The role of designers is shifting within a changing society, the new generation of designers increasingly want to create novel and sustainable technologies to have positive impact on the planet and its inhabitants.

In this research we explore how the needs and practices of participants in a participatory design session can be influenced to create sustainable practice-oriented concepts within a future everyday context.

The research consisted of four participatory design sessions, two intervention groups and two control groups, each consisting of two participants. The sessions were put in a designed speculative future context about summer comfort. The intervention group applied an idea generation technique to think creatively and differently about their everyday practices and the results were compared to the control group afterwards.

The findings contribute insights into a newly designed method designers could apply when designing in the context of a future everyday scenario. This includes the following subjects; the experience of the participatory design session and the differences between the intervention and control group.
