Large buildings like this often have service tunnels. Built in 1965 the building probably had radiators in the classroom. Have to move that steam around somehow. Sometimes they actually are used for nefarious purpose but usually not. Go to a lot of the colleges and Universities in the Northern tier and there are steam tunnels under the entire campus. Still fun to watch. Dudes girlfriend was shitting herself the whole time but bravely kept going.
