Simulation Research

Simulation Research researchers specialize in the research, development and deployment of software that supports building design and operation, as well as the research of next-generation building energy and control systems.

Programs developed by ETA researchers include the following:

The Simulation Research Group is leading, with RWTH Aachen, the International Energy Agency's Annex 60, which is developing new-generation computational tools for building and community energy systems based on the Modelica and Functional Mockup Interface standards.

The Simulation Research Group is also leading, with Tsinghua University, China, the IEA EBC Annex 66 ( definition and simulation of occupant behavior in buildings. Our behavior research ( focuses on energy-related occupant behavior, using advanced data analytics, modeling and simulation, to reduce energy sue in building and improve occupant comfort.
