Sguardi ed esperienze sulla conservazione del patrimonio storico architettonico (Book 2)

In Italy the so-called piani del colore represented a first response to the need for tools to regulate, discipline, plan, but also enhance the colour on an urban scale starting from the most homogeneous or representative areas of the city, the historical center. In this work, a method for the conservation project of finishing of historical buildings is defined, considering not only the colouring but also the historical support materials. A “Colour Plan” consists of research and investigation activities: indirectly, through historical documentation researches, and directly, through visual materials and degradations survey. The general state of “health” of the walls must be investigated examining the building techniques and the stratigraphic relationships between the various parts of the building, through the use of diagnostic methods, on-site and in laboratory. In addition the colour of every architectural element in the façade is instrumentally surveyed. The methodology intervention here presented finds a practical application in the case study of the historical center of Castiglione Olona (VA), a fourteenth century old town, renowned example of Lombard Renaissance. The purpose of this work is to propose a planned conservation project the most adequate with the specific problems, based on a thorough diagnostic approach. Furthermore, this paper defines a general management strategy aimed to reduce the overall intervention duration and costs, so that a sustainable conservation planning can be achieved. In such way, the funds raising phase is a major issue that has to be properly considered. The widest and more spontaneous participation of all the “actors” involved (both professionals figures and private owners) is also a highly desirable result to be achieved in the Colour Plan realization.
