The following people from Berlin University of the Arts, Institute for Architecture and Urban Planning, have directly contributed to the implementation of the BuildingSystems library
The core of this library is the Modelica IPBSA library, a free open-source library with basic models that codify best practices for the implementation of models for building and community energy and control systems.
