All targets are based on ACH measurement at 50 pascals pressure.
| Program | Attached | Detached |
| Energy Star | 3.0 | 2.5 |
| R2000 | 1.5 | 1.5 |
| Net Zero | 1.5 | 1.0 |
| Passive House | 0.6 | 0.6 |
Note: these targets are based on NEW construction, and so would involve an energy model that prescribes a target.
For renovation and retrofit, blower door testing can establish a baseline ACH.
Older buildings may have as much as 10 - 15 air changes per hour, so improving upon the airtightness can almost be guaranteed by a good renovation plan.
