How does a Blower Door System Work?
An apparatus consisting of a calibrated variable speed fan built into an assembly is installed in place of a door. Manometer gauges or digital manometers are also installed to measure pressure differential. Outside air is forced into the property being evaluated creating a positive pressure as compared to outside or the reverse is performed creating a negative pressure. The auditor can use a smoke pencil to locate air leaks.

Data typically collected from Blower Door tests:
  • Air flow at various pressures
  • Air-changes per hour (ACH)
  • Leakage area (ELA)
  • Air flow per area
