Intent 1:

To limit the probability that:

  • pollutants or water vapour will not be removed from the building, or
  • when an exhaust system is not in operation and conditions of positive wind or stack effect pressure exist, airborne contaminants (e.g. exhaust fumes from a parking garage) will enter the building.

This is to limit the probability of negative effects on the air quality of indoor spaces, which could lead to harm to persons.
