Description
The new municipal service building is more than just a
simple warehouse – it represents the town’s strong commitment to a
self-sufficient energy supply and the careful use of natural resources. The 1,200-square-metre
roof is therefore fitted with photovoltaic modules, and all rainwater is
collected in an overground cistern. This 60-cubic-metre cistern has been
designed as an integral, and noticeable, feature of the building that also contributes
to its wind bracing. It enables the recovery of 700 cubic metres of rainwater
per year, covering the irrigation requirements of all flowers, plants and
football pitches in the municipality. The roof produces around 230,000 kilowatt
hours of electricity per year, considerably more than the building consumes. On
the interior, the technical and industrial style is toned down in favour of a
spiritual, almost sacred atmosphere. The hall is suffused with northern light,
the light preferred by artists, making it an ideal place to work, so that it is
easy to imagine the building having other lives and uses ahead of it. The
primary structure of concrete offers high resistance to the demands of the
climate and usage. It is combined with a lighter wooden supporting structure
that was produced locally in the Vosges region. In close cooperation with our
structural engineering office CAPEM, we developed a system of concrete arches
and buttresses to subdivide the main rooms. In the generous spaces in between,
the structure is completed by beams with variable moments of inertia, so-called «fish belly beams».
