Final answer:
True, an inspector should describe the exterior wall covering as it is an essential part of a building's envelope and affects energy efficiency. Half the thickness consideration is due to partial heating of the wall.
Step-by-step explanation:
The statement in the question is true: an inspector should describe the exterior wall covering. This is because the exterior wall covering is an important component of a building's envelope, which provides protection against the elements and contributes to the overall energy efficiency of the structure.
True, an inspector should describe the exterior wall covering as it is an essential part of a building's envelope and affects energy efficiency.
Half the thickness consideration is due to partial heating of the wall. Additionally, when calculating the energy performance or thermal properties of a building, only half the thickness of the exterior walls is considered, since they are not heated to the interior temperature all the way to the outside.
