Sammanfattning
The construction industry has an
undeniable share in the global CO2
footprint and according to the UN
Environmental Programme the industry
is drawing further away from the
2050 decarbonisation pathway while
its emissions reached a new peak by
exceeding the pre-pandemic numbers
of 2019 (UNEP, Nov 9 2022). With
concrete being one of the predominant
construction materials, it contributes to
this share massively. Furthermore not
only the production of concrete but also
extraction of its components from the
planet is accelerating in a warning rate
and causing unrepairable environmental
damage.
Especially Nordic countries have high
environmental awareness and there are
many examples of sustainable buildings
responding to current needs. Nevertheless
the large scale underground structures
are still built with concrete due to
their higher requirements.
The study aims to explore the properties
of carbon neutral or even carbon
negative substitutes in combination with
alternative building methods and design
approaches. The replaced materials
jointly with a supporting design process
and construction method aim to minimise
the environmental impacts.
As location for the thesis Haga station
of Västlänken project (eng.: West Link),
a part of an ongoing infrastructural
project of Gothenburg, is chosen, which
is situated in one of the oldest districts
of the city surrounded by historical
landmarks. In addition to its touristic
appeal, according to the urban development
project the commuter traffic in the
area will increase. The thesis proposes
an exhibition area in the first underground
level of the station dedicated to
showcase these explorations and further
researches to raise awareness, while
connecting two entrances to the station
and forming an alternative path for the
commuters. The space is designed with
focus on efficiency of material use and
inspired by traditional but mostly abandoned
building technics.
