Are there no health issues associated with a house being that well sealed, or do you have some sort of air exchanger that is temperature efficient?

Edit: e.g. googling brought up this article - https://www.architectsjournal.co.uk/buildings/airtightness-b...

You insulate and air seal properly, then make sure that you bring in outside air in a controlled fashion (enough CFM, filtered, etc):

I wonder what carbon dioxide levels get up to in a well-sealed house.

You’ll want mechanical ventilation (with heat recovery) to prevent that: https://en.wikipedia.org/wiki/Heat_recovery_ventilation

Heat recovery + well sealed house with some humans inside can potentially mean no heating at all!

Some good comments on that in this HN thread from a few weeks back. In short, not good.
