Blower Door Test
Determines Energy Efficiency in your Home.
Reduce air leakage and improve indoor air quality with a blower door test.
There are multiple ways to determine the energy efficiency in a house with a home energy audit including a blower door test. The ventilation in a building's 'envelope' is there to provide fresh air to the inside of a building and to dilute any pollutants in order to improve indoor air quality. The main purpose of performing a blower door test is to measure the tightness of the building envelope and to determine if there are any air leaks. Air leaks can cause the air conditioner or heater to have to work on overtime since cool/hot air is being released out of the building.
Below are a few reasons for establishing the proper
- Reduce energy consumption due to air leaking
- Avoid moisture and condensation issues
- Improve comfort by avoiding uncomfortable drafts coming in through leaks
- Improving indoor air quality by proper air filtration
How blower door tests work
blower door is a powerful fan that mounts to the frame of an exterior
door. The air pressure is reduced in the house by the air that the fan
is pulling outside. The higher air pressure from the outside flows
inside through unsealed cracks and openings. These tests determine the
air infiltration rate of a building. Some blower doors are not
calibrated and can only locate leaks in the building but cannot
determine the overall tightness of a building like a calibrated blower
Once the air leaks have been located in a building,
professionals can improve the tightness of a building and fix the air
leaks. In hot and humid areas like Columbia, SC, air leaks can present a
serious energy efficiency and comfort problem.
