In the case that outdoor air is considered, Ideal Loads handles the treatment (pre-heating or pre-cooling) of this outdoor air (in my case, necessary to oblige to minimum ventilation rates) separately from the conditioning of the indoor zone air. So, Supply Air will have bigger annual sums than Zone Total for heating (because pre-heating for ventilation is included in Supply Air), and smaller for cooling because the outdoor air provides some (free) cooling, i.e.: when the outdoor air is colder than indoor exhaust air, the outdoor air in the mix results in less energy required (to be taken) to cool the mix to supply conditions than it does without the outdoor air included (Zone Total).

Thus, Supply Air is the closest output to the real thermal energy the HVAC system uses.

In the case that outdoor air is considered, Ideal Loads handles the treatment (pre-heating or pre-cooling) of this outdoor air (in my case, necessary to oblige to minimum ventilation rates) separately from the conditioning of the indoor zone Zone air. So, Supply Air will have bigger annual sums than Zone for heating (because pre-heating for ventilation is included in Supply Air), and smaller for cooling because the outdoor air provides some (free) cooling, i.e.: when the outdoor air is cooler than indoor air, the outdoor air in the mix results in less energy required (to be taken) to cool the mix to supply conditions than it does without the outdoor air included (Zone).
