Auxiliary Programs
Introduction[LINK]
This document will describe several of the “auxiliary
programs” of the EnergyPlus system in more detail. Some of
these programs are only available or only distributed for
certain platforms. Typically, the programs are available on
the Windows platform. Within the descriptions, other platforms
will be noted as applicable. These programs include:
Weather Converter Program (aka
“Weather”)
Ground Heat Transfer in EnergyPlus -
Procedure for Ground Temperature creation
View Factor Calculation Program -
Auxiliary program used to calculate View Factors which can be
used with EnergyPlus
Using Older Version
Input Files - Transition - to convert input files
from one version to another upon release of a new version
EPDraw - Create DXF files from your input
files
Input Macros - Use a macro language to
increase efficiency in creating EnergyPlus input files.
Unfortunately, IDF files containing macros cannot be read in
the IDF Editor.
HVAC Diagram - Use a post processing
program to diagram your HVAC inputs.
CoeffConv/CoeffCheck - Convert DOE-2
temperature dependent curves (Fahrenheit) to EnergyPlus
temperature curves (Centigrade/Celsius)
ExpandObjects - Some technical details of
the Expand Objects program which preprocessed HVACTemplate:*
and GroundHeatTransfer:* objects for use inside
EnergyPlus.
CSVproc - Get simple statistics from CSV
output files.
convertESOMTR - convert your outputs to
Inch-Pound (default) or other custom unit conversions.
CalcSoilSurfTemp Program - calculate soil
surface parameters used in the Earth Tube simulation
HVAC Performance Curve Fit Tool- generates
HVAC performance curves in EnergyPlus IDF format
Parametric Spreadsheets - Parametric
spreadsheets are available to help illustrate or calculate
some parameters/coefficients.
ParametricPreprocessor -
Special objects can be inserted in IDF files and generate a
series of IDF files from a single source IDF file that
contains parametric objects and expressions. Unlike using the
macro language, these input files are capable of being read in
the IDF Editor.
AppGPostProcess - Appendix G PostProcessing
program - The ASHRAE 90.1 Appendix G postprocessing
program takes simulation outputs and processes them to help
meet Appendix G requirements..
BLASTTranslator - The BLAST translator can
take BLAST (Building Loads Analysis and System Thermodynamics)
input files and make them ready for running in EnergyPlus.
DOE2Translator - The DOE-2 translator can
take DOE-2 program input files and make them ready for running
in EnergyPlus.
Running Console Applications - this
section describes how to run console applications that are
part of EnergyPlus and how you might modify these to your
specific needs. Instructions for running individual programs
are included in their descriptions.
Technical Details of Running EnergyPlus -
this section gives full instructions on both EP-Launch and the
IDF-Editor as well as some more details on running EnergyPlus
manually.
EP-Compare - A utility to graphically
compare tabular results from multiple simulation files.
