Influence of occupants' behaviour on energy and carbon emission reduction in a higher education building in the UK

This article focuses on one of the case studies in the Carbon Brainprint research project funded by the Higher Education Funding Council for England (Chatterton, J., D. Parsons, J. Nicholls, P. Longhurst, M. Bernon, A. Palmer, F. Brennan, et al. 2015. "Carbon Brainprint - An Estimate of the Intellectual Contribution of Research Institutions to Reducing Greenhouse Gas Emissions." Process Safety and Environmental Protection 96: 74-81). The UK total CO(2)e emissions in 2010 amounted to 582MtCO(2)e. It is estimated that non-domestic buildings and domestic buildings were responsible for 18% (106MtCO(2)e) and 28% (165MtCO(2)e) of these emissions, respectively. A case study method was used to investigative the opportunity of using occupants' awareness and behavioural interventions to reduce energy use and carbon emissions in a non-domestic building of a higher education institution. An action research approach, informed by the theory of planned behaviour, was argued for this case study. It has demonstrated 20% savings in lighting, office equipment and catering energy use, largely through user awareness and behaviour change. If this level of saving were to be reflected throughout the non-domestic building stock it would represent an annual reduction in the order of 7MtCO2e in the UK. These figures relate specifically to non-domestic buildings. However, some of the techniques involved are directly transferable to domestic buildings, with the potential for further emission reductions.
