Intent

Intent 1:

To limit the probability that the nominal thermal transmittance of access hatches will be unacceptably high, 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 stiffeners and edge construction are not to be included in the determination of the nominal thermal transmittance of access hatches.
