Information

IDEAS is a Modelica library for Integrated District Energy Assessment Simulations. This free and open-source library enables simultaneous transient simulation of integrated thermal and electrical energy systems including buildings at both individual (building) and collective (district) level. The IDEAS library extends from the Modelica IBPSA library and has a particular focus on the development of detailed building models. It is one of the four sister libraries that extend from the core Modelica IBPSA library, alongside AixLib, Modelica Buildings, and BuildingSystems. IDEAS clearly differs from existing building energy system simulation tools by integrating the dynamics of all hydronic, thermal, and electrical components at both the building and aggregated level within a single model and solver.

Content

Main packages are listed below:

• Buildings contains component models for modelling building envelopes.
• Fluid contains component models for modelling fluid systems.
• Examples contains example models that demonstrate the use of Buildings and Fluid.

Package and model specific documentation can be found in the respective User's Guides and model documentation.

Feedback

IDEAS is developed at GitHub. Feel free to create an issue in case you have a problem or a suggestion.
