Close a door to open a window: Unpacking strategies and know-how in making comfortable.

Together with 11 lower-income households, we explored how assumptions embedded in domestic energy interfaces match their needs, expectations, and everyday practices around domestic energy use and comfort. Catalyzed by cultural probes, residents (1) shared the diverse strategies and know-how involved in making themselves comfortable, (2) offered arguments for their everyday futures, and (3) explained what we can learn from them. A first tentative definition of energy interfaces opens the door to what we consider interfaces, how they support developing know-how and how they co-construct everyday practices. Residents’ resourceful solutions elicit reflections on what is considered valid participation in the energy transition. From the findings, we synthesize alternative starting points for the design of energy interfaces: We outline design opportunities to expand the (un)comfortable by revisiting comfort as fluid and multi-sensory. Furthermore, we sensitize how design can build on residents’ existing strategies for making comfortable, rather than replace them.
