Blower door testing identifies air leaks in a building's envelope to improve comfort and energy efficiency.
It measures the airtightness of a structure to ensure it meets specified standards and codes.
The test helps evaluate and improve the effectiveness of ventilation systems by detecting unintended air exchanges.
- Purpose - Measures building airtightness to identify air leaks.
- Preparation - Ensure all windows, doors, and vents are properly closed before testing.
- Procedure - A blower door fan is installed in an exterior door to create a pressure difference.
- Results - The test provides a blower door test result, usually in ACH50 or CFM50.
- Applications - Used by inspectors and contractors to improve building envelope performance.
Blower door testing involves measuring the airtightness of a building by using a specialized fan to pressurize or depressurize the space and assess the rate of air leakage through the building envelope. The process typically includes sealing the building, setting up the fan in a doorway, and recording pressure and airflow data to determine the level of infiltration or exfiltration. When evaluating requests for blower door testing work, important details include the size and type of the building, the purpose of the test, the current condition of the structure, and any specific areas of concern or previous issues related to air leakage. These details help determine the scope, equipment requirements, and potential challenges associated with the testing process.
