Energy+.ini¶
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".
| FileName | Description |
|---|---|
| Eplusout.audit | Echo of input |
| Eplusout.err | Error file |
| 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 |
| Eplusout. \< ext > | 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. |
| Epluszsz. \< ext > | Results from the Zone Sizing object with extension noted by the Sizing Style object. This file is "spreadsheet" ready. |
| Eplusssz. \< ext > | 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. |
| Eplustbl. \< ext > | Results from various "Report Table" and a few other reporting commands. The extension is from the "style" command and this file is "spreadsheet" ready. |
