AixCaliBuHA: Automated calibration of building and HVAC systems

AixCaliBuHA enables an automated calibration of dynamic building and HVAC (heating, ventilation and air conditioning) simulation models. Currently, the package supports the calibration of Functional Mock-up Units (FMUs) based on the Functional Mock-up Interface (FMI) standard as well as Modelica models through the python-interface of the Software Dymola. As the former enables a software-independent simulation, our framework is applicable to any time-variant simulation software that supports the FMI standard.

Before executing the calibration, an automated sensitivity analysis can be performed to identify relevant parameters. As the derivative of simulations is typically not available, the optimization behind the calibration is solved by using already published gradient-free solvers. The whole process is visualized by optional progress plots to inform the user about convergence and design space exploration. Although the toolchain can be fully automated, users are free to perform semi-automatic calibration based on their expert knowledge.
