at least you are getting heating and the system is operating. To get rid of
your unmet hours, you will have to refine the model. First put the accurate
loads and envelope in (including getting rid of the exterior floor I mentioned
previously) and make sure your schedules (lighting, equipment, occupancy etc.)
are reasonable. Then change some interior walls to air walls as applicable
(interior walls that aren’t actually there, such as corridors that open
into a space without a door) to more evenly distribute loads within each floor.
Finally, add system capacities and zonal air flows. Perimeter baseboard heating
may be needed in the design if the windows and walls are as poor as your
previous attached model suggests. You might also create a custom capacity curve
(HEAT-CAP-FT) for the Mitsubishi heat pump.<o:p></o:p></span></font></p>

 I even used "system per zone" so that each zone is
controlled independently.  Even coming strait out of the wizard,
there are plenty of heating hours not met.  I understand that a
stand air-to-air heat pump will be unable to operate in very cold
weather, but that is where the supplemental heat should take over to
get rid of any unmet hours.  I have attached this model.<o:p></o:p></span></font></p>

Hyper Heating Inverter Y-Series Heat Pump.    This system (in heating
mode) uses electric resistance heat to warm the outdoor air before it reaches
the outdoor coils.  This ensures that heat transfer will occur between the
OA and the outdoor coil, and allows for operation at temperatures as
low as -13*F.  At first I thought that eQuest can
not exactly model a system like this, so maybe eQuest is
not allowing any heat transfer between the cold coil and the cold
air.  But then I tried again using the RESVVT, and it seems to work well,
even in the middle of winter.  My only objection to using the RESVVT is
that I would like to have control over the OA.<o:p></o:p></span></font></p>
