Abstract:
The construction industry is one of the most resource-intensive economic sectors and is responsible for a significant proportion of raw material consumption and waste generation. While sustainable strategies in construction have long focused on energy efficiency and building operation, the importance of material-related environmental impacts throughout the entire life cycle of a building is increasingly coming to the fore. Building renovation in particular represents a previously underestimated area for action, as it is characterised by short renovation cycles and a high diversity of materials.
The aim of this thesis is to analyse the significance of building renovation in the life cycle of buildings and to examine the extent to which circular economy principles can contribute to reducing resource consumption and waste generation. Based on theoretical principles and a trade-specific analysis of selected finishing trades, potential for dismantling and reuse is identified. This is supplemented by a practical investigation of a reference building using the associated service specifications.
The results show that the recyclability of building finishes is largely determined by design principles and planning decisions. Specifications prove to be a key control instrument, with which significant improvements can be achieved through targeted adjustments.
