The advantages of natural ventilation are many and can have a tremendous positive impact on its occupants, building and the environment. A proper design, operation and maintenance of the ventilation system is essential in providing indoor air that is free of harmful concentrations of pollutants. Improvements in indoor ventilation may substantially increase an individual’s health, moral and productivity.
Ventilation is important as it reduces unhealthy air pollutants, such as formaldehyde and radon. It reduces excessive moisture and humidity levels, which can lead to mold growth and can cause structural damage. Ventilation reduces naturally occurring odors in the house from pets, cooking, smoking, and other everyday living activities.
