Then, for each classroom you can specify the building where it is located:

Note:
- basically for most of the schools it is not necessary to input buildings, because entire education is located into one building, or into one campus (so buildings are very close and teachers/kids can move between lessons during breaks).

- also, use this option, if you need to specify different reports for substitution according buildings
