I'm building a parametric E+ simulation using jEPlus. I want to include in each idf some weather-related objects (e.g. I want to change the HVAC availability schedule, depending on which weather file is used for that simulation). Any hints for doing that? Better using EPMacro or a python code?
Just in case someone will need it, I solved the problem in this way: I wrote a python script (as suggested by Yi Zhang), included in the parameter tree. The script performs the following simple operations: 1) it opens the in.epw file in the job folder (I thought that was easier than extracting the job name, but that's up to you); 2) it reads the location name in the first line of the epw file; 3) depending on the location name it appends a different group of objects to the in.idf file.
Is it possible to share how you did this in more detail or possibly a script example?

Hmm, it is a tough one! If running each weather file as a separate project is not an option for you, the only workaround I can think of now is using Python script, although it has its own limitations. What does your project do? If it involves a 'small' number of weather and availability schedule combinations, you may create the list manually using the job list file...
Doing it maually is definitely an option (I just have 3-5 different climates, each one having a related group of objects in the idf). I was just looking for a smart way to do it.
For 3-5 climates, you can probably run them as separate projects :-) Does the climate-dependent group of objects themselves contain parameters to be processed by EP-Macro or manipulated by jEPlus? If they are just static text blocks, Python will do. I can expand this to a answer if you want.
As for now they are static group of objects. I was thinking that Python should read the job name and, depending on the number associated with the weather file, add a different text block to the idf. But maybe you had a different idea, so if you could expand it to an answer, it would be highly appreciated :)
:-) that's exactly what I was to suggest!
