Lufttæthedsprøvninger
Lufttæthedsprøvninger, also known as airtightness testing or blower door testing, are crucial procedures used to measure the air leakage rate in buildings. This process quantifies how much uncontrolled air enters or leaves a building through cracks, gaps, and openings in the building envelope. The primary tool used is a blower door, which consists of a powerful fan mounted in an exterior doorway. This fan is used to either pressurize or depressurize the building, creating a controlled airflow.
During a lufttæthedsprøvning, the fan speed is adjusted to achieve a specific pressure difference between the
The results of a lufttæthedsprøvning are vital for several reasons. They help identify areas where heat loss
