Sentence 9.15.1.3.(1)

Intent 1:

To limit the probability that the performance of detached buildings, with respect to longitudinal or torsional stiffness, will fall significantly below expectations, which could lead to an inability to resist expected loads transferred from the superstructure to individual foundation elements.

Where elements support or are part of an environmental separator, this is to limit the probability of excessive deformation, which could lead to damage to the superstructure, which could lead to:

• condensation,
• rainwater ingress, or
• compromised thermal performance of components intended to provide resistance to heat transfer.

This is to limit the probability of:

• an inadequate control of temperatures of interior spaces, relative humidity, or water ingress and accumulation,
• the generation of pollutants from biological growth or from materials that become unstable on wetting, or
• compromised integrity of the environmental separator, which could lead to the deterioration of building elements.

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.
