Workshop Exergy-based Control Strategies for HVAC Systems

  Roozbeh Sangi and Marc Baranski EBC

Roozbeh Sangi and Marc Baranski held a workshop on the project “Exergy-based Control Strategies for HVAC Systems” at the Berliner Energietage 2018 in collaboration with TU Berlin. In the project, the application of exergy to the control of complex building energy systems was investigated. The focus of the project was on the improvement of energy efficiency while ensuring indoor air quality and thermal comfort. Roozbeh Sangi and Marc Baranski presented the main outcomes of the project to about twenty participants of the workshop. Roozbeh Sangi gave a talk on “Agent-based Control” and Marc Baranski talked about “Efficient control of a central air handling unit applying distributed model predictive control”. They demonstrated the applications of the two afore-mentioned control techniques to the building energy systems and discussed the advantages and disadvantages of each, especially if exergy is defined as the optimization objective. They also opened up discussions with the participants about the upcoming projects and the future of agent-based and decentralized model predictive controls in buildings and urban energy systems.
