Do Houses Need to Breathe?

This is one of the big misconceptions that still plagues so many home inspectors. I see it claimed almost daily on inspection boards and forums. I can only assume they once heard an old timer say that a house "needs to breathe", and they repeat it without knowing better. The problem is that they may erroneously attribute many issues to "poor ventilation" because they lack an understanding of building science. It is an easy mistake to make, because it has been repeated and ingrained in us for so long. Matt Risinger presents this topic exceptionally well, and I truly appreciate all he does to educate and inform. Check out his youtube channel is you are wanting more information. And for more information on building science, be sure to google Joseph Lstiburek (yes, that is the correct spelling). His presentations are well worth watching.
