We are pleased to announce the release of the Building Controls Virtual Test
Bed 1.2.
The following changes have been made compared to version 1.1:
* ESP-r has been added as a client program.
* The example files have been updated for EnergyPlus 7.2.
* The example files have been updated for EnergyPlus 7.1.
* A buffer overflow has been fixed which causes the error message ***stack
smashing detected ***, followed by a termination of the client program.
* An example file has been added that describes how to convert an array of
strings into an array of doubles.
The Building Controls Virtual Test Bed (BCVTB) is a freely available
open-source software environment that allows expert 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,
* the Modelica modeling and simulation environment Dymola,
* the MATLAB and Simulink tools for scientific computing,
* the Radiance ray-tracing software for lighting analysis,
* the ESP-r integrated building energy modeling 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.
