Does a thermal imaging camera really show energy losses?
4) A thermal imaging camera is a valuable tool in analyzing heat flows in a building. The camera is not sensitive to visible light, but only to temperature. If it is cold outside an image of poor insulation in a wall will show cold (blue) compared to normally insulated areas. Commonly the building space is pressurised using a Blower Door fan system during testing so that air leaks will show in images where the cold air is leaking to the indoors space. These images then allow educated decisions on energy conservation measures such as space sealing, insulation retrofit and other building modifications.
