Hello,

I am regarding the rationale of diferent zone sizing results when simulating same building and spaces with different ZoneHVAC equipments (LowTemperatureRadiant:Electric, UnitarySistem, IdealLoads...).

I am with "Do Zone Sizing Calculation" and following Bigladder definition it follow some ideal system:

Input is Yes or No. The default is No. Zone Sizing (see Sizing:Zone object) performs a special calculation, using a theoretical ideal zonal system, and determines the zone design heating and cooling flow rates and loads, saving the results in the zone sizing arrays.

Looking at this defition I understand results must be same but there are differences. I don't know if this happens because it takes somehow into account the system modelled.

Thanks in advance
