- 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:
- 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.
