How does energyplus read idf-files?

Hi

How does energyplus read idf-files? Does the order of e.g. materials, constructions, building information ect. matter in terms of energyplus (EP-launch) understanding the idf-file?

Thanks in advance!

The order of how objects appear in the IDF file _should_ not make a difference in the calculations in EnergyPlus. It will make a difference in the ordering of output related to the input objects.

Nope, the IDF editor doesn't care about the order.

Contrary to eQuest for example, every objects are linked by references (one way or another), so the position of the objects within the file doesn't matter.

In fact, in the IDF editor you have the option to choose how to save your file: "Sorted', "Original with New at Top", "Original with New at Bottom".
