Description

Infrared thermography is a process that uses an infrared scanner to produce thermal images of surfaces by detecting the radiosity of these surfaces. The use of infrared thermography (IR) as a diagnostic tool in building science has been known particularly for qualitative assessment of building envelopes. Its use as a quantitative means to measure surface temperatures was demonstrated in a major Canada/USA joint research project that used IR thermographic techniques to measure the surface temperature of insulated glass window units. The results of that project were published in 1996. The earlier work has now been extended in a recent study of complete window assemblies (including frames).

This paper describes the use of IR thermography to determine surface temperatures of the glass and frame members of two window units and a calibration transfer standard unit. The IR results were compared with thermocouple temperature measurements at specific locations on the surface of the assemblies. Other participants in this project have presented their findings in ASHRAE publications, and a summary paper will be prepared to compare all the experimental and simulation results. This paper focuses on the results obtained from the work performed at the Institute for Research in Construction of the National Research Council Canada (IRC/NRCC).
