Amount of insulation in the house
Rate of air return in the ductwork

The correct answer is: Volume of air that leaks into or out of a building

This measurement is crucial because it helps HVAC professionals assess the efficiency of a system and determine if there are any air leakage issues that need to be addressed. Options A, B, and D are incorrect because they do not directly relate to the concept of air leakage in a building, which is specifically indicated by the term "cfm (infiltration)."
