Diagnosing Air Leaks in Building Enclosures

Wednesday May 8, 1:00pm – 2:00pm

Grand Ballroom

The need for new construction airtightness has been growing for decades, but has been booming in the last 10 years specifically. While airtightness testing is required in some jurisdictions by energy codes, other projects may have a specification requirement or an energy program requirement. In these cases, a whole-building, or partial-building test will occur.

When airtightness testing results in a failing grade, diagnostic testing is typically performed to locate the breaches so they can be repaired. This presentation will help identify how these diagnostic tests are performed along with their pros and cons.

Learning Objectives:

  1. Learn common test methods used for locating air leaks in building enclosures
  2. Apply the most appropriate diagnostic techniques to specific
  3. Adjust testing techniques for environmental conditions
  4. Analyze the test results
