Workshop on Optimal Control of Thermal Systems in Buildings using Modelica location:University of Freiburg date:23 - 24 March 2015
One of the current bottlenecks in the implementation of MPC in buildings is the required controller model. Each building needs its own model of which the development currently involves a lot of manual work. A solution can be found in data-driven modelling techniques.
This presentation describes the development and validation of a grey-box modelling toolbox for buildings.
The Python toolbox is developed based on a Modelica library with thermal building and Heating, Ventilation and Air-Conditioning (HVAC) models and the optimisation framework in JModelica.org.
The toolchain facilitates and automates the different steps in the system identification procedure, like data handling, model selection, parameter estimation and validation.To validate the methodology, different grey-box models are identified for a single-family dwelling with detailed monitoring data from two experiments.
This presentation will cover the methodological aspects of the toolbox and discuss the resulting models and their validation for a single-family dwelling in Munich (Germany) and an office building in Brussels (Belgium).
