This paper will discuss the limitations of utilizing thermal imaging as a building diagnostic tool, the appropriate and separate methodologies that should be employed for heat, air and moisture deficiencies, the various standards and protocols should be followed, and the complementary quantitative and verification tools that should be used in conjunction with thermography. This paper will try to be as subjective as possible by referencing Canadian and International standards related to building inspections using thermography. This includes historical, current and in-progress standards from National Master Specifications of Canada, ASTM, RESNET and ISO.
