How Often Should Airtightness Testing Be Performed? What Are Common Causes of Air Leaks? Can Airtightness Testing Improve Energy Efficiency? What Equipment Is Used for Blower Door Testing? How Does Climate Affect Airtightness Testing Results?
Air tightness testing, also known as air leakage testing or blower door testing, involves the quantification of the uncontrolled airflow through the building envelope. It aims to identify areas of air leakage, typically at joints, gaps, and penetrations in the building structure.
Airtightness Testing 101. An airtightness test is a whole building test that measures how easy it is for air to leak through a building's enclosure or skin. One common method is to use a large fan or blower to extract air from or supply air to the building (see Figure 1). This fan is inserted...
Air tightness testing allows inspectors to identify leakage points so they can be sealed before the HVAC system is fine-tuned. This ensures that ventilation is properly controlled and indoor air quality is maintained without wasting energy.
