The document discusses a research project called Gooddee2ds that explored a participatory approach to developing a web application to help building users reduce energy consumption. A user group consisting of lay and expert building users from Leicester City Council provided input over 18 months. Findings showed that the user group approach helped foster knowledge sharing and relationships. However, attitudes towards smartphone and social media use varied depending on job roles and needs. The recommendations emphasize tailoring solutions to different user contexts and ensuring trust and security.
