Abstract:
The aim of this thesis is to analyse the building resource passport as an instrument for establishing the circular economy in the construction sector and its potential impact on the resource efficiency of the materials used in buildings. The analysis refers to the entire building life cycle, in which the aspects of sustainability and resource conservation are of secondary importance to the status quo overall in the construction sector. Suitable software applications are then used to compile and compare results using a real reference building. The focus here is on the effects on the life cycle assessment of the building. Finally, the results are used to assess the future effects, opportunities and risks of using a building resource passport. As a result, there is often little building-related information available about the entire building life cycle, which makes it difficult to determine the recyclability of building components and materials. With the building resource passport, the potential for increasing material efficiency is better utilised, taking into account the entire building life cycle. As an information management tool for recording and documenting the building materials and resources used in a building, the efficient use and reuse of building components and the recycling of building materials can be supported in future in line with the circular economy and resource efficiency in the construction sector can be increased.
