Re: [EnergyPlus_Support] Simulate a partly underground icehouse on EnergyPlus

["Jean Marais jeannieboef@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

There are no "severe" errors here. You will find plenty of examples and references to ground temperatures in the documentation.

As for the unused xxxx... Think of them as templates that you have defined, but are currently not assigning to anything.

I am new to EnergyPlus and Openstudio. I have a project which is required to simulate the temperature change inside a partly underground ice house. However,i encounter a severe problem during simulation. Here is the error shown below. I have no idea about how to create the ground temperature file and why there is so many unused constructions in input. My model is supposed as no lighting, no people, no activity, no HVAC, no electric,no everything except the building. Hope someone could help me solve it.
