Error : Undefined local variable

I am solving baseline model using measure for multi-storey building. During the execution of measure one error encountered. Could you please look into it & suggest the way of rectify the model.image description

Here I attached my file for the concern.https://drive.google.com/file/d/1518ekXXEeD_AJV4FGq98dfpH8cyHAFNz/view?usp=sharing

Have you tried running your model before applying the baseline measure?

In the model you linked, 500 out of 666 spaces do not have a thermal zone. EnergyPlus is based on thermal zones and will fail if you have spaces in your model without them.

Get your proposed model running first before trying to implement the baseline building measure.

Thank You.

As per your suggestion I changed all the spaces as unconditioned & run the simulation. Baseline for hvac loop is working fine But when I use base line measure for space it was showing the same error as per the attachment. link text

I get many severe errors in the .osm file you linked to above that cause the simulation to fail. There are multiple surfaces with different numbers of vertices than the surfaces they are matched to. To fix this, first greatly reduce the number of spaces in your model. Combine spaces with like internal loads and exterior exposure, and assign like adjacent spaces to the same thermal zone. Then run the surface intersection and matching measure on BCL. Run your model without any measures for 1 week and see if you can get the model to simulate without errors.

Can you please give me a favor through a video tutorial? I couldn't understand how to make number of rooms into a single space where each room having different loads. If I run surface matching through BCl it creates more number of surfaces. I would be more grateful for your tutorial.
