Requirements for Testing in Residences
There are specific regulations for residences to pass the Blower Door test that should be taken into consideration beforehand.
In many US states like Florida, a Blower Door Test must be performed on all homes. All residential constructions in Florida permitted as of July 1st, 2017 must have this vital testing process done successfully.
Those homes permitted after July 1st, 2017 need to do the blower door testing, according to the 5th edition of Florida Building Codes Air Change Per Hour (ACH) which requires less than seven air change per hour, and the tester must be approved by a third-party agency.
It is important to mention that the Blower door test mustn’t be done by a party who was involved in the construction or design process of the home.
The residential units included in the code are single homes, townhomes, and duplexes. But for multifamily buildings under three stories, testing is required for each individual unit.
To complete the test, the Blower Door Test Form must be filled out as well. After that, a passed and completed BTDF copy will be left on the wall adjacent to the electrical panel for the inspector to look over at the final building inspection. Other copy will be sent to the construction manager via email.
If the ACH (air changes per hour) is less then three, then mechanical ventilation must be installed. This adjustment must have approved plans on how the ventilation will be provided and confirmed by the third party that has performed the blower door testing.
