Which method can stabilize baseline pressure measurements?

The choice of adjusting the time average feature on a manometer is significant in stabilizing baseline pressure measurements. This method allows for a more accurate representation of pressure changes in the building by filtering out short-term fluctuations and noise. By averaging the pressure readings over a specified period, the influence of transient events, like brief air movement or minor disturbances, is minimized. This results in a steadier and more reliable baseline, which is crucial for evaluating the building’s performance.

In contrast, increasing ventilation may introduce additional variables that can affect pressure readings, making it less useful for stabilization purposes. Closing all windows would certainly impact ventilation rates, but it does not directly stabilize pressure measurements; rather, it may create a more sealed environment that could alter pressure dynamics unexpectedly. Checking for air leaks is essential for overall air sealing and energy efficiency, but it does not specifically address the stabilization of baseline pressure readings, as the presence of leaks can contribute to pressure variability rather than stabilize it.
