Which method is often used to report the air leakage rate in single-point testing?

• A. The average of all measurements
• B. The highest measurement
• C. Only the lowest measurement
• D. The median of all measurements

Answer: (A)

In single-point testing for air leakage rate, reporting the air leakage rate as the average of all measurements provides a more balanced and representative value of the overall performance of a building’s airtightness. This method allows for the consideration of variability and fluctuations in measurements that may occur during testing. Using the average helps smooth out any outlier readings and gives a single value that reflects the general state of the building’s airtightness. It captures the cumulative performance over the series of tests, making it a more reliable indicator of the overall air leakage compared to relying on extreme values such as the highest or lowest measurements, which may not accurately reflect the typical conditions. Therefore, calculating the average is the preferred approach in this context as it emphasizes a comprehensive view of the building’s leakage performance, rather than focusing on isolated data points.
