Blower door testing is a diagnostic tool that helps to locate air leaks in the building envelope. This test is a necessary part of most green building standards. It can also help you to save money on your energy bill and make your home more environmentally friendly.
Does crawlspace encapsulation cause mold?
In order to pass the blower door test, you must be able to find and fix leaks in your home. There are many places where leaks occur. These include the attic, walls, and the roof. You can identify leaks by using a non-toxic smoke pencil or infrared camera.
Leaks can be small or large, and they affect the amount of heating, cooling, and dehumidification that is needed. To be sure that your home is not a source of leaks, you should perform a comprehensive home energy audit. The cost of the audit usually ranges from $300 to $500.
For a complete energy audit, the auditor will ask you to allow access to every room in your home. They may also ask you to enter the attic, crawlspace, and other areas. Once they have all the information, they will set up the parameters for the test.
After the parameters are set, the energy auditor will begin the test. They will use a non-toxic smoke pencil to draw a white vapor trail.
Once the test is finished, they will observe the home to look for areas where air is flowing back into the house. Their expert will calculate the air infiltration rate of the build.
