Intent 1:
To limit the probability that loose connections
or unnecessary openings will lead to excessive air leakage, which
could lead to:
- the inadequate delivery of warm air or the return of
cold air, which could lead to:
- an inability to maintain adequate indoor air temperatures,
or
- the inadequate control of:
- relative humidity or indoor air temperatures, or
- surface temperatures, or
- inadequate ventilation, which could lead to the inadequate
control of:
- relative humidity, which could lead to condensation,
which could lead to mould and mildew growth,
- airborne pollutants, or
- indoor air temperatures.
This is to limit the probability of:
- negative effects on the air quality of indoor spaces,
and
- the inadequate thermal comfort of persons.
This is to limit the probability of harm to persons.
