RE: [EnergyPlus_Support] HVAC Descriptions

["Andy Tindale" <andy@xxxxxxxxxxxxxxxxxxx>]

You can serve multiple zones in DesignBuilder with a single unitary system
by selecting an HVAC template using the 'Unitary multizone' compact HVAC
type.  In this case, it is necessary to set one of the zones as being
thermostatic control zone.

I am not sure if there is a way within DesignBuilder to serve multiple zones
on
the same unitary system.

One approach is to delete all of the DesignBuilder HVAC input objects, then
use
COMPACT HVAC:ZONE:UNITARY and COMPACT HVAC:SYSTEM:UNITARY to create a single
HVAC system serving multiple zones, designating one zone to be the control
zone.
