PROBLEM TO BE SOLVED: To provide a method for easily measuring the airtightness of a building without requiring exclusive airtightness measurement facilities, or the like. SOLUTION: In the method for measuring the airtightness of a unit-type building 1 according to pressure differenceΔP inside and outside the unit-type building 1, a supply and exhaust fan 20 being used as supply and exhaust facilities being provided at the unit-type building 1 in advance, and a range fan 30 in a kitchen are used for sucking or exhausting air, thus generating the pressure differenceΔP inside and outside the unit-type building 1, and hence measuring the airtightness of the unit-type building 1. By the method, the airtightness of the unit-type building 1 is easily measured without requiring exclusive airtightness measurement facilities, ducts, or the like.
