During a blower door test the program controls the speed of the blower door fan prompts for installation or removal of flow rings records both building pressure and fan airflow and calculates and stores test results.
So far it seems clear.
Last year we built an energy star home for a customer and we used a blower door test to evaluate the houses air infiltration performance.
This test ensures a certain level of energy performance and is often used when a project team is aiming for a performance based.
For the blower door test it is specified that the test must be undertaken to en13829 method a and that the blower door reference volume called vn50 in the phpp is the full internal air volume of the building under test.
Both techniques use an orifice blower door to induce pressure differences across the building envelope and to measure those pressure differences and the resulting airflows.
Plug up all syphons and exhaust ducts if still without their accessories.

It can also be used to measure airflow between building zones to test ductwork airtightness and to help physically locate air leakage sites in the building envelope.
Internal doors on the other hand need to remain completely open.
