Justice-oriented, context-sensitive approaches that go beyond technocratic top-down decision-making processes can facilitate and improve the retrofit and energy transition of housing. Urban living labs (ULLs) are emerging as valuable collaborative spaces for learning and co-creating strategies. Although increasingly adopted in urban planning and placemaking, their potential to operationalise procedural justice by facilitating inclusive and accessible processes in energy renovation remains unexplored. Drawing on fieldwork notes and expert interviews, this study examines the initial phases of four Dutch energy living labs (ELLs) implemented in vulnerable neighbourhoods to support housing retrofit and energy transition projects. It analyses how they foster residents’ inclusion and connect institutional agendas with residents’ everyday practices and living environments. The findings reveal how ELLs play a strategic role in enhancing residents’ visibility, creating multistakeholder relational arenas that stimulate interorganisational learning. Researchers in ELLs mediate between theory and situated practices, facilitating energy justice implementation by challenging established professional assumptions. Flexible, locally guided forms of ELLs help address process shortcomings, supporting more socially embedded retrofit and energy transitions, and notably contribute to a) resident engagement and representation, b) technical design and performance and c) collaborative and responsive governance approaches.
