Really air tight homes sometimes have air quality issues because there is not circulation. There is a reason it is more expensive to build homes like that--it comes with other problems that take specialized knowledge about things like ERVs to build them.
- Karrot_Kream 4y agoYou can still put windows in airtight homes. They're usually triple paned to insulate well, but nothing is stopping a builder from putting windows in. Most passivhauses do this. ERVs are additional engineering needed for when all the windows in the house are closed, but yes are necessary in those situations. ERVs aren't really that much more expensive than an exhaust that needs to be added in most homes anyway to release ventilation/dryer exhaust/cooking fumes. Only the really, really old homes don't have something like this and many of them have chimneys.
- danans 4y agoHRVs/ERVs are not specialized knowledge, they are just uncommon knowledge at the moment. They are even simpler to install than heating/cooling systems, as there is no fuel or refrigerant to deal with. Many are even DIYable.
