Intent 1:
To limit the probability that the performance of
heating-season 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.
