Intent 1:
To limit the probability that the performance of
mechanical ventilation systems will fall significantly below expectations.
This is to limit the probability of the inadequate control
of:
- airborne pollutants,
- oxygen and other components necessary for breathable
air, or
- relative humidity, which could lead to 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,
or
- the inadequate thermal comfort of persons.
This is to limit the probability of harm to persons.
