My elementary schools were 1) L-shaped single story with classrooms ringing the exterior perimeter, 2) traditional 5 story brick with an atrium so both interior and exterior rooms got natural light. Middle school was single story again. High school was traditional 3 story brick. The only rooms without natural light were basement rooms (for band, theatre & ROTC) under the auditorium, which I think was 100% acceptable.
