Architecture in the second half of the 20th century: forms of expression and the “environmental issue”
Abstract
Numerous architectural works from the second half of the 20th century, having a recognized
cultural value, turn out to be quite problematic when observed in the scope of today’s
unavoidable principle of environmental responsibility. Though representing an energy “issue”,
they are at the same time a “high-level witness” in the context of architecture, whose original
form of expression, language, and perception must be preserved as intact as possible. This
paper critically presents three interventions on architectures in Turin by Domenico Morelli
that allow us to make a series of general observations concerning the relationship between
preservation and adaptation of works from the second half of the 20th century.
