You need two windows open at the same time. Get a through draught to change to change the air in the room frequently.That one is a bit odd as opening a window is more likely to push the air further in the room than out. As you say minimal time in any enclosed space is the sensible option.
Not comfortable with the temp outside at 0°C, and it plays havoc with the heating bill.
