Blower Door / Envelope Testing Certification
Residential Properties in Florida Permitted after July 1, 2017 Require Testing
When the Florida Building Code, Energy Conservation Version 5 adopted mandatory air infiltration testing (ie, blower door testing) for new construction homes and residential units, enforcement authorities sought greater clarification on who qualified as an “approved entity” to do the testing.
Sections R402.4.1.2 and R104.5 indicate that a Florida blower door test must be done by an approved third party Energy Auditor or Energy Rater. Both titles require certification – either from the Building Performance Institute (BPI) or Residential Energy Services Network (RESNET) – to qualify.
