What is the purpose of outdoor air ventilation systems in buildings?

The primary purpose of outdoor air ventilation systems in buildings is to maintain indoor air quality. These systems are designed to introduce fresh outdoor air into the building, which helps dilute and control indoor pollutants, odors, and excess moisture. By replacing stale air with fresh air, ventilation systems support a healthier indoor environment, which is crucial for the well-being of occupants.

Proper ventilation can significantly reduce airborne contaminants, thereby minimizing the risk of respiratory issues and allergies, and ensuring a comfortable living or working space. This aligns with standards and regulations aimed at promoting healthy indoor environments, making the role of outdoor air ventilation essential in building design and operation. The effectiveness of ventilation in improving air quality underscores its importance in both residential and commercial settings.
