Same question here as in this link: https://unmethours.com/question/3450/modeling-run-around-loop-heat-recovery-in-energyplus/?answer=3454#post-id-3454

But I am unfamiliar with working directly in Energyplus. I am instead working in Openstudio. Any additional responses to the above link from an OS perspective?

For example I am unfamiliar with how to write an EMS loop script to track the district loop set point to the outside air temperature. Is this as complicated as it sounds?
