Applications of Infrared Thermography in Locating and Identifying Building Faults
Infrared thermography is a technique that measures the thermal radiation given off by a surface. An important application of this technique is the examination of buildings in order to detect building faults. An outline of the theory of infrared temperature measurement is presented and discussed with reference to the AGA 680 Thermovision System. The environmental conditions that affect a thermographic survey are also outlined. Several common types of building fault which can be detected using thermography are discussed and illustrated. Three case histories of its use in detecting building faults are also given: a problem with a cavity wall, a problem with a high-rise building that was being used as an art gallery, and another examining heat loss from a heritage building.
