Intent 1:
To limit the probability of an ineffective mixing
of ventilation air with room air, which could lead to stratification
near the floor due to the potentially cooler temperature and higher
density of ventilation air, which could lead to:
- an inability to maintain the minimum indoor air temperatures
[see Sentence 9.33.3.1.(1)], or
- inadequate ventilation.
This is to limit the probability of:
- the inadequate control of airborne pollutants or relative
humidity, or
- condensation.
This is to limit the probability of:
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- the deterioration of building elements.
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.
