The blower door test is quite simple. Its operation is based on an airtight door system, which includes a fan between the inside of the building and the outside. The calibrated fan pressurizes and depressurizes the building and simultaneously measures the pressure and the air flow. The measurement is expressed in CFM50 and ACH50. The CFM50 is a unit that refers to the number of cubic feet per minute that the airflow passes through the fan to create a pressure difference of 50 Pascals. Why 50 Pascals? This is the pressure difference from the inside to the outside created by a wind of 32.2 km\/h (20 m\/h) also blowing on outside surfaces. The measurement obtained is converted into ACH50, which is the number of renewals per hour at a pressure of 50 Pascals.<\/p>\n

For completely airtight homes, the measurement obtained is 1.5 or less. An airtight house gets a figure of 1.5 to 3.57 and a building with a medium seal, a figure of 3.57 to 4.55. Finally, a leaky home gets a measure of 4.55 to 10.35. As a general rule, properties with a recent construction date should be airtight.<\/p>\n<\/div>\n<\/div>\n

The blower door test is the way to verify if a building is leaky or air tight. Simple and effective, it identifies areas with air leaks and measures the amount of air entering into a building. The blower door test is therefore essential to prevent air infiltration and energy loss.<\/p>\n
