What are ventilation openings used for in a building?

Ventilation openings are crucial components in a building's design, specifically intended to facilitate air exchange. These openings allow fresh air to enter and stale air to exit, promoting a healthier indoor environment. Proper ventilation is essential for controlling temperature, humidity, and air quality within a space.

By enabling the movement of air, ventilation openings help to disperse indoor pollutants, reduce moisture buildup, and prevent the occurrence of conditions that could lead to mold growth or other health-related issues. This air exchange is vital for ensuring occupants are comfortable and that the building complies with health and safety standards.

While other options may seem relevant, they do not address the primary function of ventilation in the context of building design and air quality management.
