Auditoria and Public Halls. The preserved Architectonic Heritage, in the Perspective of Sustainability

Theatres and auditoria have only rarely been “virtuous” examples for energy use both for their peculiar space requirements and for the discontinuity of their use; such statement is even more true when such spaces are located and hosted within monumental buildings such as former churches or industrial areas; that is a quite frequent case in the Italian urban contest. To re-think critically the entire process - from political-planning decision-making to the managing phase – does represent a key step to prevent the decay and abandonment of works of great value and great architectonic and cultural significance. To that aim, three cases of architectonic and historic quality, located in Torino (Italy), are reviewed.
