Thermography is often used to locate leaks in connection with an airtightness check. In this context it is important to know under what conditions the inspection system can recognise defects to a degree of certainty and reproducibility.Applications of leak location in checking airtightness use the excitation of the building envelope, in that energy is drawn through the building envelope at defective points, cooling the building down. In this respect, applications of active thermography would be appropriate. Readings are taken, however, according to the procedures of passive thermography.The evaluation procedures of active thermography will, in what follows, be transferred to leak location applications.
