DEFRA’s Seven Population Segments (DEFRA, 2008)
Research about (residential) energy feedback systems tells us • Direct in-home energy feedback systems canmotivate consumer behaviour change, resulting in energy savings ranging up to 20 percent. • Successful feedback has to: • capture the consumer’s attention, • link specific actions to their effects, and • activate various motives. • If this is the case, then different characteristics of the feedback itself become relevant, among them: • frequency, • content, • breakdown, • presentation, • inclusion of comparisons, and • combination with additional information and other instruments. (Darby, 2010; DECC, 2009; Fischer, 2008)

Conclusion • Here is our specification for a ‘best practice’ approach to improving building energy efficiency. It should build from a base of highly effective metering and monitoring tools that will allow: • utility usage profiles to be scrutinised in detail; • learning opportunities (anomalies between predicted and actual impacts as well as ‘cause-effect’) to be identified; • collaborative team-based problem solving to be fostered; • the success of interventions to be measured - holistically; • ongoing performance and repeat behaviours to be monitored and reinforced; and, • a detailed account to be accessible to an audience of interested observers. 14
