Library with models for building energy and control systems


Package Buildings is a free package
for modeling building HVAC systems. 
It provides partial models and model
components for modeling thermal building systems 
such as heating, ventilation and air-conditioning systems. 
Many models are based on models from the package
Modelica.Fluid and use
the same ports to ensure compatibility with models from that library.

The figure below shows a section of the schematic view of the model Buildings.Examples.HydronicHeating. In the lower part of the figure, there is a dynamic model of a boiler, a pump and a stratified energy storage tank. Based on the temperatures of the storage tank, a finite state machine switches the boiler on and off. The heat distribution is done using a hydronic heating system with a three way valve and a pump with variable revolutions. The upper right hand corner shows a simplified room model that is connected to a radiator whose flow is controlled by a thermostatic valve.

Contributions may not only be in the form of model development, but also through model use, model testing, requirements definition or providing feedback regarding the model applicability to solve specific problems.
