Intent 1:
To limit the probability that occupants will not
be able to turn off the principal ventilation system, which could
lead to their disconnecting the system, which could lead to a lack
of ventilation when required.
This is to limit
the probability of:
- inadequate ventilation, or
- the inadequate control of relative humidity.
This is to limit the probability of the inadequate control
of:
- indoor air temperatures,
- 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,
or
- the inadequate thermal comfort of persons.
This is to limit the probability of harm to persons.
