This wiki describes the specification and the implementation of the Building Controls Virtual Test Bed (BCVTB). The BCVTB is a software that allows expert users to couple different simulation programs for distributed simulation.

In addition to using programs that are coupled to Ptolemy II, Ptolemy II's graphical modeling environment can also be used to define system models for physical devices, communication systems or for post processing and real-time visualization. This coupling middleware allows to extend EnergyPlus' capabilities for controls simulation and for system simulation.
Typical applications include:
- performance assessment of integrated building energy and controls systems,
- development of new controls algorithms, and
- formal verification of controls algorithms prior to deployment in a building in order to reduce commissioning time.
Examples are provided with the BCVTB that show how to do distributed simulation. In the examples, we linked the following programs to the BCVTB:
a development version of EnergyPlus
- MATLAB/Simulink
- Dymola
- a simulation program implemented in C
- a simulation program implemented in Fortran 90
