  1. OH1

Objective

OH1 Indoor Conditions

Attribution

Intent

Intent 1:

To limit the probability that:

  • the outdoor air supply from a heat recovery ventilator will exit a building through another heat recovery ventilator that is not operating, which could lead to an inadequate distribution of fresh air to the intended rooms or spaces, or
  • the airflow of another heat recovery ventilator will be disrupted.

This is to limit the probability of inadequate ventilation, which could lead to the inadequate control of:

  • airborne pollutants,
  • oxygen and other components necessary for breathable air, or
  • relative humidity, which could lead to condensation, which could lead to the generation of pollutants from biological growth or from materials that become unstable on wetting.

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