Any EnergyPlus object may be 28 Start EP launch viewed and edited using a spreadsheet-like grid. For inputs with several 29 Select the IDF file options, a list is provided. When a numeric input has a range of valid values, 30 During Simulation Run those values are displayed. It also automatically provides a list of object 31 Run Status 32 Click DXF names when an object needs to be linked to another. By displaying all 33 Drawing in VoloView objects of the same kind next to each other in a grid, it is easy to see how 34 Click Orbit button inputs are different across the building. The IDF Editor outputs an EnergyPlus 35 3D view of the Drawing 36 Output data in Excel input file with proper syntax and comments to help the user understand the input values. In addition, the IDF Editor converts standard inch-pound units into SI units compatible with EnergyPlus. The IDF Editor does not check inputs for validity, although some numeric fields are highlighted if out of range. Some info on IDF editor.
