Our newer buildings don't have windows that open and have interior hallways, so some rooms don't have doors to outside. They have better building ventilation and per-room standalone air filters, though.

Even just a single door open makes a big difference, IMO.

I've never attended a school that had doors to the outside from the classroom, honestly. Most, but not all, had windows that open, though.
