarters. A large park: the green heart. Bioclimatic buildings applying the energy strategy “minimum, simple and green”. New volumes, generated from the geometry of the original settlement, are placed along the area’s perimeter in order to define and leave a large green space free in the centre. Green is not used just for landscape and environment value, but as summer microclimates generator too.
