Normative Rahmenbedingungen für zirkuläres Bauen in Bayern

Abstract

Normative framework conditions for circular construction in Bavaria. The building sector is one of the most resource- and emission-intensive economic sectors in Europe and is at the heart of current climate protection and resource efficiency strategies. Considering the European Green Deal, the amended Construction Products Regulation (CPR) and the revised Energy Performance of Buildings Directive (EPBD), the EU is placing increased emphasis on circular construction methods. Germany is implementing these requirements through the Building Energy Act (GEG), the Circular Economy Act (KrWG), the National Circular Economy Strategy (NKWS) and technical standards such as DIN SPEC 91484. Bavaria is also making use of federal flexibility and developing model approaches with the Building Type e, innovative waste management concepts and the discussion about its own CO<inf>2</inf> shadow price. This paper systematically analyses these regulations and initiatives and highlights interactions and existing challenges. It becomes clear that the consistent integration of EU requirements, national law and regional innovations is key towards a successful transformation to a circular construction industry. The binding implementation of instruments such as DIN SPEC 91484, digital product passports, and clear goals as set out in the GEG, as well as transparent liability rules, are necessary to strengthen reuse and the circular economy, particularly when dealing with existing buildings. A CO<inf>2</inf> shadow price can provide decisive momentum for sustainable construction methods.
