Infrared Thermography is a space age military application that has been successfully applied to energy analysis work. Hand-held cameras similar to digital cameras and camcorders can detect and record small variations in temperatures.
When properly used by skilled professionals, IR Thermography can detect missing insulation, air leaks, wet insulation, electrical hazards, pending equipment failures (heat build-up), and a wide variety of other non-energy related functions that involve temperature variations.
The operation of IR Thermography equipment depends on the application. If used to check building envelopes for insulation integrity, the best time is on a cold, calm night, long after the influences of the sunshine have faded. To check for hot spots during the cooling season, work inside the facility. Equipment hot-spots or water damage can be checked pretty much any time.
Thermography equipment is extremely sensitive to small differences in temperature. The equipment must be used correctly and ethically to produce reliable results.
