From greenhouse dimensions and target air changes per hour, estimate the required ventilation rate and fan configuration to keep temperature and humidity in range.
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Air exchange rate | n = Q / V | ASABE EP406.4 |
| Minimum winter ventilation | 0.5-2 ACH for dehumidify | ASABE D270.5 |
| Infiltration allowance | Add 0.5-1.0 ACH | ASABE EP406.4 |
