Building thermography uses the fact that everything above -273oC emits infrared radiation and broadly the hotter it is, the more infrared that is emitted. A thermal imaging camera senses what is happening at a surface, allowing different areas can be compared and conclusions drawn about energy loss.
Diane Hubbard is a qualified thermographer through the Institute of Infrared Thermography and has thermal imaged a broad range of properties, from a castle to cottages. Not only is a thermographic survey effective for identifying energy loss, it can also be used for more specific problems such as roof leaks and poorly performing underfloor heating circuits.
