Used DesignBuilder...
I am trying to run a full year simulation with all of the HVAC equipment turned off in order to make sure the building is responding to outdoor air temperature fluctuations properly. Around June 11, I start getting a fatal error, "Plant temperatures are getting far too hot, check controls and relative loads and capacities", and the simulation stops. In addition, when I plot the zone temperatures up until the point where the simulation stopped, they are getting to be up to 40 degC, which is much hotter than the outdoor temperature. I do not know how the zone temperatures are getting this high without any of the heating and cooling systems on. I also do not know how to resolve the Plant Temperature error I am getting.
Suggestions?
