Abstract The construction industry is one of the largest contributors to all global carbon dioxide emissions. This has led to the climate impact being considered among other traditional building requirements such as the load-bearing capacity and the financial aspect. For this reason, there is a generous number of studies that analyze the climate impact generated by individual building materials and complete buildings, especially apartment buildings. However, there is a lack of information regarding the climate impact caused by structural systems and studies that make comparisons among these. This thesis initially implements an investigation that concludes in four relevant structural systems capable of being used in the construction of future preschool buildings, and that are applicable in the Skanska project ABCD-preschools. Those are later on analyzed through appropriate Life Cycle Assessments which in turn produce data that makes it possible to create a simple and effective tool to assess and evaluate structural systems for future buildings. The results obtained conclude that structural systems contribute to a remarkable share of the total climate impact produced by preschool buildings. The structural systems’ climate impact might nevertheless vary depending on the type of structural system that is utilized. This thesis culminates in conclusions and recommendations which function as tools for project developers to simplify the design choices of structural systems regarding their climate impact.
