supplemented by round-timber columns – the floors had temporarily been supported
by the debarked spruce trunks in front of the façade during the conversion. Like the
existing concrete columns, the timber columns as well manage to visibly impress.

Ecological responsibility

In addition to the design-defining expressiveness of the existing structure, ecological
sustainability also motivates the careful handling of the existing building. By reusing Grundriss 5. Obergeschoss • Floor plan level +5
the old structure, 42 percent of grey energy can be saved. Thanks to the photovoltaic
system and the groundwater heat pump, two thirds of the total energy consumption is
self-sufficient. Ecological aspects were also taken into account when dismantling other
elements, such as steel supports and trapezoidal sheeting. They were neatly separa-
ted, fed into the recycling industry or, in the case of the trapezoidal sheet metal, even
reused in other buildings. Looking to the future, the issue of dismantlability also plays
a special role. For example, a self-supporting balcony construction made of standard
metal profiles bolted together was added in front of the building. Furthermore, the
fixtures in the flats are all non-load-bearing – the resulting flexibility of use means that
the building can be converted back into a warehouse or a newly designed office block
if required. In winter, the living space is heated by underfloor heating and in summer,
the system utilizes the temperature difference between the indoor- and outdoor envi-
ronment to cool the building. The roof of the building is almost completely covered
with a 150 kWp photovoltaic system. Längsschnitt • Longitudinal section
