idf network connections

retag add tags

The named connections between objects in the EnergyPlus idf can help to understand the structure of the simulation file. For airflow networks and HVAC systems, these connections are important to understand, but difficult to grasp. - Other than explicit reference by name, how could the idf be queried to find connections to other objects ?
- What types' of connections would be useful to filter by ? i.e 'HVAC', 'geometry', 'AFN'

@Maddog007. Is this a question or a poll of potential users?

@Maddog007 consider adding the 'idf' tag to this question.

This question isn't crystal clear. I see you used the tag "eppy" but didn't mention it in the question. Are you looking for a specific eppy solution? Can you add more information please? thanks!

I am not sure I understand what you looking to do, but the IDD has some markup in it that may be useful. The so-called slash codes may help you find which IDF input fields have connections to others. You might want to study how "/reference" and "/object-list" are used in the input scheme. There is also "/type node" for input fields that are system nodes.

Also note that there are input field naming practices that might be of use to establish connections. When input objects reference another object, there is supposed to be a pair of input fields, one where the title of the input field ends in "Object Type" and its companion ends in "Object Name." When a input field is supposed to contain the name of a system node, the name should end in "Node Name."
