ADAPTATIONS TO CURRENT ENERGY AND

LE LOGIS AND FLORÉAL IS A GARDEN CITY THAT SHOWS US AN INTERESTING
INSTRUMENT FOR COMBINING CULTURAL VALUES AND ENERGY NEEDS.
TWO ASPECTS WILL BE ADDRESSED HERE: THE MANAGEMENT PLAN AND
THE FINANCIAL ASPECT OF THE ENERGY SAVING MEASURES EMPLOYED.
OPTIMISING THE ENERGY
PERFORMANCE OF LISTED
HERITAGE: AN EXERCISE
WITH IMPACT
The title of this contribution is:
"Adaptations to current energy
and comfort needs". The word
"needs" instead of "standards" has
been chosen deliberately. Through
energy measures that conform
with heritage, the Beheersplan voor
Erfgoed (Heritage Management
Plan) of the Le Logis and Floréal
garden city is striving to fulfil the
need for efficient energy consumption in the most optimal manner.
"Optimising" is the key word here:
it is an exercise in balancing the
potentially conflicting interests
of the heritage, cost price and
performance. The investment to
energy performance ratio is key to
ensuring maximum energy savings
within a limited time frame (20 to
25 years). Within a limited amount
of time, the financial means must
be found and invested in order to
improve the energy performance
in the majority of houses. Only
then can the largest global energy
savings be realised within this time
frame.
The Le Logis and Floréal garden
city is large. It is a complex of two
garden cities, situated in section of
the Brussels periphery built up in
the 20th century, approximately six
to seven kilometres from the city
centre. There are currently approximately 540,000 residences in the
Brussels-Capital Region, of which
(only) ± 8% are social housing

residences (fig. 1). Between 1920
and 1940, approximately 125,000
houses were built in the Brussels
municipalities, 9,000 of which were
social housing residences. 4,000 of
these have fewer than three floors,
including the Le Logis and Floréal
listed houses. With these figures,
I am trying to give an idea of the
impact the conclusions of the
management plan can have. About
4,000 social housing residences in
the Brussels-Capital Region are
structurally and technically comparable to the Le Logis and Floréal
listed houses, not to mention the
non-social housing residences
of the same type (approximately
40,000).
