The comment you are responding to discusses air exchange systems to supply more fresh air than simply dealing with a leaky old house. So both absolutely more wasteful and also less enjoyable than a modern and well-designed system.
- samatman 5y agoI'm fairly certain you two are speaking completely past each other about radically different climates.
- wcarron 5y ago> One example? In Canada we have a standard for air tightness, and more, called R-2000. Houses with this standard have to have heat exchangers, for they are so airtight, that they require air be circulated in from outside. When it is -40C, this change can mean heating costs of 200/month vs 2000! This *is* what we call a modern and well-designed system.
