Hey all,

Still trying to work through the errors of my model. Now I am getting warning errors that can be seen below.

* Warning * Calculated design heating load for zone=1E is zero. * ~~~ * Check Sizing:Zone and ZoneControl:Thermostat inputs.

Happens for all zones.

This is probably a simple fix but it is worrying for when I actually get the simulation working. I have all the autosize options on and have loads in the zones. Don't understand what the cause of this error is.

Thanks again anyone for the help. This community has been great and is helping me become much more familiar with OpenStudio.

Edit: So this might help someone trying to determine the problem. The 2 zones that don't have thermostats don't have that warning. But all the other zones that have thermostats associated with them have the warning.
