This paper discusses knowledge sharing through scenario development as applied in the interdisciplinary and international research project uVITAL. It focused on user-oriented upgrading of the social housing stock. The aim was to gain deeper insights into the specificities and commonalities of the four country case studies involved. Two online workshops, which included various steps for scenario development, were particularly important during the COVID-19 pandemic when face-to-face exchanges were not possible. A Miro whiteboard was very useful as a technical communication and collaboration tool. This paper outlines the benefits and challenges of scenario development to facilitate communication and collaboration between researchers from different disciplines and national and cultural backgrounds, particularly in online and hybrid settings. The well-structured process of scenario development was an important step in the project, moving from passive to active knowledge sharing. This included issues of content, geographical and cultural diversity and methodological openness.
