Abstract: Infrared thermography is a modern non-destructive measuring method for the examination of redeveloped and non-renovated buildings. Infrared cameras provide a means for temperature measurement in building constructions from inside and outside as well. It has been shown that infrared thermography is applicable for insulation inspection, identifying air leakage and heat losses sources, finding the exact position of heating tubes or for discovering the reasons why mould, moisture is growing in an area and it is also used in conservation field to detect hidden characteristics or degradations of building structures. Infrared thermography is equipment or method, which detects infrared energy emitted from an object, converts it to temperature, and displays image of temperature distribution. In Construction Industries, the application of infrared thermography is not limited to passive investigations but active investigation too. Some defects like voids in concrete or masonry, delaminations at interfaces of an object which have a different density or heat conductivity can also be detected and characterised. Infrared thermography, due to its non-contact character that allows for quick 2D surface mapping, represents a powerful tool for non-destructive testing (NDT) of materials and structures. As Infrared thermography is still not completely exploited and traditional methods are still employed. Due to the ambiguity in the analysis by using traditional methods of non-destructive testing this method emerges as an easy and quick method. So, in this paper, different areas are taken for inspection on the campus of Veermata Jijabai Technological Institute, Matunga, Mumbai, and at the same location traditional methods of NDT are also performed and the results are compared. Thus, temperature measurement must be completed during a short elapsed time after the pulse heating. The infrared thermography is useful in detecting invisible defects non-destructively, extensively and safely.
