It differs from the vernacular architecture because in central and south Italy there were small windows on the buildings to let the minimum light possible entering to avoid overheating in summer, instead in the new constructions it is preferable to have big windows to let the light in, to reduce the electric consumptions. The two southern faces have only the balconies, without windows on the façade, they are all protected by a wooden shading system. The wood is positioned all over the building, but in particular in the southern part because, since it is not a conductor, in summer brings benefit to the building, keeping the heat out.
