The zone sensible loads are shown in the "HVAC Sizing Summary" table output, "Zone Sensible Cooling" and "... Heating" subtables. The sensible loads are used to calculate the zone supply air flow rates using the supply temperatures specified in Sizing:Zone. Any sizing factors in Sizing:Parameters or Sizing:Zone are already applied in the "User" values in this table. Note that the zone "Minimum Outdoor Air Flow Rate" is listed in this subtable, but it is not included yet in the load, these get used later.
The "System Design Air Flow Rates" subtable shows the system air flow rates (which may be coincident or non-coincident depending on the Sizing:System inputs) that are used to size the central system coils.
The "Coil Sizing Summary" subtable shows the entering and leaving conditions used to design the coil. Entering conditions are based on the zone conditions at the time of the system peak mixed with outdoor air. Leaving conditions are from the Sizing:System inputs. The coil sizing also adds in supply fan heat. For cooling coils, the total capacity includes the latent load.
If you want to see the various load components impacting the coil, run a Sizing Period (design day) simulation and use output variables to report the zone sensible load, the zone latent loads, the zone mechanical ventilation loads, and the fan heat.
