The conference takes place in one of the central buildings of the University of Freiburg. It is called "Kollegiengebäude I" or short "KG I". The official address is
Platz der Universität 3,
79098 Freiburg.
In the KG I, you need to find the "Aula".
Here, you find the KG I on a google map:
Note that the KG I is not the math building!
