1 1 these test methods describe two techniques for measuring air leakage rates through a building envelope in buildings that may be configured to a single zone.
This test ensures a certain level of energy performance and is often used when a project team is aiming for a performance based.
Professional energy auditors use blower door tests to help determine a home s airtightness.
The second part of this series will pick up with our blower door test from the moment we turn on the manometer.
A blower door is a machine used to measure the airtightness of buildings.
There are three primary components to a blower door.
These are some reasons for establishing the proper building tightness.
Simply put a blower door is a diagnostic tool used to measure how much air infiltration air leakage occurs in a house.
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.
Blower door tests are performed by trained and certified energy auditors but a homeowner can conduct a mini test to help pinpoint leaky areas of the home.
Plug up all syphons and exhaust ducts if still without their accessories.
Our energy saver 101 infographic explains the importance of a blower door test during a home energy audit.
Internal doors on the other hand need to remain completely open.

Tectite can also be used to analyze manually collected blower door test data.
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.
Understanding blower door test results.

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.
A blower door test is a machine used to calculate airflow between the interior and exterior of a structure measure the airtightness of buildings and identify spots where air is leaking through a building envelope.
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.
