A diagnostic procedure that measures the airtightness of a building by assessing air leakage rates.
Involves mounting a fan in a doorway to create a pressure difference and identify leaks.
Helps improve indoor comfort and reduces energy costs by pinpointing areas of infiltration.
- - Purpose - Measures building airtightness to identify air leakage points.
- - Procedure - Uses a fan to pressurize or depressurize the building and monitor pressure differences.
- - Preparation - Ensure all windows and doors are closed, and all exhaust fans are turned off before testing.
- - Results - Provides a numerical value indicating the rate of air leakage, often in ACH50 units.
- - Benefits - Helps improve energy efficiency and indoor air quality by locating leaks.
Blower Door Test work typically involves measuring a building's air tightness by creating a controlled pressure difference using a specialized fan installed in an exterior doorway, which allows technicians to assess the rate of air leakage through the building envelope. The process includes sealing the building, setting up the equipment, and conducting measurements while monitoring airflow and pressure data to identify areas of air infiltration or exfiltration. When evaluating requests for blower door testing, key details such as the size and type of the building, its construction age, existing ventilation systems, and specific concerns about air leakage are important, as they help determine the scope of work, required equipment, and any additional diagnostic procedures needed to accurately assess the building's air tightness.
