The primary diagnostic procedure for determining the thermal performance of a building envelope is infrared thermography. It can be used to survey and identify heating and cooling loss due to poor construction, missing or inadequate insulation and moisture intrusion. Surveying, identifying and correcting these defects plays a major role in increasing building efficiency and structural integrity.
Thermography can identify surface temperature variations of the building envelope, which is a direct correlation to problems in the structure, thermal bridging, moisture content and air leakage.
