Air Infiltration Defined

Air infiltration refers to the unintended or uncontrolled flow of air into a building from the outside through leaks, cracks, and openings in the building envelope. This can occur through gaps around doors and windows, electrical outlets, plumbing fixtures, and other openings. Infiltration can lead to higher energy consumption as heating and cooling systems work harder to maintain a comfortable indoor temperature, and it can also impact indoor air quality.

Air Tightness and Ventilation Considerations

To determine the amount of air leakage through infiltration we can carry out air tightness testing. A balance is required between air tightness and ventilation. Air infiltration is relied upon for ventilation strategies, such as a System 1 Intermittent Extraction and Background Ventilation.

Building Compliance Testing

We are a multi-disciplinary consultancy so we fully recognised and understand the relationships between air leakage and the health of a building. Contact us today to discuss your project.
