Download

The BCVTB release includes the binary files that are compiled for Windows. It also contains source code that can be compiled on Mac OS X, Linux and Windows. Compilation is only required for Mac OS X and Linux.

To install the BCVTB, proceed as follows:

1. Follow the user installation instruction. This is sufficient for most users.

2. Next, if you like to develop new code for Ptolemy or for the BCVTB interface, follow the developer installation instruction.

Note for users of Microsoft Internet Explorer: Internet Explorer may save the file with the extension .zip instead of .jar. To avoid this, click "Save Target As..." (using the right mouse button) and then enter the name of the installation file, for example, bcvtb-install-0.6.0.jar. (Or use Firefox to avoid this problem.)

3.2. Release notes

This version contains the following updates:

1. Added a compact schedules to the EnergyPlus interface.

2. For the EnergyPlus interface, changed variable names in xml configuration file variables.cfg. The following name changes have been made

     dayschedule	(Replaced by schedule)
     n/a	schedule

Note that the new object schedule is similar to the Schedule:Compact in EnergyPlus and hence should not be used with a Schedule:Week.

  • old	new
    BCVTB	ExternalInterface
    PtolemyLink	PtolemyServer
    Schedule:Day:Dynamic	(replaced by ExternalInterface:Schedule)
    n/a	ExternalInterface:Schedule
    n/a	ExternalInterface:Actuator

  You will have to manually update your idf files from earlier BCVTB versions. See also Configuration/EnergyPlus for how to configure EnergyPlus.

• ep-3.1.zip This zip-file requires a password. It is the same file as the one that is distributed with the BCVTB version 0.2.0. To obtain the password, email the password of the official EnergyPlus installation to ZhengweiLi.

4.2. Release notes

This version contains the following updates:

1. Added a new actor called SystemCommand that allows to call any system command from Ptolemy. See the example for further information.

2. Added option to start the BCVTB from a java jar file. This allows to start the BCVTB from a file explorer or from a command line with several options. See Files/BCVTBJar for a description.

3. Added the example examples/dymolaEPlus31-singleZone, in which an air-based HVAC system that is modeled in Modelica is linked to a building model of EnergyPlus.

• ep-3.1.zip This zip-file requires a password. It is the same file as the one that is distributed with the BCVTB version 0.2.0. To obtain the password, email the password of the official EnergyPlus installation to ZhengweiLi.

5.2. Release notes

This version is a minor update that addresses the following issues:

1. For the Simulink interface, fixed a bug that prevented the BCVTB library to be displayed in Simulink's library browser.
2. Fixed compilation problems on Mac OS X 10.6 (Snow Leopard).

6. Release 0.3.0 (August 24, 2009)

6.1. Download

• bcvtb-install-0.3.0.jar

• ep-3.1.zip This zip-file requires a password. It is the same file as the one that is distributed with the BCVTB version 0.2.0. To obtain the password, email the password of the official EnergyPlus installation to ZhengweiLi.

6.2. Release notes

1. This version contains a subset of Ptolemy. Users do not need to install their own Ptolemy version.
2. Cygwin is not required anymore.

3. In the files variables.cfg, the header needs to look like

   <?xml version="1.0" encoding="ISO-8859-1"?>
   <!DOCTYPE BCVTB-variables SYSTEM "variables.dtd">
   <BCVTB-variables>

   i.e., you need to add the second line to your existing file.

4. Due to shipping a new Ptolemy version, the files system.xml and system-windows.xml had to be changed. Previous files can be updated by running the following bash script from the examples directory fixModels.sh.

7. Release 0.2.0 (June 30, 2009)

7.1. Download

• bcvtb-install-0.2.0.jar

• ep-3.1.zip This zip-file requires a password. To obtain the password, email the password of the official EnergyPlus installation to ZhengweiLi.

7.2. Release notes

1. The parameters of the Ptolemy Simulator object changed. To update your files system-windows.xml (or system.xml on Linux or Mac), run from cygwin (or a bash shell) the command

   $BCVTB_HOME/bin/updateSystemFiles.sh system-windows.xml

2. The EnergyPlus object DAYSCHEDULE:DYNAMIC has been renamed to SCHEDULE:DAY:DYNAMIC.

3. Due to a change in the parameters of the Simulator object, file names must not be quoted anymore. I.e., in system.xml or in system-windows.xml, change "socket.cfg" to socket.cfg.

4. The Simulator object now writes the simulation output to a log file (default is simulation.log) and to the console. However, console output is currently only working on Linux and on Mac OS X. The reason is that Ptolemy on Windows is started using javaw which does not write the output stream to the console.

5. The build system has been changed from Makefiles to Apache Ant. Cygwin is still needed to compile Ptolemy on Windows, but the compilation of the BCVTB does not require cygwin anymore.
