Not sure where you live, but if air in my room circulated once in an hour, with doors/windows closed, I'd consider it way too much. We have winters so people tend to plug holes. You're not talking about HVAC, are you? Nevertheless, I do know people living in leaky homes/building, and they do get >1 exchange/hour. |
