Intent 1:
To limit the probability of:
- occupants being unable to control the principal ventilation
fan, and
- occupants having difficulty finding the principal ventilation
fan control or understanding the control's function.
This is to limit the probability that
occupants:
- will disconnect the fans, or
- will be unaware of their ability to control ventilation
fans, which could lead to fans not being used.
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, which could lead to harm to persons.
