Alles unter einem Dach! Die Baumstützen leiten sich vom Wald ab. Die Photovoltaikanlage über dem Leichtdach gilt als eine der größten in ganz Österreich.

R educe, reuse and recycle – this stands for the environmental conscience of western
consumer societies. The fact is that there is more rubbish than ever before! Active
strategies for preventing waste, upcycling and cradle-to-cradle are to counteract this.
Recycling centres make a start by collecting and separating materials and resources.
With the Blumenegg service centre in the Vorarlberg community of Thüringen,
Hammerer Architekten designed an economic-environmental showpiece. The architects
from Ludesch planned the building where day-to-day recycling materials, problem was-
ter, green cuttings, branches and building rubble are deposited as homage to the local
mixed forest. Since about 7,000 square metres of forest had to be cleared for the con-
struction site, as a compensation measure, the builders committed to reforest open spa-
ces and to restore mixed-forest cultures. The architects reforested with the architecture.
Regional tree species – fir, spruce, beech, ash, pine and arolla pine – characterize the
elongated structure, not only visually but also olfactorily. “When entering the building,
Grundriss Erdgeschoss • Ground floor plan one is welcomed by the smell of wood”, the architects explain. Under the large roof and
next to the collection of recyclable material, which is open on three sides, are the buil-
ding control department and the building yard as a compact, two-storey volume. They
were both designed as wooden-frame constructions. The false ceiling consists of
Brettstapel elements. Regional woods cover the interior walls of the building control
department. A comfortable atmosphere was thus produced which perfectly suits the
location in the midst of nature. Unlike in the building control department, in the buil-
ding yard the floors, walls and ceilings consist of formaldehyde-free glued, polished OSB
panels. The architects had all the furniture made of untreated silver fir in solid wood.
A local carpenter crafted the seating furniture. Translucent foils with motifs of the origi-
nal mixed forest add fresh green colour to the inside glass doors and –walls. An evident
reference to nature and a strong contrast to the wood species used for the interior fur-
nishing were thus created.

The façade as well consists of wood and wood derivatives. Fibreboards serve as the
insulating material; the cladding consists of rough-sawn pine boards. The envelope is
designed in such a way that it meets the passive-house standard. All the surfaces were
left in their natural state. With its construction, the generous shed roof protects the exte-
rior components from direct weathering. The lightweight roof is supported by tree-like
wooden columns which make it look as if floating. The supporting structure is econo-
mically optimized as to the spans and the materials. It was thus for instance possible
to use laminated timber instead of solid wood. Photovoltaic modules cover the entire
roof surface. This is considered to be one of the largest pitched-roof installations in
Austria and to reach a simulated annual electricity yield of about 310,000 kilowatt
hours. The people of Ludesch and Thüringen are able to fill up with energy right at the
