A diagnostic method to measure a building's air tightness by identifying air leaks and infiltration points.
Ensures improved indoor comfort and reduces energy costs by minimizing unwanted air exchange.
Involves closing all windows and doors, and turning off HVAC systems to obtain accurate blower door readings.
- - Preparation - Ensure all windows and doors are closed, and exterior vents are sealed before testing.
- - Equipment - Use a calibrated blower door fan to measure air leakage accurately.
- - Testing Procedure - Conduct depressurization and pressurization tests to identify leakage points.
- - Data Collection - Record pressure differences and airflow rates for analysis.
- - Reporting - Provide a detailed leakage report to guide necessary sealing or repairs.
Blower door testing involves using specialized equipment to measure the airtightness of a building by creating a pressure difference and assessing the rate of air leakage through the building's envelope. The process typically includes setting up a fan in a doorway, sealing all other openings, and then recording the airflow required to maintain a specific pressure difference. When evaluating requests for blower door testing, important details include the size and type of the building, its construction materials, existing ventilation systems, and any previous air leakage assessments. These factors help determine the scope of the test, required equipment, and the potential need for follow-up repairs or modifications.
