Intent 1:
To limit the probability that the installation of
heating or air-conditioning equipment and coupled ventilation systems
will fall significantly below expectations, which could lead to inadequate
performance or failure, which could lead to:
- an inability to maintain adequate indoor air temperatures,
which could lead to condensation, or
- the inadequate replacement of indoor air with outdoor
air or the distribution of outdoor air.
This is to limit the probability of:
- the inadequate control of relative humidity,
- the generation of pollutants from:
- harmful micro-organisms and the media they grow on,
- biological growth, or
- 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.
