Issue with internal source construction in OpenStudio

asked 2022-01-11 05:44:42 -0600

updated 2022-01-11 14:38:14 -0600

for the first time I'm trying to set up a model with passive cooling ceiling, using ground heat exchanger. I get some errors, but I see the settings in UI, I'm not sure what is missing. Could somebody help me with this?

A few Site:GroundTemperature variants like KusudaAchenbach are not supported by OpenStudio per se. You would need an EnergyPlus Measure (check out "Advanced Topics") to complete the task.

I don't think I can find an existing measure to do this from the list. And I haven't try to write a measure myself, difficult
