If you haven’t yet heard, the results that will be needed in order to pass the House Leakage (Blower Door) test for the 5th Edition Florida Building Code have been modified to 7 ACH50 or less instead of 5. However, if the house tests at 3 ACH50 or less, it will then be required to have mechanical ventilation. These mandatory testing requirements will not go into affect until July 1st, 2017, offering builders a chance to prepare for the change.
Currently, Duct Leakage Testing is only required when following the Prescriptive Path, however many builders throughout the state are choosing to test their duct leakage for the Performance Path as a way to reduce the cost of construction and meet the e-ratio score.
