Trying to create an EPC/SBEM certificate however an error pops up saying "At least 1 Zone needed." Version v10.15.1.23
For the Part L calc, there are 3 zones which I've used and for each one a different HVAC system. I've created inputs for each one and when I've tried to run the EPC/results/compliance it comes up with the error message attached.
Throughout all this I have not encountered any error messages in notifications.
I've recreated the model in the same workplace however in a separate workset and the same error message displays.
Not sure what I've done wrong. How can I resolve this?
