Informing architectural design processes in a circular economy - the quantification of circular construction
The construction sector contains great potentials to contribute to our society's green and circular transition since the construction sector is responsible for the emission of 40% of all greenhouse gases and produces 40% of the waste generation. Several political initiatives have been adopted in recent years to accelerate a sustainable transition of the construction sector, such as the European Green Deal from 2020 and the introduction of Danish requirements for CO 2 limits and mandatory LCA calculations for new construction from 2023. However, the transition occurs very slow and large scale applied circular and sustainable principles are still only represented in very few buildings. Therefore, there is a need to generate more knowledge and awareness about the potentials for implementing circular economy in both new construction and in the existing building stock. Through case studies, data mappings, analyses, and collaborations with industry and public administration, this project has investigated the circular potential in the existing building stock by focusing on demolitions, lifespans, and circular design strategies. Through data mapping, several Danish registers for building data were identified. The data mapping showed that there is generally little knowledge about the material composition of the existing building stock. The material composition of Danish building typologies was investigated by collecting pre-demolition audits submitted to the municipality, which were analysed via material flow analysis. However, it turned out that the data quality of the pre-demolition audits was too low to determine the material composition, so it was impossible to make accurate material estimates for similar building typologies based on the current data. Thus, an alternative parametric model was tested based on data from historical typology studies of the most commonly used building parts in existing buildings. A comparison showed that the parametric model could provide more accurate material estimates if extensive ...
