Measuring air tightness quick and easy

With the A(ir) T(ightness) T(ester) the air tightness of buildings can be measured quick and easy. The ATT makes smart use of the ventilation system. The pressure vessel of the ATT serves as a reference (pressure in the home when the ventilation system is off). While the ventilation system is switched on and off a number of times, the pressure difference compared to the reference is measured. The air tightness (eg the Qv10 or n50) is calculated from this pressure difference and the ventilation air flow. In larger projects with many houses, only a few houses are tested with the blowerdoor. Together with the ATT the air tightness of all houses can be tested in a smooth and accessible way.
