Intent 1:
To limit the probability that the thermal performance
of required thermal insulation will fall significantly below expectations,
which could lead to an inability to control heat transfer through
assemblies, which could lead to:
- excessively low temperatures of interior surfaces or
within assemblies, or
- condensation.
This is to limit the probability of:
- an inadequate control of the temperature of interior
spaces or relative humidity,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- deterioration, which could lead to compromised integrity
of assemblies acting as environmental separators.
This is to limit the probability of:
- negative effects on the air quality of indoor spaces,
and
- the inadequate thermal comfort of persons.
This is to limit the probability of harm to persons.
