ENGINEER, PARIS URBAN PLANNING AGENCY
THIS STUDY, COMMISSIONED BY THE BRUSSELS-CAPITAL REGION, STEPS OUTSIDE
THE WELL-TRODDEN SCOPE OF BUILDING-CENTRIC ENERGY STUDIES AND
INSTEAD TAKES A SYSTEMS-WIDE APPROACH. IT INCLUDES PARAMETERS USUALLY
IGNORED BY THIS TYPE OF WORK AND QUESTIONS PRACTICES CENTRED ON THE
APPLICATION OF STANDARDS.
This study, carried out at the
request of the Brussels Region,
was finalised in 2012. We were
asked to apply a method that we
had previously trialled in Paris to
evaluate the thermal capacities of
old buildings and to incorporate it
into the research currently underway regarding improvement of the
energy efficiency of Brussels' architectural heritage. The full report
is available on the website of the
Monuments and Sites Department.
This presentation is a summary
of our work. I will firstly return to
the working methodology, as well
as the three scales of assessment
of the problem that we took into
account: region; city; and building.
I will not spend a lot of time on the
first as it was covered in the presentation on the EPB (see pp. 10-15).
I will then focus on issues related to
urban forms before coming to those
relating to buildings.
THE BROAD OUTLINE
OF THE METHODOLOGY
We are, in the medium term, facing
a dual challenge: supplies of energy
for urban systems, dependence
on which will have to be reduced,
and climate change, which means
reducing greenhouse gas emissions and adapting the territory to
this change. In order to respond to
these issues, Europe is proposing a
regulatory mechanism ("3x20") up
to 2020. Application of this mechanism generally passes from the
European Union to the country or
region that then applies it directly

to the building. This means that
the energy question is rarely considered at district level. However,
before working on a building, it
is important to consider its direct
environment, to think about the role
it plays in relation to its neighbours.
It is therefore this method that we
favoured in our approach.
There are two characteristics of
our work: it is exploratory and
illustrative. Exploratory, as it
opens up avenues that include
energy-related elements but which
are absent from the regulations.
In this way, we are trying to apply
a method that goes beyond simply taking the regulatory standards into account and enables us
to expand the research. It is also
illustrative as the purpose of this
