Workshop on Optimal Control of Thermal Systems in Buildings using Modelica

Monday, March 23, 2015, 12:30 - Tuesday, March 24, 2015, 18:30

Solar Info Center, Emmy-Noether-Str. 2, Freiburg 79110, Germany

Dear Participants,

welcome to the webpage for the two day Workshop on Optimal Control of Thermal Systems in Buildings using Modelica on March 23rd and 24th, 2015!

Aim of this interactive workshop is to bring together researchers that work on optimal control of thermal energy systems in buildings and who use or want to use the Modelica language for the building simulators. A major question of interest is how to connect Modelica based simulation tools with state-of-the-art optimization tools, and which problem formulations make sense.

On these pages, the workshop program can be found as well as the presentations and introduction slides of the individual participants.

The book of abstracts that will be distributed at the workshop is also available for download here.

We wish you exciting and inspiring two days!

Yours sincerely,
the organizers

Lieve Helsen (KU Leuven),
Adrian Bürger (HS Karlsruhe / Univ. Freiburg),
Christine Paasch (Univ. Freiburg) and
Moritz Diehl (Univ. Freiburg / KU Leuven)
