How does combining thermography with whole building air leakage testing help?

Combining thermography with whole building air leakage testing is beneficial primarily because it can locate hidden air leaks. Thermography uses infrared technology to detect variations in surface temperatures, which can indicate areas of air leakage that are not visible to the naked eye. When integrated with air leakage testing, thermography enhances the ability to pinpoint specific locations where air is escaping or infiltrating, even in concealed areas such as walls or ceilings.

This dual approach provides a more comprehensive view of a building's envelope performance, enabling professionals to identify and address energy efficiency issues more effectively. By finding these hidden leaks, corrective actions can be taken, ultimately contributing to improved building performance and occupant comfort.

The other options focus on cost reduction, speed, and the frequency of inspections, which while relevant to testing strategies, do not capture the distinctive advantage of using thermography in conjunction with air leakage testing. The primary strength of the combination lies in its ability to uncover and address air leaks that might otherwise remain undetected.
