When PCA is used for IRT, findings can be obtained from the differences between multiple IR images on the same object (wall, building, window, or small region of concern). It has been used to find moisture in envelope, air leakage, defects, and other diagnostics of building envelope systems, and systems inside buildings such as HVAC.
