Hello, all,

I am simulating a 3-floor, 78000 ft2 office building with eQUEST for LEED CS. For the ASHRAE basecase (VAV system), there are many zones with the unmet heating setpoint. The unmet hours around 100-180 which are 50 hours more than than the proposed design case (water-loop heat pump system). Is there any method that can reduce the unmet hours in the basecase VAV system? I tried to increase the sizing ratio for heating and etc., but this does not reduce the unmet heated hours.

Any suggestions?

Thanks.

Regards,

David
