Questions and Answers

Which of the following is true about hygrothermal physical processes?

  • They are not affected by the conditions
  • They are not important in building systems
  • They always attempt to reach equilibrium (correct)
  • They always move from less to more

    • What does a good building envelope do?

  • Does not affect the indoor conditions
  • Allows the outside in and the inside out
  • Has no impact on the building's performance
  • Keeps the outside out and the inside in (correct)

    • If there is no intervention, what will happen to the conditions on both sides of an assembly?

  • They will become more extreme
  • They will switch places
  • They will eventually equalize and be in equilibrium (correct)
  • They will remain the same forever

    • Why do we attempt to change indoor conditions?
