SUSTAINABLE RENOVATION
OF A BRUSSELS HOUSE:
A CHALLENGE FOR BUILDING TRADESMEN
JÉRÔME BERTRAND
CENTRE URBAIN ASBL
TRADITIONAL BRUSSELS HOUSES POSSESS NUMEROUS QUALITIES, IN TERMS OF
SUSTAINABILITY, THAT CAN BE ENHANCED DURING A RENOVATION PROJECT.
IN A CONTEXT WHERE THE MAJORITY OF WORKS ARE CARRIED OUT WITHOUT
THE INVOLVEMENT OF ANY ARCHITECT, THE TRAINING OF COMPANIES AND THE
EDUCATION OF CLIENTS PLAYS A DECISIVE ROLE.
This contribution starts by considering the advantages and constraints of the traditional Brussels
house (from the late 19th century
and early 20th century) in terms
of sustainability. This will therefore, initially, be a diagnostic type
approach. It will then address
energy renovation and heritage
through a number of examples
of works, focusing on a renovation carried out as part of the call
for Batex projects by Brussels
Environment (see p. 14), before
illustrating some of the difficulties
faced by craftspeople as a result
of the application of new requirements in terms of energy. It concludes with the issue of training
for these trades and the provision
of information intended for the
public.
THE BRUSSELS HOUSE:
A SUSTAINABLE RESOURCE
I really liked the suggestion by
Vincent Degrune to add a fourth
pillar to the three pillars that
define sustainable development
(the environmental, social and
economic aspects) to include the
cultural aspect (see p. 86-93).
It is with this in mind that I will
consider the heritage value of the
Brussels house. Figures 1 and 2
show two familiar Brussels urban
landscapes. Rue de Locht is lined
with neoclassical-inspired façades
rendered and painted in light tones.
They represent the first major phase
of urbanisation in the second half of
the 19th century. The second row, on
Rue des Pâquerettes, demonstrates
the emergence, at the end of the

century, of a new taste for exposed
materials. The facings are composed
of bricks of various colours which
alternate with bands of blue or
white stones. During this period,
with the proliferation of balconies
and bow windows, façades were
increasingly coming alive in a threedimensional sense. Nevertheless,
what
characterised
Brussels'
urban landscape at the time was
the detail in the composition, which
is reminiscent of the works of early
Flemish painters. The detail was
the starting point from which the
whole was created (fig. 3 to 5).
From the perspective of energy
consumption,
the
contiguous
nature of traditional Brussels
houses is an asset since it reduces
the surfaces from which heat is
