0.5 ACH - House is a new, energy-efficient construction, or has been thoroughly weatherized by professionals. All doors and windows seal tightly, and no drafty areas are noticed within.
0.9 ACH - House is a recent construction (~2000), or an older home that has weatherstripping and seals in good repair. There may be some small gaps around doors and windows, or a few noticeable drafty places.
1.5 ACH - House is an older construction (~1990), or has several noticeable gaps around doors and windows. There will be several noticeably drafty areas that do not maintain temperature well.
2.0 ACH - House is much older, likely built without a central conditioning system. Remote rooms are uncomfortable during extreme temperature conditions (i.e. hot summer/cold winter conditions).
