Output File List¶
Following are the native file names that are output from EnergyPlus; native -- directly out of EnergyPlus. Usually you will not see these file names as batch files and interfaces will change them to be \<file name>.\<ext> or in some instances \<file name>\<qualifier>.\<ext>. Usually the extension is the important piece and is described in the following table.
| Output File Name | Description | EP-Launch File Name |
|---|---|---|
| eplusout.audit | Echo of input, includes both IDD echo and IDF echo -- may have errors shown in context with IDD or IDF statements | \< filename > .audit (without echoing IDD unless errors in IDD). |
| eplusout.bnd | This file contains details about the nodes and branches. Useful in determining if all your nodes are connected correctly. May be used to diagram the network/ nodes of the HVAC system. | \< filename > .bnd |
| eplusout.dbg | From Debug Output object -- may be useful to support to help track down problems | \< filename > .dbg |
| eplusout.dxf | DXF (from Output:Surfaces:Drawing,DXF;) | \< filename > .dxf |
| eplusout.edd | Descriptive output from the EMS portion | \< filename > .edd |
| eplusout.eio | Contains several standard and optional "report" elements. CSV format -- may be read directly into spreadsheet program for better formatting. | \< filename > .eio |
| eplusout.end | A one line summary of success or failure (useful for Interface programs) | Not saved in the standard EPL-Run script file. |
| eplusout.epmidf | Output from EPMacro program -- contains the idf created from the input imf file | \< filename > .epmidf |
| eplusout.epmdet | Output from EPMacro program -- the audit/details of the EPMacro processing | \< filename > .epmdet |
| eplusout.err | Error file -- contains very important information from running the program. | \< filename > .err |
| eplusout.eso | Standard Output File (contains results from both Output:Variable and Output:Meter objects). | \< filename > .eso |
| eplusout.log | Log of items that appear in the command file output from the run. | \< filename > .log |
| eplusout.mdd | Meter names that are applicable for reporting in the current simulation. | \< filename > .mdd |
| eplusout.mtd | Meter details report -- what variables are on what meters and vice versa. This shows the meters on which the Zone: Lights Electric Energy appear as well as the contents of the Electricity:Facility meter. | \< filename > .mtd |
| eplusout.mtr | Similar to .eso but only has Output:Meter outputs. | \< filename > .mtr |
| eplusout.rdd | Variable names that are applicable for reporting in the current simulation. | \< filename > .rdd |
| eplusout.shd | Surface shadowing combinations report | \< filename > .shd |
| eplusout.sln | Similar to DXF output but less structured. Results of Output:Reports,Surface, Lines object. | \< filename > .sln |
| eplusout.sql | Mirrors the data in the .eso and .mtr files but is in SQLite format (for viewing with SQLite tools). | \< filename > .sql |
| eplusssz. \< ext > | Results from the Sizing:System object. This file is "spreadsheet" ready. Different extensions (csv, tab, and txt) denote different "separators" in the file. | \< filename > Ssz. \< ext > |
| epluszsz. \< ext > | Results from the Sizing:Zone object. This file is "spreadsheet" ready. Different extensions (csv, tab, and txt) denote different "separators" in the file. | \< filename > Zsz. \< ext > |
| eplusmap. \< ext > | Daylighting intensity "map" output. Different extensions (csv, tab, and txt) denote different "separators" in the file. | \< filename > Map. \< ext > |
| eplusout.dfs | This file contains the hourly pre-calculated daylight factors for exterior windows of a daylight zone. | \< filename > DFS.csv |
| eplusscreen.csv | Window screen transmittance (direct and reflected) "map" output. | \< filename > Screen.csv |
| eplustbl. \< ext > | Results of tabular and economics requests. Different extensions (csv, tab, and txt) denote different "separators" in the file. | \< filename > Table. \< ext > |
| eplusout.svg | Results from the HVAC-Diagram application. SVG is a Scalable Vector Graphics file for which several viewers can be found. | \< filename > .svg |
| eplusout.sci | File of cost information | \< filename > .sci |
| eplusout.delightin | File produced during DElight simulations -- descriptive of EnergyPlus inputs into DElight inputs. | \< filename > delight.in |
| eplusout.delightout | File produced during DElight simulations -- basic results from DElight simulation. | \< filename > delight.out |
| eplusout.wrl | VRML output from (Output:Reports, Surfaces, VRML) | \< filename > .wrl |
Table: EnergyPlus Basic Output Files
In addition to the basic output files from EnergyPlus there are three standard "hybrid" output files. These are called "hybrid" because they are a result of post-processing after EnergyPlus has completed. Note that if there is an error during processing, these will not normally be "complete".
| Output File Name | Description | EP-Launch File Name |
|---|---|---|
| eplusout. \< ext > | "spreadsheet" ready file that contains either all the report variables requested (default: up to limit of 255) from the input file or specific ones specified by the user. Different extensions (csv, tab, and txt denote different "separators" in the file. | \< filename > .csv or \< filename > .tab or \< filename > .txt |
| eplusmtr. \< ext > | "spreadsheet" ready file that contains either all the report meter requests (default: up to 255) from the input file or specific ones specified by the user. Different extensions (csv, tab, and txt denote different "separators" in the file. | \< filename > Meter.csv or \< filename > Meter.tab or \< filename > Meter.txt |
| readvars.rvaudit | Results of any "ReadVarsESO" execution in the current batch run. | \< filename > .rvaudit |
