GEBA is a program for the simulation of the thermic behaviour of buildings. It calculates temperature changes of the air of the room and building components over the day as well as heating or cooling processes required for these temperature changes.

The program simulates the thermic behaviour of buildings in steady-state with a period length of 1 day. This makes it useful for assessments in accordance with EN ISO 13791.
The program and the documentation are available in German only.

More about GEBA can be read at the website of Prof. Klaus Krec, PhD.
