As by 2050 the European Union aims to reduce Carbon Dioxide (CO₂eq) emissions from the building sector, this report intends to analyze the savings that can be achieved to lower the CO₂eq emissions from reusing existing concrete structures in buildings. Construction and demolition processes produce 35% of total global waste and concrete is a major material. This research is based on the real case scenario of New Dalarna University Campus in Borlänge (Sweden), which reuses 80% of the existing structural elements and integrates it into the new design of the campus.Two scenarios are analysed and compared; the first one is when the existing structure is demolished and built again and the second one is when the structure is reused and partly repaired and adapted for the new function. The method used for this thesis is the life cycle assessment (LCA), and the emissions are calculated with the One-Click LCA software. The results of the assessments show that by reusing the concrete structurere markably reduce the CO₂eq. by 98%, when it is reused in-situ, compared to the newly built structure.The study of this report not only aims to encourage companies and authorities to reuse the existing structural elements integrating them into new building designs but also, reassure that the reuse of buildings is a great alternative which allows to preserve the buildings historical aspect and time-line.
