The Text Output Files, Drawing Files, and Spreadsheets buttons cause several different results files to open at once based on the currently selected Input File. The buttons on this tab can open many files at the same time and are a shortcut to opening the files that may be commonly used. The figure above shows the same main screen of EP-Launch but with the “Sets” tab selected on the left edge of the View Results section. The contents of each file extension is listed below.ĮP-Launch with the Sets tab of View Results Files available for view based on the current input file name are “enabled” (extension names clearly readable). The “All” tab shows all the various files by file extension that can be viewed individually. Two different panels of buttons can be used under View Results, one shown by using the “All” tab on the left edge and by using the “Sets” tab on the left edge. Alternatively, pressing the F2 function key will display the same three files.Īnother way to open files easily is by using the View Results buttons shown in Figure 3. After pressing “OK” from this box, selecting “ERR/EIO/BND Output Files Only” from the “View” menu will display the ERR, EIO, and BND files – useful when errors may have occurred. This status gives you a quick overview of whether there were warning ( should look at), severe ( should probably fix) or fatal ( must fix) errors in the run as well as the time it took for the simulation to complete. Looking at the Results Īfter you have run a simulation and the black DOS window closes, EnergyPlus has completed, and a status message is displayed see Figure 2:ĮP-Launch Finish Status On a computer with multiple-processors or multiple-cores, this will enable the simulations to complete more quickly than starting one after another. Multiple single input file and group simulations can be started at the same time.

If multiple simulations are performed, the output files will be listed on the History tab and will be named with either the file suffixes defined in the input file or with a serial number. If the file contains Parametric objects, the single input file may cause multiple simulations to be performed. To continue after the pause, press any key. If you would like to see these messages more slowly you have two options:ġ) Press the “Control-S” key combination to try to stop the progress and any key to continue.Ģ) Under the “View” menu on the EP-Launch program, select “Options” then “Command Window“ then check”Pause During Simulation" and this will pause the process immediately after EnergyPlus executes. The EnergyPlus program black DOS window will show scrolling text as the simulation procedure progresses. The simulation is complete when the black DOS box closes. At this point a black DOS window should pop up on your screen and show the progress of your simulation. On the Single Input File tab, after you select the weather and input files simply push the “Simulate…” button to start the EnergyPlus building energy simulation engine.
These are not the only examples, use browse to open other example files from the ExampleFiles subdirectory or other EnergyPlus input files. If this is your first time using EP-Launch, the pull down lists will show some files from the ExampleFiles subdirectory. The input file and weather files can be selected on the Single Input File tab from the two pull down lists which show recently used files or you can press the “Browse…” buttons to locate an input or weather file that you have created yourself. More help is provided for the program under the “Help” menu. The EP-Launch program simply starts other programs and allows you to avoid having to use the DOS command line prompt to run EnergyPlus. By double clicking on the EP-Launch icon you get the screen shown above (Figure 1) for running a single input file. In addition, it is available on the shortcut menu for EnergyPlus. EP-Launch Screen Start EP-Launch ĮP-Launch is located in the main directory/folder for EnergyPlus.
