The Simulation Research Group specializes in the research, development and deployment of software that support the design and operation of buildings, as well as the research of next-generation building energy and control systems. As the former developer of the DOE-2.1 and the SPARK software, the group is now developing:

The Simulation Research Group is also leading, together with RWTH Aachen, the IEA EBC Annex 60. Annex 60 is developing new generation computational tools for building and community energy systems based on the Modelica and Functional Mockup Interface standards.
