Institutional, social and individual behavioural effects of energy feedback in public buildings across eleven European cities

A summative evaluation was conducted to understand impacts of different information provision in these cities. Qualitative data were gathered through a set of interviews with 40 building professionals at the central or building level. These interviews identified differences in how the energy efficiency communication-based campaigns were implemented at each site and elicited factors to explain how users' perceptions and understanding changed as a result of the interventions. The evaluation framework helped to identify not only improvements in the delivery of communication-based campaigns, but also the communication factors that impacted on individual behaviour change. The research highlighted the influence of institutional and social effects on individual beliefs and norms. To achieve more effective change in attitudes to reduce use, energy feedback needs to be supported with engagement activities, such as energy coaches, campaigns, and interactive online fora.
