I have 0 unmet hours, but I have 4420 hours unmet according to Simple ASHRAE 55-2004. What can I do to improve this?

edit

My cooling setpoint for summer is 24C. My cooling setpoint for winter is 29.4C. My heating setpoint for summer is 15.6C. My heating setpoint for winter is 21C.

I have some thermal zones that do not have a heating and cooling requirement. Therefore, I have not provided a heating and cooling schedule to those zones. Would this cause the unmet hours according to ASHRAE 55 2004?

So far I have changed the scheduling for equipment, people, lighting, and all everything else I could think of.

The one thing I have not done is modify the humidity and other settings in the thermal tab. The sizing factor for my cooling and heating are 1.25.

I am not sure what else I can do.
