Abstract:
This thesis analyses the consumption and flow of resources in German concrete construction. The aim is to find out to what extent and in what dimensions the individual components of concrete are consumed, where they come from, what energy is required during production and how high the emissions are. This is followed by optimisation potential. This includes how resource consumption can be minimised, for example through the use of substitute materials, leaner construction methods and/or the use of recycled materials. Another focus of the optimisation potential lies in the minimisation of greenhouse gas emissions, which is often only possible through new technologies, which entail other disadvantages such as increased energy requirements and higher costs. Finally, a comparative calculation is carried out on a hotel building in order to demonstrate the savings potential in terms of both mass consumption and energy consumption. This compares classic reinforced concrete construction with modern carbon concrete construction. The CO2 emissions and CO2eq emissions are also considered, whereby a reduction in emissions is recognisable, as with the mass and energy requirements.
