The primary function of ventilation systems in buildings is to provide fresh air and remove stale air. Proper ventilation is essential for maintaining indoor air quality and ensuring a healthy environment for occupants. Fresh air intake helps to dilute indoor pollutants, such as carbon dioxide, volatile organic compounds (VOCs), and other contaminants that may accumulate over time. Additionally, by removing stale air, ventilation systems prevent the air from becoming stagnant, which can lead to discomfort and health issues.

This function is vital in various building types as it supports not only the health and comfort of occupants but also the performance of the building's heating and cooling systems. Inadequate ventilation can result in moisture buildup, which may lead to mold growth and structural damage. Thus, the comprehensive role of ventilation in maintaining air quality and promoting occupant well-being makes it the primary focus of ventilation systems.
