Thermography

Energy Audit – Thermography

The use of thermography is rapidly increasing as an integral means to inspect building envelopes, roofs, automated controls, building insulation, electrical distribution systems and moisture intrusion. Electrical systems have normal thermal signatures and abnormalities are easily detected as they produce heat through electrical resistance. The procedure is non-invasive; therefore, thermal imaging provides the safest means to troubleshoot high voltage systems. Thermal imaging of process control motors, piping, thermal insulation, actuators and valves can detect wear and the need to plan for repair/replacement before it becomes an emergency. Measuring liquid and gaseous levels in silos and tanks is a common use of thermography to confirm the accuracy of a tank measuring instrument or to calibrate tank monitoring systems. The use of thermography in commercial roof inspections is almost instrumental in a comprehensive inspection. Thermal imaging will show moisture intrusion and allow for its proper repair before the condition affects other components of the building. Thermography is ideal for determining insulation presence and performance as well as locating air leakage and moisture intrusion. The principles and benefits of thermography work on existing as well as new buildings. Ideally, new construction would be imaged for conformance to the building specifications and to develop a baseline signature for future comparison.
