AixLib is a Modelica model library for building performance simulations.
The library contains models of HVAC systems as well as high and reduced order building models.
It is being developed at RWTH Aachen University, E.ON Energy Research Center, Institute for Energy Efficient Buildings and Indoor Climate (EBC) in Aachen, Germany.

As the library is developed at RWTH Aachen University's EBC, the library's name AixLib is derived from the city's French name Aix-la-Chapelle, which the people of Aachen are very fond of and use a lot. With the name AixLib we follow this local tradition.
