A blower-door test performed on a completed home measures PRIMARILY the building's:
a.Air leakage (envelope tightness)
b.Total insulation R-value
c.Duct system capacity
d.Window solar heat gain
Explanation
A blower-door test pressurizes or depressurizes the house to quantify uncontrolled air leakage through the envelope. It does not directly measure insulation R-value, duct capacity, or window solar heat gain, which are evaluated by other methods.
