For instance, location information (latitude, longitude, time zone, altitude) appears on this file. The EnergyPlus Invariant Output (EIO) is a text file containing output that does not vary with time. Usually postprocessing will be done on this file in order to put it in a format that can be read by a spreadsheet however a quick visual inspection of the file does show whether the expected variables are output at the desired time step. Although the MTR is a text file, it is not easily interpretable by a human. The contents of the file are controlled by Report Meter commands in the IDF file. Values are grouped onto logical meters and can be viewed the same way that the ESO variables are used. Meters are a powerful reporting tool in EnergyPlus. The format of the file is similar to the ESO file. The EnergyPlus Meter Output (MTR) is a text file containing the time varying simulation output. Although the ESO is a text file, it is not easily interpretable by a human.

The contents of the file are controlled by Report Variable commands in the IDF file. The format of the file is discussed in the Guide for Interface Developers and the InputOutputReference. The EnergyPlus Standard Output (ESO) is a text file containing the time varying simulation output. dit can be used when you need to see the context of the error message to fully ascertain the cause. Note that both eplusout.err and dit will show the error messages caused by input syntax errors however only eplusout.err will show errors issued during the actual simulation. This is an text file which echoes the IDD and IDF files, flagging syntax errors in either file. ************* EnergyPlus Terminated-Error(s) Detected. ** Fatal ** Errors occurred on processing IDF file. No action required.Īn example of an error message due to an input syntax error is: ** Severe ** Did not find " DessignDay" in list of Objects Informative, usually a follow-on to one of the others. The following table illustrates the necessary actions.Įrror Message Levels - Required Actions Error Level A fatal error causes the program to terminate immediately. There are three levels of error severity: fatal, severe, and warning as well as simple “message” lines. Error messages are issued by EnergyPlus during its input phase or during the simulation. This is the first output that should be examined after a simulation. eplusout.err Ī text file containing the error messages issued by EnergyPlus. More information (and more up-to-date) about output files is shown in the Output Details and Examples Document. The data format is described in this document in the section: EnergyPlus Weather File (EPW) Data Dictionary. The EnergyPlus weather file is an ascii file containing the hourly or sub-hourly weather data needed by the simulation program. and are used by the EP-Launch program when the Utilities tab is used to execute the Basement and Slab programs, respectively. The “weather” portion of the initialization file is unused for normal EnergyPlus.

This is automatically generated during the install and may be the “shortened form” of these folder names. C:\Program Files\EnergyPlusV2-0-0 or C:\EnergyPlusV2-0-0). Under, dir should indicate the folder where EnergyPlus is installed (e.g. This file, using the actual directories of the install, will be created during the install. It is an optional ascii input file that allows the user to specify the path for the directory containing Energy+.idd.

This is the EnergyPlus initialization file. IMF files are not directly read by EnergyPlus. Output from the EP-Macro program will be the standard in.idf format. The input macro file (IMF) is an ascii file that is formatted for the EP-Macro program. Many example files are installed as part of the EnergyPlus installation. The Guide for Interface Developers shows examples of IDF input. The input data file (IDF) is an ascii file containing the data describing the building and HVAC system to be simulated.

The Guide for Interface Developers contains a full description of the input data dictionary. This file is analogous to the DOE-2 keyword file.

The input data dictionary (IDD) is an ascii (text) file containing a list of all possible EnergyPlus objects and a specification of the data each object requires. The following files are input to the EnergyPlus program.
