Domestic energy consumption is increasing in the UK’s housing stock in the face of government commitments to reduce CO2. Occupant behaviour has been targeted as a promising area in which to effect a reduction in consumption levels but has proved resilient to high level intervention approaches. This short paper explores the constituent elements of energy consuming behaviour and habits and puts forward a conceptual framework to guide future design intervention. Central to this is the implementation of Design for Sustainable Behaviour methodologies to change the nature of occupant-appliance interaction. The paper concludes with a discussion of the role of Digital Media as an agent for such behavioural change.
