Question

Quizplus · Accepted Answer

The term "thermal envelope" refers to all building surfaces that separate heated space from unheated space, including walls, windows, ceilings, doors, foundation, etc. This envelope is what allows a building to maintain a comfortable temperature and reduces the need for energy consumption. Therefore, option A is the correct answer. Option B is incorrect because heat load variables refer to the factors that affect the amount of heat needed to maintain a comfortable temperature inside a building. Option C is incorrect because "resistance factors" are comprehensive and could refer to many things, not just the building's surfaces. Option D is not a commonly used term in the field of building construction and energy efficiency.
