TRANSCRIPT
Lecture 3: Output—Reports, Variables, and Meters
Material prepared by GARD Analytics, Inc. and University of Illinoisat Urbana-Champaign under contract to the National Renewable Energy
Laboratory. All material Copyright 2002-2003 U.S.D.O.E. - All rights reserved

Importance of this Lecture to the Simulation of Buildings
Running a simulation program results in the production of output data
Understanding the output data and its format can help avoid mistakes and save time
3
Purpose of this Lecture
Gain an understanding of:
Different output files of EnergyPlus
Which output will be the most useful and how to get it
Define accumulation “meters” to save time in processing and analyzing results
4
Keywords Covered in this Lecture
Report
Report Variable
Report Meter
5
Output Data Format
Same philosophy as for input; somewhat human readable output files
EnergyPlus can perform some output processing to help limit output size
User definable variable level reporting
6
Output Reporting Flexibility
User can select any variables available for output
User can specify output at time step, hourly, daily, monthly, or environment intervals
User can schedule each output variable
User can select various meters by resource and end-use
7
Types of Output
Report Variables
Report Meters
Default Reports
Optional Reports
8
Output Files
Eplusout.<ext> Filename.<ext>
eio Initialization Output – environments, constructions, global settings
eso Standard Output – numeric data

ESO vs. CSV
ESO “Raw” data in comma separated format
“Stream of conscience” report—variables print as they are determined
Less convenient for viewing variables
CSV Organized data in comma separated format
Each row contains data in columns for a particular time step
More convenient for viewing variables
Requires an .rvi file and must run post-processing program
EP-Launch handles this automatically

Meters
Accumulate multiple outputs of same form
Appropriate variables are grouped onto “meters” for reporting purposes
May ease analysis of output
Values are put onto the eplusout.mtr file
Meter component details in eplusout.mtd file
Meter names applicable for the simulation are shown on the Report Data Dictionary file
Meter names are of two forms: <FuelType>:<MeterType>
<EndUseType>:<FuelType>:<MeterType>

Summary
ESO (EnergyPlus Standard Output) file provides user with “raw” output data from EnergyPlus run
CSV file is a version of the ESO file that is in a format more readily usable in a spreadsheet program
Meters and meter output are convenient ways of grouping data for output analysis
