I am working with a large model of a hospital which was created in ee4 for the doe2.1e engine. The model was created when the hospital was designed, and I am trying to modify it to better match the operating conditions of the hospital to identify energy saving opportunities. I want to set the temperature setpoints back to 53F, but when I do this, it causes the systems report to crash, and gives an error for all zones when the diagnostic comes up. If i run the doe file from the command line, it says that it is the systems report which causes the simulation to crash. The loads report generates with no problems. I have no idea how to solve this as Im not very familiar with the DOE engine.
