The use of thermography for the detection of external finishes defects of buildings in Hong Kong

Abstract

Infrared thermography is said to be a technique that can detect external finishes defects. However, there exist numerous parameters that can affect the accuracy of this technique. Its use should be subject to strict control and the results cannot be considered as conclusive. This paper discusses the complications of the thermal signature and the possible procedures when carrying out the survey. It also indicates that such a technique may be useful to the building control authority for mass‐screening of a large batch of buildings to justify the issuance of statutory orders.
