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

Non-financial considerations ≈ financial considerations
• Infrared radiation• Visualise:
– heat loss – missing insulation– draughts– damp– cold bridges
Attention to heat loss Favourable attitudes to
thermal efficiency measuresWhat is the impact of thermal images on householder intentions to install thermal efficiency measures?
Context Thermal Images Method
Thermal Images
Method: Experimental design & interviews
Context Thermal Images Method
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 money unlikely │ -2 │ -1 │ 0 │ 1 │ 2 │likely
enhance my homes appearance unlikely │ -2 │ -1 │ 0 │ 1 │ 2 │likely
cause disruption unlikely │ -2 │ -1 │ 0 │ 1 │ 2 │likely
