The new envelope is a delicate response
to a complex problem. In developing
corrective measures for the building’s
many weaknesses, the transdisciplinary
team produced a sustainable, innovative
solution: adding a transparent glass
curtain wall to the concrete structure.
The glass casing was carefully designed
in continuity with the structure developed
by Victor Prus, the original architect,
and the mural work of Jordi Bonet,
enshrined by Prus’ protective outer shell.
Discrete and almost immaterial at times,
it reflects its surroundings and becomes
the main interface with the city, adding an
additional theatrical act in the discovery
of this significant Quebecois work.
As designed, the thin wall of protective
glass shields the Grand Théâtre from
the elements by creating a secondary,
tempered envelope housing a low-flow
heat recovery and thermal mass system.
The system is both energy-efficient and
economical. Beyond its primary function,
the new layer acts as an extension of the
original building it protects, using the
same finely tuned structural logic and
composition.
