    Abstract

    This paper presents a life cycle assessment (LCA) case study of an office building. The case study investigates how the setting of free parameters (adopted from the CEN/TC 350 standards) influences the results of the building’s LCA in the DGNB certification scheme for sustainable buildings. The parameters concern the reference study period and the energy supply scenarios. Furthermore, a set of toxicological impact categories are included in the assessment to test whether the toxicological impact potentials follow the same trends as the impact categories already included in the DGNB methodology
