Summative behaviour change evaluation of up-to-date metered energy feedback in European public buildings

Energy consumption practices and behaviour are increasingly an important focus of attention, for energy efficiency measures. Such is the demand caused by behaviour at the level of the individual, it may cancel out the benefits of engineering solutions, such as more energy efficient appliances (Adua, 2010). This paper focuses on an evaluation of the SMARTSPACES project and its effect on energy-related behaviour change. The project provided two services: an energy management service (EMS) and an energy decision support service (EDSS). These services were implemented in over 450 public buildings across 11 European cities in 8 European countries (Serbia, France, Germany, Italy, The Netherlands, Spain, Turkey and United Kingdom). Building professionals (energy managers) primarily used the EMS and building staff used the EDSS. These services intended to inform, support and enable target audiences to use up-todate metered feedback to reduce energy use in public buildings. The theory of change that underpins the evaluation framework is based in the Elaboration Likelihood Model which aims to understand how communication can influence attitudes and the Theory of Planned Behaviour that examines which attitudes are more likely to predict intentions and behaviours (Wilson, 2014). The paper presents results of ex-ante and ex-post surveys to building staff about their levels of awareness, attitudes, perceived control behaviour and intentions in three selected cities: Bristol, Leicester and Venlo. Outcomes varied across the examined cities depending upon the type of information presented, the level of engagement of users with the energy saving campaigns and the amount of previous energy management work undertaken by buildings’ facilities and energy management professionals.
