Development of a Service Life Database of Building Elements Based on an International Data Collection

This paper presents a new service life database (DUREE database) for building elements, based on international service life data. The database includes 7’000 service life data, for more than 2’000 building elements. In addition, the fitting of the data to a lognormal distribution is presented. The study contributes to the increasing demand of probabilistic building LCA and LCC and provides the possibility to define statistical distributions, with a systematic way, for a large number of building elements and different levels of details (LOD), appropriate for BIM-based assessments.
