Similar with the building rules in the Netherlands. Houses must have passive ventilaton in each (bed)room, and some system to create at least a certain amount of airflow based on the size of the house.
Simplest way is passive vents on the windows and a central blow-out fan that pulls air in. The more modern way uses a heatexchanger setup to take heat from the outflowing air and use it to warm air being pumped into the house.
