What is Thermography?
SLIDE 4
What is Thermography?
The use of an infra-red camera to measure the thermal radiation emitted by a surface within a select band of wavelengths. The image colour scale can be converted into a temperature by image scanning. Used extensively in medical diagnosis, electrical safety and plant/machinery fault finding.

What is Thermography?
In the built environment, it is a growing field of expertise globally and in its infancy in Australia.

World Examples
SLIDE 7
London
London was the first world City to be thermally mapped in 2006. Buckingham Palace made the news as one of London’s worst hot spots. Other UK cities have followed (Birmingham, Newcastle, Aberdeen and others)
SLIDE 8
Paris
Over 500 significant buildings thermally surveyed in 2009 in advance of the Copenhagen Climate Change Conference.
SLIDE 9
USA
Boston – every building to be thermally surveyed over the next 12-24 months (facades and aerial). Oklahoma – strategic thermal survey of major public buildings under way. Boston Oklahoma
SLIDE 10
Midlothian (UK)
Over 1700 houses surveyed. Envision scanning software and R value algorithm used to detect insulation deficiencies, predict results and savings in energy, emissions and costs. 800 houses insulated – annual emissions reduction over 1.4 million kilos of carbon. The genesis of the SA Building Innovation Fund project.
