Guiding Principles for Co-Creation and Collective Learning in Living Labs: Insights from Designing Physical Activity Interventions.

The KliMate project used the co-creative living lab approach to develop a multimodal intervention that supports older adults in achieving international physical activity recommendations while considering personal and climate-related factors. Participants were involved in the co-design of an App and analogue exercise formats. Based on the project's iterative cycles, this study shows how co-creation and collective learning influenced each other. Guiding principles - such as regular exchange within the consortium, concrete proposals as a basis for co-creation, flexible co-creation methods, and the transformation of open questions into new learning challenges - underline the value of methodological openness in future living labs. The central finding and main contribution to the existing literature is the importance of concrete proposals as triggers for critique, rejection, and iterative development.
