On the Imaginary Accuracy of the LCA on the Basis of the Houseboat in Hamburg (Holistic Approach)

To our knowledge, for the first time in the history of the life cycle assessment, the LCA analysis of the houseboats used for residential purposes has been conducted while testing a new software program eLCA in its Beta version. In cooperation with the Coop Waterhouse GmbH and with the Architektenbüro PlanWerk, the houseboat Swan, due to its extraordinary solutions for energy supply, has been chosen for the first attempt at analysing uncertainty in its LCA with the focus on the energy supply components as well as on the energy input. Results discuss energy usage, being responsible for the half of the total CO2 e-emissions, and its uncertainty with regards to the next 50 years of the houseboat's lifetime.
