Air Leakage and Ventilation Testing

Low-pressure pulse test is the technique developed by the University of Nottingham and Build Test Solutions. It generates an instant pressure rise in the building and pressure decay is monitored and used to determine the building air leakage. This is the method Pulse uses. Quasi-steady is an assumption of steady-state.

What Is An Air Tightness Test And Do I Need One?

Qualified air testers ( ATTMA, IATS, or UKAS-registered) use blower door or pulse testing equipment to pressurise or depressurise a building. External openings are used to measure pressure differentials, air leakage pathways, and temperatures. The test calculates the air leakage and determines compliance with Building Regulations.
