Hi guys !

We’re building a mini exercise swimming pool in our future basement (of existing wooden framed 150 year old house in Montreal Quebec Canada).

The room 10 by 14 and 8 ft high is designed to be almost as good as passive haus norms : air tight and very well thermo insulated.

Our question :

How much air change(CFM) do we need to target for 2 hours of usage per day of an indoor mini swimming pool of 90 sqft (6’6” x 13’6”) when air is at 82 F and water at 80 F ?

Thank you very much !
