What is the impact of wind on CAZ pressure measurements?

Wind can have significant effects on pressure measurements in Controlled Atmosphere Zones (CAZ) within buildings. When wind interacts with the building exterior, it can create variations in the pressure experienced within the CAZ. These fluctuations occur because as wind flows over and around buildings, it may cause changes in the pressure distribution across the building's surfaces, leading to changes in how air is moved both into and out of the CAZ.

These imbalances can result in either an increase or a decrease in pressure depending on the wind direction and speed. For instance, strong winds may create positive pressure on one side of the building while causing negative pressure on the opposite side, affecting the overall equilibrium of air within the CAZ. Hence, it's essential for buildings to account for these wind-induced pressure changes, especially in design and performance assessments of energy efficiency and indoor air quality.

While the other options suggest various states of pressure consistency or stability, they do not accurately reflect the dynamic nature of pressure changes driven by wind. Wind inherently introduces variability, making it crucial to consider in any analysis involving CAZ pressure measurements.
