In 2012, the International Energy Conservation Code (IECC) started requiring residential construction pass an air leakage–rate test, better known as a blower-door test. My area of the country mandates test results at or below three air changes per hour at the test pressure of 50 pascals (3 ACH50). In warmer climates, 5 ACH50 is typical.
