Welcome to BuildingControlLib, a Modelica library for modelling and simulation of standardized and non-standardized control functions from Building Automation Systems. The library is developed and maintained at the Fraunhofer Institute for Building Physics IBP in the Technical Building Systems Working Group in Nuremberg, Germany.
The model library BuildingControlLib is released by Fraunhofer Institute for Building Physics IBP under the Modelica License 2.0.
The libary uses models from the AixLib-library, version 0.4.0 and models of the Buildings-library, version 4.0.0.
The library has been tested with Dymola 2017 FD01 64bit on Windows 7 64bit.
The current version 0.1.0 is a pre-release.
