Intent 1:

To limit the probability of an inadequate allowance for expansion and contraction of pipes from heating and cooling during service, which could lead to excessive stress in pipes, which could lead to pipe failure, which could lead to:

  • the escape of the heating medium or refrigerant, or
  • an inability to maintain the minimum indoor air temperatures [see Sentence 9.33.3.1.(1)], which could lead to condensation.

This is to limit the probability of:

  • the inadequate control of temperatures and relative humidity,
  • the generation of pollutants from 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.
