Panasonic WhisperSupply vs exhaust-only ventilation
I’ve read here that supply-only ventilation might be a better choice than exhaust-only.
I have a 12×16 art studio/guest room with vaulted ceiling in climate zone 5b (1680 ft³). I’m unsure how tight it will be, we are doing as much as we can with airtight drywall, yet it has weak points like a low-end french door and a few cheap sliding windows.
HRVs like Lunos and TwinFresh are out of budget. I had planned to use a Panasonic bath fan (FV-0511VK2) at it’s lowest setting on a timer. No bathroom, the fan is just for ventilation.
What cfm/air exchange should I be shooting for with this small building?
Would a Panasonic WhisperSupply fan (FV-01WS2 or FV-04WS2) be a better alternative to the bath fan? Or is it something I should consider adding to my existing plan?
Seems unreasonable in winter to blow untempered cold air in, but I wonder will the exhaust-only system be any more comfortable or efficient in terms of heat gain/loss?
