To test levels of air tightness and locate leaks in a home, a large calibrated fan called a blower door is used to evacuate air from the interior. This fan depressurizes the building down to -50 pascals, which is the equivalent of a 25 mph wind hitting the house from all directions at once. Under this pressure differential, any areas contributing to leakage can be found and remedied.
