SUMMARY
Confirm Envelope Performance and Energy Code Compliance
Air infiltration testing measures the amount of outside air that leaks into a building. This testing verifies compliance with the IECC, reduces the number of failed inspections, and helps teams identify envelope issues before closeout.
Most projects require testing per dwelling unit or sleeping unit. Blink Energy also performs whole-building blower door testing for commercial and large multifamily buildings throughout Texas.
WHAT IS AIR INFILTRATION TESTING?
Measuring Air Leakage with Blower Door Testing
Air infiltration testing utilizes a temporary blower door system to assess a building’s air leakage. During the test, a calibrated fan pulls air out of the space and measures how much outside air enters through unintended openings in the building envelope.
In simple terms, the test measures how tightly a building is sealed, or how much outside air is able to enter.
The results provide clear, repeatable data that is recognized by cities, inspectors, and design teams and accepted for permitting and inspections.
WHEN AIR INFILTRATION TESTING IS REQUIRED
Common Triggers for Blower Door Testing
Air infiltration testing is commonly required in the following situations:
HOW THE TEST WORKS
Blower Door Testing Process
Building Setup
- Exterior doors and windows closed
- Interior doors open
- HVAC systems turned off
- Penetrations sealed to their intended final condition
These include:
- Insulation type, thickness, and placement
- Air sealing at penetrations, joints, transitions, and above ceilings
- Window and door performance ratings (U-factor, SHGC)
- Consistency with details shown in plans and compliance paths
Test Procedure
The test results in a clear outcome: Pass or Does Not Meet the Requirement, with measured leakage values documented.
- A blower door fan is installed in an exterior doorway
- The fan depressurizes the building or unit
- Air entering through the envelope is measured
- Results are compared to IECC leakage limits for the applicable building or unit type
WHAT WE MEASURE
Air Leakage Metrics and Observations
During testing, Blink Energy measures and documents:
TESTING FORMATS
Flexible Testing Options for Any Project Type
Per-Unit Testing
Common for multifamily, senior living, assisted living, hospitality, and student housing projects. Each dwelling unit or sleeping room is tested individually.
Unitary/Compartment Testing
Used for tenant spaces or conditioned zones within larger buildings.
Whole-Building Testing
Appropriate for commercial buildings, schools, and large multifamily properties. Whole-building testing requires additional coordination to control access, manage building systems, and maintain envelope conditions during the testing process.
WHY AIR INFILTRATION MATTERS
Why Envelope Tightness Impacts Performance
Blower door testing provides objective data to evaluate envelope performance before small issues become costly problems.
Excessive envelope leakage affects:
Energy use and utility costs
HVAC system sizing and reliability
Occupant comfort and draft control
Humidity and moisture management
Indoor air quality
Inspection outcomes and code compliance

WHAT WE NEED BEFORE TESTING
Preparing for Air Infiltration Testing
If the building is not ready, Blink Energy can perform pre-test evaluations to identify sealing priorities and reduce the risk of failed testing.
To perform testing, we typically need:
