What is the impact of a windy climate on building ventilation?

In a windy climate, natural ventilation can be significantly increased due to the movement of air across the building. Wind creates differences in air pressure, which can help facilitate the flow of fresh air into and stale air out of a structure. This phenomenon is known as "wind-driven ventilation," where the wind pressure forces air through openings like windows, doors, and vents, improving indoor air quality and helping to dissipate heat.

When winds are channeled into openings, they can enhance airflow throughout a space, allowing buildings to have more effective passive ventilation systems. Therefore, in this context, the windy conditions serve to augment the natural forces at play, promoting a more effective exchange of air within the building.

The other options do not accurately reflect the dynamics introduced by wind. For example, windy conditions typically do not reduce natural ventilation; rather, they bolster it. While there might be situations where additional mechanical ventilation is warranted in windy climates, this is not the primary impact of wind on ventilation. Insulation, although crucial for energy efficiency, is not directly affected by wind in the context of ventilation; rather, it serves to manage energy loss when openings are used for air exchange.
