TY - JOUR A1 - Lorek, Sylvia A1 - Spangenberg, Joachim T1 - Energy sufficiency through social innovation in housing JF - Energy Policy N2 - Experience shows that energy savings through energy efficiency measures are partly compensated by income growth, and partly by rebound effects. Therefore to be effective, efficiency measures have to be embedded in a concept of sufficiency which strives for limits and absolute reduction of energy consumption. While the sufficiency concept is not new, it only recently gained attention in the field of housing. This paper provides a basis for broader and more informed debates in policy and research on the potential of sufficiency considerations to contribute to the overall reduction of energy consumption in the residential sector. It recommends shifting the attention from energy consumption of buildings towards a concept of sustainable homes in which e.g. the size of the living area plays a crucial role. A further important aspect is the possibility to fulfil other basic needs like the provision with food, recreation and social contacts in the nearby environment. The paper describes first examples of housing projects guided by sufficiency criteria, depicts the potential roles of different actor groups and points towards some general policy recommendations.

The Theory of Planned Behaviour TPB and Social Practice Theory SPT offer different views on consumer behaviour, and on ways to change it. This paper briefly describes the challenges, discusses the applicability of both theories and their meaningfulness for policy recommendations. We suggest an approach combining results of both bodies of theory, complemented by ideas from political economy, to substantiate the Prism of Sustainable Consumption we introduce as a heuristic sufficiency policy tool. It is useful to identify affordability criteria for change in each dimension, as the basis for deriving suggestions for effective policy interventions. We conclude that (i) effective interventions are possible, (ii) they have to address several dimensions of affordability simultaneously, and (iii) the sufficiency policy space prism can be a useful tool in structuring planned interventions.
