1. ANNUAL COLLOQUIUM 2012 Picturing the invisible: what is the impact of thermal images on householder intentions to install thermal efficiency measures? CHARLIE MORRIS-MARSHAM 2 nd Year PhD Researcher 15 November 2012

2. Context Reasons for probably/ definitely not installing 35% costs too high/ savings too low 15% lack of time/ information 7% hassle / disruption 6% no guarantee of savings 5% reduced saleability 4% changed appearance * Department of Energy & Climate Change, 2013. Green deal and ECO data release - October 2013. ** GfK NOP, 2013. Green Deal Assessment Survey: Data tables. 37% ContextThermal ImagesMethod  Non-financial considerations ≈ financial considerations

3. Infrared radiation Visualise: – heat loss – missing insulation – draughts – damp – cold bridges  Attention to heat loss  Favourable attitudes to thermal efficiency measures What is the impact of thermal images on householder intentions to install thermal efficiency measures? ContextThermal ImagesMethod Thermal Images

4. Method: Experimental design & interviews ContextThermal ImagesMethod Aim: Does being exposed to thermal images cause a change in attitudes/ intentions to install measures? Experimental design Anticipated impact: Home assessment process improved to strengthen intentions to install Build theory around non- financial barriers Example question: Installing external wall insulation would* make my home warmer unlikely │ -2 │ -1 │ 0 │ 1 │ 2 │likely save moneyunlikely │ -2 │ -1 │ 0 │ 1 │ 2 │likely enhance my homes appearanceunlikely │ -2 │ -1 │ 0 │ 1 │ 2 │likely cause disruption unlikely │ -2 │ -1 │ 0 │ 1 │ 2 │likely Thank You
