Which building condition is most likely to create a misleading thermal anomaly due to reflected infrared radiation?

Which building condition is most likely to create a misleading thermal anomaly due to reflected infrared radiation? A) Wet insulation B) Shiny metal ductwork C) Air leakage through framing D) Missing insulation Correct Answer: B) Shiny metal ductwork Infrared thermography is widely used in building diagnostics, energy audits and condition monitoring to detect temperature variations on surfaces. Thermal cameras detect infrared radiation emitted by objects, which allows inspectors to visualize temperature differences. However, thermography does not always measure true temperature. In some cases, it measures reflected infrared radiation, which can create misleading thermal anomalies. One of the most common sources of this error in buildings is shiny metal surfaces such as metal ductwork. Understanding Reflected Infrared Radiation In thermography, three types of radiation affect the camera reading: Emitted Radiation – Infrared energy emitted by the object itself. Reflected Radiation – Infrared energ…
