The EnergyPlus install includes a sample of example input files. For the most part, the developers create these files to illustrate and test a specific feature in EnergyPlus. Then, we pass them along to you for illustrative purposes. The install contains two spreadsheet files related to the example files:
ExampleFiles.xls - lists all the files available – whether through the install or through an external site.
ExampleFiles-ObjectLink.xls - illustrates the first 3 occurances in the example files of an object.
Following convention, each example file should have at the top a set of comments that tell what the purpose of the file is and the key features.
For example, the file titled “5ZoneAirCooled.idf” has:
! 5ZoneAirCooled.idf
! Basic file description: 1 story building divided into 4 exterior and one interior conditioned zones and return plenum.
!
! Highlights: Electric chiller with air cooled condenser; autosized preheating and precooling water coils in the
! outside air stream controlled to preheat and precool setpoints.
!

! Building: Single floor rectangular building 100 ft x 50 ft. 5 zones - 4 exterior, 1 interior, zone height 8 feet.
! Exterior zone depth is 12 feet. There is a 2 foot high return plenum: the overall building height is
! 10 feet. There are windows on all 4 facades; the south and north facades have glass doors.
! The south facing glass is shaded by overhangs. The walls are woodshingle over plywood, R11 insulation,
! and gypboard. The roof is a gravel built up roof with R-3 mineral board insulation and plywood sheathing.
! The windows are of various single and double pane construction with 3mm and 6mm glass and either 6mm or
! 13mm argon or air gap. The window to wall ratio is approxomately 0.29.
! The south wall and door have overhangs.
!
! The building is oriented 30 degrees east of north.

In addition to the idf files, usually an .rvi and perhaps a .mvi of the same file set is included. As discussed previously, the .rvi is used with the ReadVarsESO post-processing program and the .eso file to create a .csv file which can be read easily into Excel™. Like the .rvi, the .mvi file can be used with the .mtr file to create a similar version for “metered” outputs.
