New Californian homes are generally being built tighter, but not exceptionally tight, like those found in colder climate regions.” Pre 1987 = 8.6 ACH50 Since 1992 = 5.2 ACH50 2003-07 = 4.8 ACH50 (Calif. Study Houses) In Maine, If an energy auditor tests your home and it is at or above 3.5 ACH50 you will be told that you have plenty of natural ventilation and that you do not need any additional.
