Why is proper ventilation important in residential spaces?

Proper ventilation is crucial in residential spaces primarily because it helps maintain air quality and comfort. Good ventilation systems work by replacing stale indoor air with fresh outdoor air, effectively diluting indoor pollutants such as allergens, dust, and harmful gases like carbon dioxide or volatile organic compounds (VOCs). This exchange not only ensures that the air remains healthy to breathe but also contributes to overall comfort by regulating temperature and humidity levels.

Inadequate ventilation can lead to a buildup of moisture, which may result in mold growth and a range of health issues for residents. Therefore, effective ventilation is essential for creating a safe and pleasant living environment, making it a fundamental aspect of residential design and building codes.
