What is an important factor that influences indoor air quality in a building?

Ventilation methods play a crucial role in determining indoor air quality in a building. Effective ventilation is necessary to dilute indoor pollutants, such as carbon dioxide, volatile organic compounds, and other harmful substances, ensuring that fresh outdoor air is brought in to replace stale indoor air. It helps in maintaining a balance of air exchange, which is essential for removing contaminants and managing humidity levels.

Inadequate ventilation can lead to a buildup of unwanted pollutants, which can affect occupants' health and comfort. Proper ventilation strategies can also help regulate temperature and humidity, further contributing to a healthier indoor environment. Therefore, focusing on ventilation methods is critical when discussing factors that influence indoor air quality.
