Building Controls Virtual Test Bed

The Building Controls Virtual Test Bed (BCVTB) is a software environment that allows users to couple different simulation programs for co-simulation, and to couple simulation programs with actual hardware. For example, the BCVTB allows to simulate a building in EnergyPlus and the HVAC and control system in Modelica, while exchanging data between the software as they simulate. The BCVTB is based on the Ptolemy II software environment. The BCVTB allows expert users of simulation to expand the capabilities of individual programs by linking them to other programs. Due to the different programs that may be involved in distributed simulation, familiarity with configuring programs is essential.
Programs that are linked to the BCVTB are
the EnergyPlus whole building energy simulation program,
Functional Mock-up Units (FMU) for co-simulation and model-exchange for FMI 1.0 and 2.0,
the Radiance ray-tracing software for lighting analysis,
the ESP-r integrated building energy modeling program,
the TRNSYS system simulation program,
the BACnet stack, which allows exchanging data with BACnet compliant Building Automation System (BAS),
the analog/digital interface USB-1208LS from Measurement Computing Corporation that can be connected to a USB port.
In addition to using programs that are coupled to Ptolemy II, Ptolemy II's graphical modeling environment can also be used to define models for control systems, for physical devices, for communication systems or for post-processing and real-time visualization.
Typical applications of the BCVTB 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.
The coupling of Modelica allows using EnergyPlus for modeling the building heat flow and daylight availability and using Modelica to model innovative building energy and control systems based on the library that is currently in development at http://simulationresearch.lbl.gov/modelica. This allows advanced users to
define on the fly new HVAC components and systems in a modular, hierarchical, object-oriented, equation-based graphical modeling environment and couple them to EnergyPlus,
