Hello, as for the â??Zone Sensible Heatingâ?? for the highlighted zone the â??Calculated Design Load [W]â?? is equal to 0 although the â??Thermostat Setpoint Temperature at Peak Loadâ?? (24°C) is not met (I have attached an image where you can see part of the html report). The zone is served by a VAV system that supplies many zones. There is a local reheat coil, whose power is autosized equal to 0 and therefore the zone setpoint temperature is not met.
What I consider really strange is that other zones are served by the same VAV system and have the same parameters for Sizing:zone but their â??Calculated Design Load [W]â?? is greater than 0 (e.g. 00:SPOGLIATOIOFEMMINILE).
