Exaust fans for the bathrooms vs ERV
Trying to understand how the bathroom exhaust works with ERVs.
We originally had independent bathrooms fans planned for each bathroom, in addition to normal air supply and exhaust via ERV.
The suggestion is to not add roof openings for example in the upper floor bathrooms, and instead rely on ERV somehow to vent the bathrooms, without installing the fans.
That sounds like a bad idea. Is it?
