IBPSA library is a free library
that provides more than 300 classes (models, functions, etc.) for the development of
Modelica libraries for building and community energy and control systems.
The library is compatible with models from the Modelica Standard Library,
in particular with models from
The development of the IBPSA library is organized through the IBPSA Project 1 of the International Building Performance Simulation Association (IBPSA). From 2012 to 2017, the development was organized through the Annex 60 project of the Energy in Buildings and Communities Programme of the International Energy Agency (IEA EBC).
The intent of the library is that it will be extended by implementations of Modelica libraries that are targeted to end-users. Major goals are
Hence, this library is typically not used directly by end-users,
but rather by developers of libraries that will be distributed to end-users.
Libraries that are using the
IBPSA library as their core, or
that are working on using the
IBPSA as their core, include, in
AixLib library from RWTH Aachen, Germany, available at
Buildings library from Lawrence Berkeley National Laboratory, Berkeley, CA, available at
BuildingSystems library from
Universität der Künste Berlin, Germany,
IDEAS library from KU Leuven, Belgium, available at
The library also contains more than 300 example and validation models. For Dymola, each of these example and validation models contains a script that simulates it and plots certain variables of interest.
The web page for this library is https://github.com/ibpsa/modelica. Contributions to further advance the library are welcomed. Contributions may not only be in the form of model development, but also through model use, model testing and validation, requirements definition or providing feedback regarding the model applicability to solve specific problems.
