ERV/HRV planning worksheet
ERV/HRV Selection Worksheet
Organize climate, humidity goal, airflow, filtration, access, and model data needs before fresh air equipment review.
ERV latent review HRV sensible review CFM fresh air target Filter service path
Calculator Steps
Input Workflow
ERV vs HRV reviews should start with climate and building operation, then move to airflow, access, filtration, and model data.
Identify whether humidity transfer, sensible heat recovery, filtration, or service access is the main concern.
Keep duct path, drain or condensate expectations, filter access, and maintenance space visible.
Attach the worksheet to fresh air/ERV equipment review instead of treating ERV vs HRV as a loose label choice.
Keep recovery, airflow, filter, sound, electrical, and certification details tied to the selected model.
Result Notes
Calculation Output
The output helps decide what to ask next. Code compliance and certification remain project-specific.
Climate and humidity
Humid, cold, dry, and mixed climates can change whether latent transfer is useful.
Keep the climate note attached.Airflow target
ERV/HRV selection needs CFM context before equipment comparison.
Planning CFM value.Filter and access
A unit that cannot be serviced cleanly can fail in operation even if airflow looks right.
Confirm maintenance access.Model data
Recovery, airflow, filter, sound, electrical, and certification details belong with the selected model.

ERV HRV Matrix
| Project condition | Project facts | Equipment family | Review note |
|---|---|---|---|
| Humid cooling season | Humidity goal, CFM, filter, drain/access notes | Fresh air and ERV systems | Latent transfer should be checked |
| Cold heating season | Outdoor design context, indoor humidity, frost/access notes | ERV/HRV review | Match recovery type to climate |
| Occupied classroom or office | Occupancy, CFM, sound, filter access | Fresh air and ERV systems | Sound and service access matter |
| Gym or active space | Peak occupancy, humidity, odor, filtration | ERV plus dehumidifier review | Moisture and ventilation may need both paths |

Technical FAQs
Does this choose a final model?
No. It organizes project information so the distributor team can identify the next technical detail to review.
What separates an ERV review from an HRV review?
Humidity transfer, climate, indoor moisture goals, occupancy, and operating pattern shape the early ERV versus HRV discussion.
What installation details should be captured?
Capture duct route, filter access, service side, drain needs where applicable, controls, and available ceiling or wall space.
