Baseline has space heat, but proposed has zero space heat

Dear All,

I have a model located in Mexico. The baseline is equipped with PSZ+Heat
pump and proposed is equipped with VFD + Heat pump. For some reasons, the
baseline has a normal space heat, but the proposed shows 0 space heat. The
envelop, schedule, setpoints, outside air flow rates are all the same.
1. What could be the possible reason for something like this?
2. Does anyone know how eQuest calculate the heating/cooling capacity at
the system and zone level? For example, I set up the cooling and heating
capacity for the system and set up setpoints for each zone. So in the SV-A,
it only shows the heating/cooling capacity of the system, and for each zone
will be zero heating and cooling capacity?
3. What is the extraction rate (KBTU/HR) and addition rate(KBTU/HR) in
SV-A? Where are they from?
