the same goals in mind. “It is inherent in
our thinking,” says Desjardins. “The build-
ing’s envelope is the main element in the
design of the building to insure a high en-
ergy efficiency this means having a high
thermal efficiency and impermeability to
limit infiltration.” As such, the Desjardins
Expert Conseil team advises architects on
how to minimalize the thermal load in their
buildings. For example, the orientation of
the building and window selection is vital
since windows comprise a minimum of 40
per cent of the envelopes composition.
“Their properties in terms of thermal con-
ductivity and the solar heat gain coefficient
are of great importance,” says Dejardins.
