I have tried running your IDF, but do not know what you are trying to do.
GJ is GigaJoules.
I do not know why you have so many designDay objects. Only two are needed for sizing. Four, if you are trying the four season solar beam study, and/or the transistion operation of the HVAC system..
Where do you intend to insert the storage tank? The pipe object itself is not in the correct order postion of the IDF, therefore the branch was not recognized and flagged as a severe error.
If you want to discharge the tank load in a zone, then it should be declared as a zone equipment, or a tank placed in a zone.
I do not know how you can charge an ICE STORAGE TANK. Is it a new object available in EPlus? This is the first time I come across the ThermalStorage:Ice:Detailed. I shall try to look it up in the ref. manuals.
You should use a refrigerated room and control its temperature for the experiment. The PCM may be installed as the walls of the centrol zone with the four other peripheral zones as in the 5-zone building as controlled zones.
Without the ice strage branch, the IDF run was sucessfull.

Subject: [EnergyPlus_Support] Detailed ICE storage - for PCMs? Nodes & curves question
I am attempting to experiment with the detailed Ice storage object, as I noticed it has "freezing temperature of storage medium" rather than assuming freezing temp for water of 0C/32F. I added the objects from the example file to to a model I have been working on and attempted to connect the nodes, but when trying to run E+ crashes. Also I was thinking to use data from DSC tests of PCM for the charge and discharge curves, but am not sure how to approach it. (I am guessing 1=solid and 0= melt, but am unsure), also I wanted to use the thickness of PCM for the volume of the storage tank, but am unsure about the GJ, what unit would this be? Any advise would be great, and thanks in advance-
