- Required outdoor air
- 1,200 CFM
- Volume
- 6,000 cu ft
- No recirculation between wards
- Recommended to prevent cross-ward disease spread
- Humidity target
- 30-70% RH to limit pathogen survival
Quick answer
Animal shelter housing areas are commonly ventilated at 10-15 outdoor air changes per hour to reduce airborne disease transmission and control odour, per shelter design guidelines.
CFM = volume x ACH / 60

Frequently asked questions
Why so much outdoor air compared to a home?
High animal density and disease risk (e.g. kennel cough, parvovirus) call for aggressive dilution ventilation, much higher than residential rates.
Can HVAC recirculate shelter-wide?
Best practice isolates airflow by ward so an outbreak in one area is not spread through shared return ductwork.
What do I need to enter into the Animal Shelter Ventilation Calculator?
Just 3 values: housing area, ceiling height, air changes. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
How does the Animal Shelter Ventilation Calculator work out the answer?
Animal shelter housing areas are commonly ventilated at 10-15 outdoor air changes per hour to reduce airborne disease transmission and control odour, per shelter design guidelines. It applies the formula CFM = volume x ACH / 60 and shows the working so you can check each step by hand.
