This beautiful house in New Windsor, MD went through one of it's final steps to pass code in the state of Maryland. The blower door test, or air leakage test was performed in accordance with the International Energy Conservation Code (IECC). The air leakage code requires that a house test at equal to or less than three air changes per hour (3ACH). The test was conducted using the ASTM E1827 - single point method. The blower door test was conducted five times and each measurement was recorded and entered into the report. Each test result yielded an ACH number less than two so the house passed with flying colors. In Carroll County as well as Maryland, it is important to consider the building envelope so that your house can also pass the test. Tighter houses use less energy and are more comfortable.
