  3. Background to the project Huge difficulties in achieving energy efficiency uptake “It is difficult to explain low take up of energy efficiency as purely a rational response to investment under uncertainty” (Stern 2007) Many failed attempts to explain/predict from single discipline perspectives Energy Cultures – interdisciplinary / systems approach

  4. The Energy Cultures framework

  5. House characteristics Insulation Energy sources Heating devices habit Number of rooms heated Social aspirations Expected comfort levels Heat settings Hours of heating Environmental concern Maintenance of technologies Respect for tradition


  7. Choice modelling

  8. Household surveys


  10. Involvement of whole team Problem definition Research design Values – “laddering” Choice modelling Research stages led by single disciplines Findings discussed by whole team Household surveys Legal & policy analysis Focus groups 2009-11 Social network analysis Involvement of whole team Analysis & integrate findings as a whole 2011-12 Involvement of whole team 2012 Design & test interventions

  11. A few research highlights

  12. Household Surveys Two national on-line surveys in parallel • National sample of 2400 + 800 from case study areas • Household energy survey – detailed information on house structure, technologies, practices, beliefs, influences on change Loads of data, analysis ongoing • Choice modelling - preferences for space and hot water heating

  13. Some results: Space Heating • Living area nearly always heated but rest of house much less often. • 40% can set temperature control in living room – usually 20-22° but ranges from 15 to 30° • Main heating types are electric heaters, heat pumps and woodburnersBUT 20% still use portable gas heaters

  14. Some Results: Appliances: Have and use Have and don’t use Dehumidifiers 32% 11% Dishwashers 50% 7% Clothes driers 51% 13% Plasma TV 24% LCD/LED TV 49% Heated towel rails 29% 18% 75% washing machines are cold fill 70% claim energy efficient light bulbs as standard

  15. Some results: Energy Behaviours • 12% changed heating method in previous 12 months • 16% changed some aspect of insulation in previous 12 months • 30% keep heating low to save money • 21% say they have gone without heating because they couldn’t pay a bill. • 9% need extra power for health reasons • We estimate 18% are in energy poverty (more than 10% of household income on energy)

  16. Energy ‘cultures’ – from household surveys

  17. Two-step cluster analysis

  18. Cluster 1 (21%) • Lower income (more < $20,000, few >$80,000) • Younger (many 20-30) • Many not in employment, students • Older houses, smaller houses • Many rent – private, HNZ, council • More portable electric heaters, gas heaters(?) • Few appliances - no dishwasher, separate freezer, clothes drier • Do many energy saving practices: Switch off at wall, Reduce heating unoccupied rooms, Switch off lights, Keep heating low, Line dry laundry, Shorter showers, Reduce water temp, Dishes by hand • Less likely to have energy efficient technologies, saving lights, energy efficient heating, double glazing • No ceiling, wall, underfloor insulation, don’t seal drafts • Believe energy choices aren’t complex; we should stop exploitation of resources • Lowest winter electricity bill

  19. Cluster 2 (40%) • All incomes – but many $20-30000 • More aged 55 plus • Many retired • Tend to own debt free • Regions – Taranaki, Tasman, Hawkes Bay • Mixed practices: Have & use dehumidifiers, separate freezers, towel rails. Have & don’t use clothes driers, dishwashers • Have many energy efficient technologies: ceiling, wall, underfloor insulation, seal drafts • Heat pumps, central heating • Often talk to friends re energy • Pleasure less important • Support minimum standards on appliances + labelling

  20. Cluster 3 (39%) • Over $70,000 pa • Age 20-50 • In full time work, including self employed • Own with a mortgage • Bigger houses, 4-5 bedrooms • Many heat systems coal, wood, gas, heat transfer systems, some not used • Instant electric and gas water heating • Lots of appliances: Dehumidifiers, clothes driers, plasma TVs, games consoles, laptops, Tubular TVs, video recorders, computers, spa pools • Do few energy saving practices: Rarely reduce heating in unoccupied rooms; Don’t keep heating low; Less likely to switch off lights; Less likely line dry laundry; Less likely shorter showers; Less likely dishes by hand • Think energy choices are complex • Protecting environment not important • Overall spend most on most forms of energy

  21. Policy intervention conclusions • Cluster one – doing practices, material culture lacking – therefore target landlords including Housing NZ • Cluster 2 – already engaged – asking for customised information and performance standards • Cluster 3 - Not engaged and least concerned – regulation re housing, appliances or pricing??

  22. Energy ‘cultures’ – from Choice modelling

  23. Choice modelling findings • 1000Minds • Respondent-specific estimates of relative utility of various attributes of space heating and water heating systems • Then used cluster analysis to determine plausible groups (‘cultures’)

  24. Cluster 1 – 16% water heating, 14% space heating Most concerned about upfront costs Policy implications for this cluster: • Subsidies necessary, but not sufficient for some • Low- or no-interest loans?

  25. Cluster 2 – 17% space heating Willing to invest in more expensive heating but concerned about recovering costs on sale of house Policy implications for this cluster: • Home energy audits and home certification programme

  26. Cluster 3 – 23% water heating, 21% space heating Most concerned about functional reliability of technologies Policy implications for this cluster: • Independent testing and certification needed

  27. Cluster 4 – 35% water heating, 22% space heating Main concern is aesthetics (fit with house, impact on neighbours) Policy implications for this cluster: • Opportunities for designers & installers • Subsidies may need to be more flexible

  28. Cluster 5 – 26% both groups Preference for some independence from the grid for space and water heating (e.g. solar hw, wetbacks, solid fuel fires etc) Policy implications for this cluster: • May respond well to subsidies or loans for solar hot water • Is there a wider appetite for off-grid; if so, does this extend to desire for feed-in to grid?

  30. End of Year 2 • All investigative research stages completed ... although new avenues opening up! • Ongoing interest & engagement with key stakeholders • Significant international interest & desire to collaborate or emulate • Year 3 (project ends Sept 2012) • Papers & conference presentations ongoing • Intervention study with DCC, drawing from findings about change motivators Current state of play
