Abstract
The historical reconstruction shows how the industrialization of the schools building sector, was developed in Italy far from the corresponding European experiences. In fact, although the school building sector represented in Italy the most actual tender to stage a general process of industrialization of the construction process (for temporal extension and scale of production), the fragmentation of the planning horizon forces the outcomes on a small-scale production. The industrialization of building systems was, thus, deeply related to the single realization (or a small group of buildings). Today, this fact underlines the need to deal “case by case” (through the knowledge of facts and buildings) the actions due to preserve the buildings heritage.
