Another method:



Don’t provide any cooling thermostat schedule to the zone  (right click
and select restore default) and set the crankcase heat to 0 kW on unitary
power tab.

Yes, no cooling and it’s HW heating, not furnace.  However it has zone
dampers.

1.	Put the cooling on a separate electric meter so that it does not
report it, or set the cooling thermostat set point to the maximum
allowable value or a combination of these.
2.	VVT is an available system type.. not sure if you were asking
because of the no cooling.
3.	Utility bill matching is very difficult, you will need to know
more specifics about the schedules of operations, equipment efficiencies,
lighting efficiencies... so on.  If it is close +-10% I would not worry
about it, otherwise you will need to massage the model to fit existing
conditions.

Hi all,



I have a VVT type system but with no cooling, heating only.  What kind of
system type I can model that?  When I chose the HW furnace with zone
ventilation, the heating consumption was smaller than the utility bill.
If I chose other type of system (package VVT, MZ, etc.), it’s assuming it
has some kind of cooling.



Thanks in advance for your help.
