Intent

Intent 1:

To limit the probability that the structural framing and perimeter areas of intersecting interior walls will not be considered in the calculation of the overall thermal transmittance of wall assemblies, which could lead to the underestimation of the overall thermal transmittance of wall assemblies, which could lead to excessive thermal transfer through the building envelope, which could lead to excessive use of energy, which could lead to an unacceptable effect on the environment.

Intent 2:

To clarify that the perimeter areas where floor or roof slabs interrupt the wall construction are not to be included in the calculation of the overall thermal transmittance of wall assemblies on the basis that their effect is addressed in Sentence (9).
