ARCHITECTURAL HERITAGE
AND ENERGY PERFORMANCE:
COMPATIBILITY CHALLENGES?

MONUMENTS AND SITES DEPARTMENT
THIS ARTICLE COMPRISES AN OVERVIEW OF THE ISSUES WITH WHICH THE
MONUMENTS AND SITES DEPARTMENT IN PARTICULAR, AND THE HERITAGE
SECTOR IN GENERAL, ARE CURRENTLY CONFRONTED WHEN APPLYING LEGISLATION
REGARDING THE IMPROVEMENT OF THE ENERGY PERFORMANCE OF BUILDINGS.
With recent advances in the battle to reduce CO2 emissions and
improve the energy efficiency of
buildings, the heritage sector has
been looking for a new way to deal
with architectural heritage within
that context. The assumption that
heritage and energy performance
are placed in direct opposition may
seem like something of a caricature; in many building dossiers,
the applications we are confronted
with in reality sadly do resemble
this harsh depiction of two sides
performing contradictory actions
on each other's terrain.
THE TASK OF THE HERITAGE
CONSERVATOR
Let us first take a closer look at
the role of the heritage conservationist. Essentially, the heritage
conservationist is charged with
preserving heritage; he or she
ensures that buildings, as expressions of an architectural past, of
culture and of savoir faire, are preserved. This includes preservation
of materials from the past, monuments and their valuable aspects
and facets such as decorations,
details, materials, techniques,
architecture from the various construction periods (from Gothic to
Renaissance and Eclecticism to
the late Modernism of the 1950s
and 1960s), and the preservation
of expression, concept and urban
design context. In this way, monuments are passed on to future generations as witnesses of history,
culture, science and knowledge.
Heritage conservationists guide
monuments towards their future
while battling against natural erosion and the ageing of buildings,
damage caused by natural disasters, wars or even previous restoration attempts. They also strive
to guide the monuments through
the heritage renewal, through renovations, new allocations, adaptations to styles, flavours, comfort
requirements and of course the
energy performance improvement requirements. Exactly what
is deemed valuable depends on
16 | Architectural heritage and energy performance
the monument. Sometimes it is a
unique expression, sometimes it
is the old material with a unique
historical testimony, sometimes it
is the concept or idea behind the
building rather than the materials.
The heritage conservationist's
task is supported by a theoretical framework based on the 1964
Venice Charter. The legislation
in use and under development
today also stems from this charter. The two cornerstones of this
restoration philosophy are as follows. Firstly a good knowledge of
the monument is imperative; this
highlights the importance of thorough research prior to any intervention, both historical and technical as well as any other research.
This allows us to recognise what is
truly valuable and make a decision
on how to intervene or not. The
second cornerstone is respecting
a hierarchy in the intervention.
Maintenance must always be the
top priority. If maintenance alone
does not prove sufficient, restoration and repairs are embarked
