What is typically considered important for obtaining accurate results in air leakage testing?

Obtaining accurate results in air leakage testing is significantly influenced by maintaining consistent pressure settings throughout the testing process. Consistent pressure ensures that the air leakage measurements reflect true performance of the building envelope under controlled conditions, removing variability that might result from fluctuating pressures. Variability could lead to misleading readings, making it much harder to assess the actual airtightness of the building.

Other factors like temperature can affect the density of air and thus impact the results, but focusing on pressure consistency provides a stable baseline for comparison. Relying on analog measurement devices might introduce human error and variability, whereas one-time pressure point readings do not capture the overall dynamics of the air leakage performance, which requires tracking changes in pressure to derive accurate results. Therefore, consistent pressure settings are paramount for the accuracy of the air leakage testing procedure.
