Intent
Intent 1: 
To limit the probability of inadequate ventilation, which could lead to the inadequate control of:
  • airborne pollutants,
  • oxygen and other components necessary for breathable air, or
  • condensation, which could lead to the generation of pollutants from biological growth or from materials that become unstable on wetting.
This is to limit the probability of negative effects on the air quality of indoor spaces, which could lead to harm to persons.
