Adaptation of Environmental Assessment to PSS Specificities: Heating Appliance Case Study

This article presents a method for evaluating the environmental benefits of implementing Product-Service Systems (PSSs) and Smart PSS with application to the heating systems field. The proposed PSS-oriented life cycle assessment method aims at addressing the specificities of PSS and Smart PSS, representing PSS variety and dealing with uncertainty sources resulting from the PSS context. Besides environmental analysis, the method supports decision-making by comparing different PSS scenarios. This study focuses on the challenges of a generic configuration of the life cycle assessment method and the rigorous handling of uncertainty sources, while an industrial case study reports a real case of PSS design decision-making.
