Blower Door Test-Out

The test-out phase of the weatherization project is important for three reasons. First, it verifies that the weatherization crew has sufficiently completed their tasks; second, it documents pre- and post-weatherization airtightness; and finally, it shows the occupants how the weatherization work has improved their home's energy efficiency.

After completing this lesson, auditors will be able to:

  • Explain why it is important to verify the results of the weatherization work
  • Carefully document post-weatherization airtightness measurements
  • Verify the improvements to the home with the occupants and conduct the exit interview
