Pulse Testing

Understanding Pulse Testing

Pulse testing is a relatively new and innovative method for measuring air leakage in buildings. Unlike the traditional blower door technique, it doesn’t require creating a significant pressure difference across the building envelope. Instead, it utilises a quick burst (or “pulse”) of air released into the building and analyses the pressure decay over a short period. By measuring this decay, the test provides data on the building’s overall airtightness.

Applications of Pulse Testing

Pulse testing is suitable for various situations:

Advantages and Limitations of Pulse Testing

Pulse testing has some benefits:

However, it also has limitations:

Blower Door Testing

Understanding Blower Door Testing

Blower door testing is the traditional and most widely recognised method for measuring building airtightness. It involves installing a powerful fan into a doorway, creating a pressure difference between the inside and outside of the building. By measuring the airflow required to maintain this pressure difference, the test determines the building’s air leakage rate.

Quick Comparison of Pulse Testing and Blower Door Testing

Both testing methods serve the same purpose of evaluating building airtightness, but they differ significantly in their approach. Here’s a quick comparison:

Conclusion and Considerations

Choosing between pulse testing and blower door testing depends on your specific needs and priorities. Here are some key considerations:

It’s important to consult with a qualified building performance professional who can assess your specific situation and recommend the most appropriate testing method for your needs. In some cases, a combination of pulse testing and blower door testing might be beneficial, providing a more comprehensive picture of the building’s airtightness.

By understanding the differences between pulse testing and blower door testing, you can make informed decisions to ensure your building achieves optimal energy efficiency, occupant comfort, and indoor air quality.
