I was modifying a DOE prototype downloaded from BCL in Openstudio. I came into some errors when I deleted some zones (cause I wanted to reduce the building size and room quantity), I noticed that there are EnergyManagementSystems(EMS) remained in the files(when I checked in text), so I deleted it and the simulation runs. My question is, how comes that I have to editing in text while I was using an Openstudio software? Is there way that I can modify the EMS in Openstudio?
