what are the disadvantage of the natural ventilation?

Public Comments

1. It are the fresh of air.
2. Dust pollution, noise, birds flying into you house and taking a dump just anywhere. Its of course nice and windy but you'll need to clean up later
3. In a building? If that is the case then the disadvantage of natural ventilation would be having to be prey to the elements. If it is hot outside, then it will probably be hot inside. If it is freezing cold, you will probably get the same or similar conditions inside where you are.
