How do I connect the preprocessor schedules imported from an EnergyPlus to objects in OpenStudio?

Hi Everyone,

I recently imported an .idf file into OpenStudio. The .idf file included the basement pre-processor schedules . Once in OS, I defined the boundary conditions for each of the basement walls and floor as "Other Side Coefficient" just I had done previously in EnergyPlus under the "Facilities" tab. The problem, however, occurs when I attempt to define the Outside Boundary Condition Object by dragging the pre-processor schedules over. For some unknown reason, OS is not allowing me to define the Object using the EnergyPlus schedule that has been imported over.

Any suggestions on how to fix this?

OpenStudio has not yet wrapped the SurfaceProperty:OtherSideCoefficients or SurfaceProperty:OtherSideConditionsModel in the OpenStudio model object hierarchy so it is currently not possible to specify those boundary conditions for an OpenStudio model. I can understand that there may be confusion here because the OS:Surface object does accept 'OtherSideCoefficients' and 'OtherSideConditionsModel' for its 'Outside Boundary Condition' property. The best current workflow would be to write an EnergyPlus measure (that runs after the OSM is converted back to EnergyPlus IDF) which creates SurfaceProperty:OtherSideCoefficients objects, connects those to your schedules, and then loops through surfaces to connect them to the SurfaceProperty:OtherSideCoefficients objects.
