Hi everyone! Im using OS for my thesis and need to use the operative temperature (OT) instead of air temperature for the thermostat setpoints.

I found this old thread (Link) which had the same question but no sufficient answer other then a depricatet EMS, which i dont think i can adapt to the current OS version. (limited time and programming knowledge) I already tried to edit the code of the old measure, which i got from NREL from an old database, into a current measure without any success (Failed to compute arguments for measure: failed to infer measure name from C:/users...)

It is possible to use Thermostat:OperativeTemperature in EnergyPlus for thermostat setpoints. I was thinking of exporting my OS model to idf and then change the setpoints in EnergyPlus somehow and run the simulation in E+. Would that work or is too much information lost when exporting to idf? I have very limited experience using E+ on its own.

System: Water based heating system, HPWH Tank as Heater with baseboard heating and outdoor air setpoint manager. Software: OpenStudio

Thank you so much for any input! Alex

FWIW I am using OT in this tiny (and flawed!) model, but maybe it is helpful for you?

On the BCL was available an EnergyPlus measure to change set points from air temperature to operative temperature Actually, I can not find anymore on BCL I’ve a copy (translated to Spanish) of it and works fine (I can deliver to you if you send to me an email josepsolebonet@gmail.com).
