Example Input Files[LINK]
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. ! !

Run Period (Weather File): Winter 1/14, Summer 7/7, CHICAGO_IL_USA TMY2-94846 ! ! Run Control: Zone and System sizing with weather file run control (no design days run) ! ! 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. ! ! Floor Area: 463.6 m2 (5000 ft2) ! Number of Stories: 1 ! ! Zone Description Details: ! !

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 ExcelTM. Like the .rvi, the .mvi file can be used with the .mtr file to create a similar version for “metered” outputs.
