The Energy+.ini file is read by the EnergyPlus.exe program and is very important to the simulation run. In specific, this file contains a pointer to where the Energy+.idd file will be found. More description of the Energy+.ini contents is contained in the Auxiliary Programs document.
For the advanced user, there is also the “EPMacro” program, described in the Auxiliary programs document. You run it as a separate program before EnergyPlus (the batch file included in the install and shown in the GettingStarted document contains the commands). It is automatically run if you use the EP-Launch program.
EnergyPlus may create several output files. Whether some files are produced depends on the actual simulation (for example, the .rdd file is only produced when you request a Variable Dictionary using the Output:Report object). Similarly, the .dxf file is only produced when a DXF surface report is requested. Common output files are shown in the following table. A complete, up to date list is shown in the “Output Details and Examples Document”.
|Eplusout.audit||Echo of input|
|Eplusout.eso||Standard Output File (contains results from both Output: Variable and Output:Meter objects).|
|Eplusout.eio||One time output file|
|Eplusout.rdd||Output variable Data Dictionary|
|Eplusout.dxf||DXF (from Output:Report,Surfaces,DXF;)|
|Eplusout.mtr||Similar to .eso but only has Meter outputs.|
|Eplusout.mtd||Meter details report - what variables are on what meters and vice versa.|
|Eplusout.end||A one line summary of success or failure (useful for Interface programs)|
|Eplusout.dbg||From Debug Output object - may be useful to support to help track down problems|
||Not directly from EnergyPlus - produced by utility programs that read the .eso file and produce output files for spreadsheet programs|
|Eplusout.sln||Similar to DXF output but less “formatted”. Results of Report Surface, Lines object.|
||Results from the Zone Sizing object with extension noted by the Sizing Style object. This file is “spreadsheet” ready.|
||Results from the System Sizing object with extension noted by the Sizing Style object. This file is " spreadsheet" ready.|
|Eplusout.bnd||This file contains details about the nodes and branches. Useful in determining if all your nodes are connected correctly.|
||Results from various “Report Table” and a few other reporting commands. The extension is from the “style” command and this file is “spreadsheet” ready.|
