6.2.3.15.(2)

Intent 1:

To limit the probability that an inappropriate type of fan or associated air handling equipment will be unable to withstand expected weather conditions, which could lead to failure, which could lead to:

• an inability to maintain adequate indoor air temperature or to control relative humidity, which could lead to condensation, which could lead to the growth of mould and mildew, or
• the inadequate control of airborne pollutants.

This is to limit the probability of negative effects on the air quality of indoor spaces, which could lead to harm to persons.
