Infrared thermography is used extensively in the building construction industry as a quality control and forensic tool to assess air leakage and the presence of moisture in exterior wall assemblies. Infrared thermography applied to large buildings however requires a good building science background and understanding of the dynamic forces which act on the building envelope. This paper shall focus on diagnosing building envelope anomalies in large buildings using infrared thermography and other diagnostic tools.
