Intent
Intent 1: 
To limit the probability that the performance of skylights will fall significantly below expectations with respect to:
  • structural strength and integrity, and
  • protection against condensation and precipitation ingress.
This is to limit the probability of:
  • the inadequate control of relative humidity or water accumulation,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of environmental separators.
This is to limit the probability of:
  • negative effects on the air quality of indoor spaces,
  • the inadequate thermal comfort of persons, and
  • contact with moisture.
This is to limit the probability of harm to persons.
