The Modelica Buildings library is a free open-source library with dynamic simulation models for building energy and control systems. The library contains models for
- air-based HVAC systems,
- water-based heating systems,
- heat transfer among rooms and the outside, and
- multizone airflow, including natural ventilation and contaminant transport.
The primary use of the library is for flexible and fast modeling of building energy and control systems to accelerate innovation leading to cost-effective very low energy systems for new and existing buildings.
