Yes, the Monolithic Dome is much more airtight than a conventional building. This has obvious energy efficiency advantages. However, it also creates the need to provide for fresh air into the home.
In every Monolithic Dome home the vents from the bathroom and the kitchen range must vent outside. This, combined with the use of the family clothes dryer, will provide enough pull on fresh air into the home to be more than adequate. There is one exception — if a lot of indoor pollution is brought inside, such as smoking, it is recommended to have an air-exchanger for a more consistent exchange of air.
