To counteract man-made climate change, a drastic reduction in greenhouse gas (GHG) emissions is required. For the EU, this means a net reduction in GHG emissions of at least 55% by 2030 compared to 1990. Here, the building industry, with a share of around 40% of CO2 emissions (gray energy plus operating energy), is particularly challenged. Added to this are challenges such as the increasing shortage of building materials and energy sources. In the building sector, therefore, the complete switch to renewable energies, a reduction in final energy and land requirements, the use of renewable raw materials and the implementation of closed material cycles are particularly necessary. The realization of emission-free and at the same time cycle-compatible buildings, taking into account the entire life cycle, has so far only taken place in isolated research projects. Therefore, the so-called 'Circularity-Building' presented here aims at proving that fundamentally sustainable buildings can be developed and erected, which can be constructed, operated and reused emission-free over the entire life cycle, taking into account environmental energies, renewable raw materials and closed-loop construction methods. This project, funded by the Bavarian Building Industry Foundation and realized by a Bavarian construction company, serves as a showcase project that fundamentally promotes the discourse for cycle-compatible and emission-free buildings and, as a pilot project, significantly supports the widest possible imitation. With the scientific support, it is achieved that, within the framework of a well-founded analysis process, different building variants are examined on a life-cycle basis with regard to emissions, energy and recyclability, in order to select the optimal building design on this basis.
