Check if you have any spaces in your model that are not assigned to a thermal zone. That should issue a warning in the reporting measure (logged in out.osw file) for a check of EnergyPlus vs. OpenStudio floor area, and would also cause this section of the report to fail.

Yeah I have two unconditioned spaces

@TheEnergyTutor, unconditioned is fine, but if you have spaces in the model that are not assigned to a zone, it can be problematic. Can you confirm if there are any spaces that are not assigned to a thermal zone.

Yeah I never assigned them a thermal zone because they have no heat. I can add it to a new zone.

Yes, it doesn't exist in EnergyPlus if it isn't part of a thermal zone, and that is why the error is coming up because it can't find SQL data for the lights from the space. An unconditioned space is still part of a thermal zone but just doesn't have equipment serving it and generally doesn't have a thermostat. It is important to model it as a zone so you can see what temperatures to expect in the unconditioned space, and because of the impact on adjacent spaces.

Yes adding a thermal zone to my unconditioned spaces resolved this issue. Thanks.
