What is the primary function of building ventilation in indoor air quality management?

The primary function of building ventilation in indoor air quality management is to help reduce indoor contaminants. Proper ventilation ensures that there is a continuous exchange of indoor air with outdoor air, which helps dilute and remove pollutants such as volatile organic compounds (VOCs), carbon dioxide, mold spores, and particulate matter from indoor environments. This exchange is vital for maintaining a healthy living or working space, as it decreases the concentration of harmful substances that can accumulate in sealed environments.

While increasing humidity levels, enhancing aesthetic appeal, and controlling outdoor temperatures are important considerations in building design and comfort, they do not address the core purpose of ventilation in relation to indoor air quality. The essential goal of effective ventilation systems is to provide a safe and healthy atmosphere by minimizing harmful pollutants through adequate air exchange.
