Abstract:
This thesis deals with the EU Taxonomy Regulation, the construction and property industry and the Brownfield and Greyfield resource. As part of this study, a comparison is made with other common sustainability certificates. The effects of the EU Taxonomy on property valuations are also considered. In this context, the potentials and challenges of brownfields and greyfields are analysed. The potentials include the reduction of land sealing and new construction-related CO2 emissions. Challenges include high redevelopment costs and contaminated sites. Greyfields also contribute to material and waste savings through the continued use of existing buildings. It has been established that a property or existing building must always be subjected to individual due diligence in order to determine whether a refurbishment or a new build is more sustainable. The expert interviews conducted make it clear that applying the taxonomy to brownfield and greyfield properties is possible, but poses a challenge as the focus is increasingly on new builds. This can lead to misjudgements, making new buildings appear more sustainable than existing buildings. Nevertheless, the taxonomy is recognised as an important and future tool for assessing economic flows. However, its practical application is controversial, as companies are currently using standard certificates such as DGNB.
