Nuovi usi per edifici esistenti e reversibilità degli interventi

The aim of the intervention on the built heritage is to extend the building’s life-cycle, preserving, the matter and its cultural/historical role. To pursue this objective, the adaptive-use (input of new functions) represents a strategic element to assure continuous management and maintenance of the buildings by the users themselves. However, the input of incompatible uses has, always, involved alterations of the spatial configuration of the pre-existence, by highly transformative interventions that have produced, moreover, considerable loss of matter. The choice of new functions must be made, therefore, after a preventive evaluation of compatibility. This paper explains the function of constructive knowledge in the analysis and evaluation on existing buildings, focusing on the physical status and promoting investigations to recognize its technological features and the bonds that have to be respected. The studied cases underline a continous research of technological solutions that aim to guarantee the new function’s settling in reversibility conditions of the intervention.
