Fine dust is also present INSIDE the house. Not in huge amounts, but what do you think is the stuff you regularly have to clean up in, on, and around the fireplace?
Fireplace in a new house I already had. Sure, it's cozy. But also a lot of dirt and extra work. And before you know it, the place is totally overheated.
The house now (still under construction) will be EVEN better insulated and EVEN tighter. Fireplace? Nooo. No more desire!
