  1. Simple, timely and actionable informationimproves commercial office building performance Craig Roussac, Investa Property Group

  2. After initial improvements, rate generally slows Natural Gas 49 percent reduction since 2003/04 Electricity 30 percent reduction since 2003/04 MJ/m2 kWh/m2 Greenhouse Emissions 31 percent reduction since 2003/04 Water 43 percent reduction since 2003/04 kg.CO2/m2 L/m2

  3. Our best buildings follow a similar pattern

  4. Similar buildings, almost identical jobs, different outcomes… ‘Operator-Factor’ seems to be important ~20% reduction ~50% reduction

  6. DEFRA’s Seven Population Segments (DEFRA, 2008)

  7. 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)

  9. A ‘steady state’ base is required for meaningful analysis

  10. Simple email messages on a daily basis

  12. Impact of well-targeted fine-tuning can be profound Building D4NMI Data for Yesterday (Monday 27 August 2012) and its Closest Like Weather Day (Tuesday 10 July 2012) (Source: Investa Sustainability Institute)

  13. Pulse: fuel for a virtuous cycle?

  14. 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
