Collaborative project between Nottingham Trent University, Nottingham Energy Partnership, and community members to develop an accessible eco-feedback interface. First, the research team conducted an online survey questionnaire with 151 respondents with distinct socio-economic characteristics and environmental knowledge to get insights into their preferences about different aspects of the eco-feedback interface. Secondly, based on the survey findings, 20 community members from diverse backgrounds worked collaboratively to develop interface design proposals. Finally, the design of the eco-feedback interface was finalised based on the community interface prototypes and suggestions. Overall, this project sheds new light on the opportunities of utilising co-design principles to build eco-feedback interfaces, with interactions between community members during the design stages allowing for the generation of innovative ideas moving the interface beyond feedback and leading to greater adoption and energy savings.
