The air leakage test plays a crucial role in energy auditing by measuring the air tightness of a building. This test is essential for understanding how much outside air leaks into a structure and how much conditioned air escapes. High levels of air leakage can lead to increased energy costs and reduced indoor comfort, as well as affect the overall energy efficiency of a building.

By determining the extent of air leakage, energy auditors can recommend improvements such as sealing gaps, adding insulation, and enhancing weatherization. These measures contribute to better energy performance, lower utility bills, and improved HVAC efficiency. The results from the air leakage test guide homeowners and building managers in making informed decisions about energy-saving upgrades, ultimately leading to a more comfortable and sustainable living or working environment.
