Double Face 2.0 Few architectural works draw aesthetic advantage from technical aspects; technology is often seen as a constraint limiting creativity rather than inspiring principles that become part of the design identity. With the design of the novel type of Trombe wall system, we aimed to combine a high technical performance witht its engineering performances, demonstrating the value of an integrated design identity.

DOUBLE FACE 2.0The Question
Research
Question:
How can we
design a building
product for
passive climate
regulation in which
the engineering
performances are
part of its identity?
Research Method:
Research through
design with a
novel Trombe wall
as case.
Design component:
A system in which the
functioning of thermal
mass is part of the
identity of the product
Technological
component:
A system that is
lightweight, translucent
and has high levels of
adjustability to tune it
to the specific
conditions and needs
at hand
Technical
constraints
form design
drivers
Ultimate goal

How can surface texture be optimised for exposure
to solar radiation, to internal IR radiation and to
convective heat transfer?
How can surface texture contribute to the design
identity of the product?

Also in research through design or design-
related research, it is important to dissect the
problem into smaller chunks!
