What is the primary role of ventilation in housing sanitation?

Ventilation plays a crucial role in maintaining indoor air quality by allowing fresh outdoor air to circulate within indoor environments while exhausting stale air, pollutants, and moisture. This process helps to dilute and remove indoor air contaminants, such as volatile organic compounds (VOCs), carbon dioxide, and allergens, which can accumulate in poorly ventilated spaces. By ensuring that there is adequate airflow, ventilation minimizes the risk of respiratory issues and promotes overall health and well-being for residents.

While reducing energy costs, enhancing sound insulation, and preventing pest infestations are important aspects of building design and functionality, they are not the primary objectives of ventilation. Instead, the focus remains on sustaining a healthy indoor environment and ensuring that occupants are not exposed to harmful concentration levels of pollutants, further emphasizing the significance of ventilation in housing sanitation.
